	[https://www.uniprot.org/uniprot/PIM1_HUMAN PIM1_HUMAN] Proto-oncogene with serine/threonine kinase activity involved in cell survival and cell proliferation and thus providing a selective advantage in tumorigenesis. Exerts its oncogenic activity through: the regulation of MYC transcriptional activity, the regulation of cell cycle progression and by phosphorylation and inhibition of proapoptotic proteins (BAD, MAP3K5, FOXO3). Phosphorylation of MYC leads to an increase of MYC protein stability and thereby an increase of transcriptional activity. The stabilization of MYC exerted by PIM1 might explain partly the strong synergism between these two oncogenes in tumorigenesis. Mediates survival signaling through phosphorylation of BAD, which induces release of the anti-apoptotic protein Bcl-X(L)/BCL2L1. Phosphorylation of MAP3K5, an other proapoptotic protein, by PIM1, significantly decreases MAP3K5 kinase activity and inhibits MAP3K5-mediated phosphorylation of JNK and JNK/p38MAPK subsequently reducing caspase-3 activation and cell apoptosis. Stimulates cell cycle progression at the G1-S and G2-M transitions by phosphorylation of CDC25A and CDC25C. Phosphorylation of CDKN1A, a regulator of cell cycle progression at G1, results in the relocation of CDKN1A to the cytoplasm and enhanced CDKN1A protein stability. Promote cell cycle progression and tumorigenesis by down-regulating expression of a regulator of cell cycle progression, CDKN1B, at both transcriptional and post-translational levels. Phosphorylation of CDKN1B,induces 14-3-3-proteins binding, nuclear export and proteasome-dependent degradation. May affect the structure or silencing of chromatin by phosphorylating HP1 gamma/CBX3.

-	== Publication Abstract from PubMed ==
-	A crystallographic fragment screen was carried out to identify starting points for the development of inhibitors of protein kinase Pim-1, a potential target for tumour therapy. All fragment hits identified via soaking in this study turned out to bind to the unusually hydrophobic pocket at the hinge region. The most potent fragments, two cinnamic acid derivatives (with a best IC(50) of 130 microM), additionally form a well defined hydrogen bond. The balance between hydrophobic and polar interactions makes these molecules good starting points for further optimization. Pim-2 inhibitors from a recently reported high-throughput screening campaign also feature a cinnamic acid moiety. Two of these Pim-2 inhibitors were synthesized, their potencies against Pim-1 were determined and their cocrystal structures were elucidated in order to determine to what degree the binding modes identified by fragment screening are conserved in optimized inhibitors. The structures show that the cinnamic acid moieties indeed adopt the same binding mode. Fragment screening thus correctly identified binding modes which are maintained when fragments are grown into larger and higher affinity inhibitors. The high-throughput screening-derived compound (E)-3-{3-[6-(4-aminocyclohexylamino)-pyrazin-2-yl]phenyl}acrylic acid (compound 1) is the most potent inhibitor of the cinnamic acid series for which the three-dimensional binding mode is known (IC(50) = 17 nM, K(d) = 28 nM). The structure reveals the molecular basis for the large gain in potency between the initial fragment hit and this optimized inhibitor.

		+	[[http://www.uniprot.org/uniprot/PIM1_HUMAN PIM1_HUMAN]] Proto-oncogene with serine/threonine kinase activity involved in cell survival and cell proliferation and thus providing a selective advantage in tumorigenesis. Exerts its oncogenic activity through: the regulation of MYC transcriptional activity, the regulation of cell cycle progression and by phosphorylation and inhibition of proapoptotic proteins (BAD, MAP3K5, FOXO3). Phosphorylation of MYC leads to an increase of MYC protein stability and thereby an increase of transcriptional activity. The stabilization of MYC exerted by PIM1 might explain partly the strong synergism between these two oncogenes in tumorigenesis. Mediates survival signaling through phosphorylation of BAD, which induces release of the anti-apoptotic protein Bcl-X(L)/BCL2L1. Phosphorylation of MAP3K5, an other proapoptotic protein, by PIM1, significantly decreases MAP3K5 kinase activity and inhibits MAP3K5-mediated phosphorylation of JNK and JNK/p38MAPK subsequently reducing caspase-3 activation and cell apoptosis. Stimulates cell cycle progression at the G1-S and G2-M transitions by phosphorylation of CDC25A and CDC25C. Phosphorylation of CDKN1A, a regulator of cell cycle progression at G1, results in the relocation of CDKN1A to the cytoplasm and enhanced CDKN1A protein stability. Promote cell cycle progression and tumorigenesis by down-regulating expression of a regulator of cell cycle progression, CDKN1B, at both transcriptional and post-translational levels. Phosphorylation of CDKN1B,induces 14-3-3-proteins binding, nuclear export and proteasome-dependent degradation. May affect the structure or silencing of chromatin by phosphorylating HP1 gamma/CBX3. Acts also as a regulator of homing and migration of bone marrow cells involving functional interaction with the CXCL12-CXCR4 signaling axis.<ref>PMID:1825810</ref> <ref>PMID:10664448</ref> <ref>PMID:12431783</ref> <ref>PMID:15528381</ref> <ref>PMID:16356754</ref> <ref>PMID:18593906</ref> <ref>PMID:19749799</ref>

		+	A crystallographic fragment screen was carried out to identify starting points for the development of inhibitors of protein kinase Pim-1, a potential target for tumour therapy. All fragment hits identified via soaking in this study turned out to bind to the unusually hydrophobic pocket at the hinge region. The most potent fragments, two cinnamic acid derivatives (with a best IC(50) of 130 microM), additionally form a well defined hydrogen bond. The balance between hydrophobic and polar interactions makes these molecules good starting points for further optimization. Pim-2 inhibitors from a recently reported high-throughput screening campaign also feature a cinnamic acid moiety. Two of these Pim-2 inhibitors were synthesized, their potencies against Pim-1 were determined and their cocrystal structures were elucidated in order to determine to what degree the binding modes identified by fragment screening are conserved in optimized inhibitors. The structures show that the cinnamic acid moieties indeed adopt the same binding mode. Fragment screening thus correctly identified binding modes which are maintained when fragments are grown into larger and higher affinity inhibitors. The high-throughput screening-derived compound (E)-3-{3-[6-(4-aminocyclohexylamino)-pyrazin-2-yl]phenyl}acrylic acid (compound 1) is the most potent inhibitor of the cinnamic acid series for which the three-dimensional binding mode is known (IC(50) = 17 nM, K(d) = 28 nM). The structure reveals the molecular basis for the large gain in potency between the initial fragment hit and this optimized inhibitor.
