[https://www.uniprot.org/uniprot/ANM5_HUMAN ANM5_HUMAN] Arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and symmetrical dimethylarginine (sDMA), with a preference for the formation of MMA. Specifically mediates the symmetrical dimethylation of arginine residues in the small nuclear ribonucleoproteins Sm D1 (SNRPD1) and Sm D3 (SNRPD3); such methylation being required for the assembly and biogenesis of snRNP core particles. Methylates SUPT5H. Mono- and dimethylates arginine residues of myelin basic protein (MBP) in vitro. Plays a role in the assembly of snRNP core particles. May play a role in cytokine-activated transduction pathways. Negatively regulates cyclin E1 promoter activity and cellular proliferation. May regulate the SUPT5H transcriptional elongation properties. May be part of a pathway that is connected to a chloride current, possibly through cytoskeletal rearrangement. Methylates histone H2A and H4 'Arg-3' during germ cell development. Methylates histone H3 'Arg-8', which may repress transcription. Methylates the Piwi proteins (PIWIL1, PIWIL2 and PIWIL4), methylation of Piwi proteins being required for the interaction with Tudor domain-containing proteins and subsequent localization to the meiotic nuage. Methylates RPS10. Attenuates EGF signaling through the MAPK1/MAPK3 pathway acting at 2 levels. First, monomethylates EGFR; this enhances EGFR 'Tyr-1197' phosphorylation and PTPN6 recruitment, eventually leading to reduced SOS1 phosphorylation. Second, methylates RAF1 and probably BRAF, hence destabilizing these 2 signaling proteins and reducing their catalytic activity. Required for induction of E-selectin and VCAM-1, on the endothelial cells surface at sites of inflammation. Methylates HOXA9. Methylates and regulates SRGAP2 which is involved in cell migration and differentiation. Acts as a transcriptional corepressor in CRY1-mediated repression of the core circadian component PER1 by regulating the H4R3 dimethylation at the PER1 promoter.<ref>PMID:10531356</ref> <ref>PMID:11152681</ref> <ref>PMID:11747828</ref> <ref>PMID:12411503</ref> <ref>PMID:15737618</ref> <ref>PMID:17709427</ref> <ref>PMID:20159986</ref> <ref>PMID:20810653</ref> <ref>PMID:21258366</ref> <ref>PMID:21917714</ref> <ref>PMID:22269951</ref>

== Publication Abstract from PubMed ==
 +
Inhibition of the methyltransferase enzyme PRMT5 by MTA accumulation is a vulnerability of MTAP-deleted cancers. Herein, we report the discovery and optimization of a quinolin-2-amine DEL hit that cooperatively binds PRMT5:MEP50 and MTA to generate a catalytically inhibited ternary complex. X-ray crystallography confirms quinolin-2-amine binding of PRMT5 glutamate-444, while simultaneously exhibiting a hydrophobic interaction with MTA. Lead optimization produced AM-9747, which selectively inhibits PRMT5-directed symmetric dimethylation of arginine residues of proteins, leading to a potent reduction of cell viability in MTAP-del cells compared to MTAP-WT cells. Once-daily oral dosing of AM-9747 in mouse xenografts is well tolerated, displaying a robust and dose-dependent inhibition of symmetric dimethylation of arginine in MTAP-del tumor-xenografts and significant concomitant tumor growth inhibition without any significant effect on MTAP-WT tumor xenografts.
