	== Function ==		== Function ==
-	[[https://www.uniprot.org/uniprot/ABL1_HUMAN ABL1_HUMAN]] Non-receptor tyrosine-protein kinase that plays a role in many key processes linked to cell growth and survival such as cytoskeleton remodeling in response to extracellular stimuli, cell motility and adhesion, receptor endocytosis, autophagy, DNA damage response and apoptosis. Coordinates actin remodeling through tyrosine phosphorylation of proteins controlling cytoskeleton dynamics like WASF3 (involved in branch formation); ANXA1 (involved in membrane anchoring); DBN1, DBNL, CTTN, RAPH1 and ENAH (involved in signaling); or MAPT and PXN (microtubule-binding proteins). Phosphorylation of WASF3 is critical for the stimulation of lamellipodia formation and cell migration. Involved in the regulation of cell adhesion and motility through phosphorylation of key regulators of these processes such as BCAR1, CRK, CRKL, DOK1, EFS or NEDD9. Phosphorylates multiple receptor tyrosine kinases and more particularly promotes endocytosis of EGFR, facilitates the formation of neuromuscular synapses through MUSK, inhibits PDGFRB-mediated chemotaxis and modulates the endocytosis of activated B-cell receptor complexes. Other substrates which are involved in endocytosis regulation are the caveolin (CAV1) and RIN1. Moreover, ABL1 regulates the CBL family of ubiquitin ligases that drive receptor down-regulation and actin remodeling. Phosphorylation of CBL leads to increased EGFR stability. Involved in late-stage autophagy by regulating positively the trafficking and function of lysosomal components. ABL1 targets to mitochondria in response to oxidative stress and thereby mediates mitochondrial dysfunction and cell death. ABL1 is also translocated in the nucleus where it has DNA-binding activity and is involved in DNA-damage response and apoptosis. Many substrates are known mediators of DNA repair: DDB1, DDB2, ERCC3, ERCC6, RAD9A, RAD51, RAD52 or WRN. Activates the proapoptotic pathway when the DNA damage is too severe to be repaired. Phosphorylates TP73, a primary regulator for this type of damage-induced apoptosis. Phosphorylates the caspase CASP9 on 'Tyr-153' and regulates its processing in the apoptotic response to DNA damage. Phosphorylates PSMA7 that leads to an inhibition of proteasomal activity and cell cycle transition blocks. ABL1 acts also as a regulator of multiple pathological signaling cascades during infection. Several known tyrosine-phosphorylated microbial proteins have been identified as ABL1 substrates. This is the case of A36R of Vaccinia virus, Tir (translocated intimin receptor) of pathogenic E.coli and possibly Citrobacter, CagA (cytotoxin-associated gene A) of H.pylori, or AnkA (ankyrin repeat-containing protein A) of A.phagocytophilum. Pathogens can highjack ABL1 kinase signaling to reorganize the host actin cytoskeleton for multiple purposes, like facilitating intracellular movement and host cell exit. Finally, functions as its own regulator through autocatalytic activity as well as through phosphorylation of its inhibitor, ABI1.<ref>PMID:9037071</ref> <ref>PMID:9144171</ref> <ref>PMID:9461559</ref> <ref>PMID:10391250</ref> <ref>PMID:12379650</ref> <ref>PMID:11971963</ref> <ref>PMID:12531427</ref> <ref>PMID:12672821</ref> <ref>PMID:15556646</ref> <ref>PMID:15031292</ref> <ref>PMID:15886098</ref> <ref>PMID:15657060</ref> <ref>PMID:16943190</ref> <ref>PMID:16678104</ref> <ref>PMID:17306540</ref> <ref>PMID:17623672</ref> <ref>PMID:18328268</ref> <ref>PMID:18945674</ref> <ref>PMID:19891780</ref> <ref>PMID:20417104</ref> <ref>PMID:16424036</ref> <ref>PMID:20357770</ref>	+	[https://www.uniprot.org/uniprot/ABL1_HUMAN ABL1_HUMAN] Non-receptor tyrosine-protein kinase that plays a role in many key processes linked to cell growth and survival such as cytoskeleton remodeling in response to extracellular stimuli, cell motility and adhesion, receptor endocytosis, autophagy, DNA damage response and apoptosis.

Coordinates actin remodeling through tyrosine phosphorylation of proteins controlling cytoskeleton dynamics like WASF3 (involved in branch formation); ANXA1 (involved in membrane anchoring); DBN1, DBNL, CTTN, RAPH1 and ENAH (involved in signaling); or MAPT and PXN (microtubule-binding proteins). Phosphorylation of WASF3 is critical for the stimulation of lamellipodia formation and cell migration. Involved in the regulation of cell adhesion and motility through phosphorylation of key regulators of these processes such as BCAR1, CRK, CRKL, DOK1, EFS or NEDD9. Phosphorylates multiple receptor tyrosine kinases and more particularly promotes endocytosis of EGFR, facilitates the formation of neuromuscular synapses through MUSK, inhibits PDGFRB-mediated chemotaxis and modulates the endocytosis of activated B-cell receptor complexes. Other substrates which are involved in endocytosis regulation are the caveolin (CAV1) and RIN1. Moreover, ABL1 regulates the CBL family of ubiquitin ligases that drive receptor down-regulation and actin remodeling. Phosphorylation of CBL leads to increased EGFR stability. Involved in late-stage autophagy by regulating positively the trafficking and function of lysosomal components. ABL1 targets to mitochondria in response to oxidative stress and thereby mediates mitochondrial dysfunction and cell death. ABL1 is also translocated in the nucleus where it has DNA-binding activity and is involved in DNA-damage response and apoptosis.

