We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [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> | ||

| + | We describe the discovery of a series of potent, selective, and orally bioavailable bis-acyl hydrazide inhibitors targeting the PRMT5.MTA complex for the treatment of MTAP-deleted cancers. Key to this discovery was the identification of major metabolite M1, resulting from N-demethylation of lead inhibitor compound 12, as a potent hERG inhibitor. Leveraging the kinetic isotope effect, we generated methyl-d(3) analog 16 which reduced the formation of M1 in vivo, resulting in acceptable safety margins and an improved pharmacokinetic profile. Our data suggest this strategy could be employed more broadly to reduce undesirable metabolism of methylated amines. | ||