		+	== Publication Abstract from PubMed ==
		+	The Abl-SH3 domain is implicated in negative regulation of the Abl kinase by mediating protein-protein interactions. High-affinity SH3 ligands could compete for these interactions and specifically activate the Abl kinase, providing control and a better understanding of the molecular interactions that underlie diseases where SH3 domains are involved. The p41 peptide (APSYSPPPPP) is a member of a group of peptide ligands designed to bind specifically the Abl-SH3 domain. It binds to Abl-SH3 with a Kd of 1.5 microM, whereas its affinity for the Fyn-SH3 domain is 273 microM. We have determined the crystal structure of the Abl-SH3 domain in complex with the high-affinity peptide ligand p41 at 1.6 A resolution. In the crystal structure, this peptide adopts a polyproline type II helix conformation through residue 5 to 10, and it binds in type I orientation to the Abl-SH3 domain. The tyrosine side-chain in position 4 of the peptide is hydrogen bonded to two residues in the RT-loop of the Abl-SH3 domain. The tight fit of this side-chain into the RT-loop pocket is enhanced by conformational adjustment of the main chain at position 5. The SH3 ligand peptides can be divided into two distinct parts. The N-terminal part binds to the SH3 domain in the region formed by the valley between the nSrc and RT-loops. It determines the specificity for different SH3 domains. The C-terminal part adopts a polyproline type II helix conformation. This binds to a well-conserved hydrophobic surface of the SH3 domain. Analysis of two "half"-peptides, corresponding to these ligand parts, shows that both are essential components for strong binding to the SH3 domains. The crystal structure of the Abl-SH3:p41 complex explains the high affinity and specificity of the p41 peptide towards the Abl-SH3 domain, and reveals principles that will be exploited for future design of small, high-affinity ligands to interfere efficiently with the in vivo regulation of Abl kinase activity.

		+	==Function==
		+	[[http://www.uniprot.org/uniprot/ABL1_HUMAN ABL1_HUMAN]] Non-receptor tyrosine-protein kinase that plays a role in many key processes linked to cell growth and survival such as cytoskeleton remodeling in response to extracellular stimuli, cell motility and adhesion, receptor endocytosis, autophagy, DNA damage response and apoptosis. Coordinates actin remodeling through tyrosine phosphorylation of proteins controlling cytoskeleton dynamics like WASF3 (involved in branch formation); ANXA1 (involved in membrane anchoring); DBN1, DBNL, CTTN, RAPH1 and ENAH (involved in signaling); or MAPT and PXN (microtubule-binding proteins). Phosphorylation of WASF3 is critical for the stimulation of lamellipodia formation and cell migration. Involved in the regulation of cell adhesion and motility through phosphorylation of key regulators of these processes such as BCAR1, CRK, CRKL, DOK1, EFS or NEDD9. Phosphorylates multiple receptor tyrosine kinases and more particularly promotes endocytosis of EGFR, facilitates the formation of neuromuscular synapses through MUSK, inhibits PDGFRB-mediated chemotaxis and modulates the endocytosis of activated B-cell receptor complexes. Other substrates which are involved in endocytosis regulation are the caveolin (CAV1) and RIN1. Moreover, ABL1 regulates the CBL family of ubiquitin ligases that drive receptor down-regulation and actin remodeling. Phosphorylation of CBL leads to increased EGFR stability. Involved in late-stage autophagy by regulating positively the trafficking and function of lysosomal components. ABL1 targets to mitochondria in response to oxidative stress and thereby mediates mitochondrial dysfunction and cell death. ABL1 is also translocated in the nucleus where it has DNA-binding activity and is involved in DNA-damage response and apoptosis. Many substrates are known mediators of DNA repair: DDB1, DDB2, ERCC3, ERCC6, RAD9A, RAD51, RAD52 or WRN. Activates the proapoptotic pathway when the DNA damage is too severe to be repaired. Phosphorylates TP73, a primary regulator for this type of damage-induced apoptosis. Phosphorylates the caspase CASP9 on 'Tyr-153' and regulates its processing in the apoptotic response to DNA damage. Phosphorylates PSMA7 that leads to an inhibition of proteasomal activity and cell cycle transition blocks. ABL1 acts also as a regulator of multiple pathological signaling cascades during infection. Several known tyrosine-phosphorylated microbial proteins have been identified as ABL1 substrates. This is the case of A36R of Vaccinia virus, Tir (translocated intimin receptor) of pathogenic E.coli and possibly Citrobacter, CagA (cytotoxin-associated gene A) of H.pylori, or AnkA (ankyrin repeat-containing protein A) of A.phagocytophilum. Pathogens can highjack ABL1 kinase signaling to reorganize the host actin cytoskeleton for multiple purposes, like facilitating intracellular movement and host cell exit. Finally, functions as its own regulator through autocatalytic activity as well as through phosphorylation of its inhibitor, ABI1.<ref>PMID:9037071</ref><ref>PMID:9144171</ref><ref>PMID:9461559</ref><ref>PMID:10391250</ref><ref>PMID:12379650</ref><ref>PMID:11971963</ref><ref>PMID:12531427</ref><ref>PMID:12672821</ref><ref>PMID:15556646</ref><ref>PMID:15031292</ref><ref>PMID:15886098</ref><ref>PMID:15657060</ref><ref>PMID:16943190</ref><ref>PMID:16678104</ref><ref>PMID:17306540</ref><ref>PMID:17623672</ref><ref>PMID:18328268</ref><ref>PMID:18945674</ref><ref>PMID:19891780</ref><ref>PMID:20417104</ref><ref>PMID:16424036</ref><ref>PMID:20357770</ref>
