Preferred Label : PRMT5 Inhibitor PRT811;
NCIt synonyms : Protein Arginine Methyltransferase 5 Inhibitor PRT811;
NCIt definition : An orally available small molecule inhibitor of protein arginine methyltransferase
5 (PRMT5), with potential antiproliferative and antineoplastic activities. Upon oral
administration, PRMT5 inhibitor PRT811 selectively binds to PRMT5 and inhibits its
function. By inhibiting its methyltransferase activity, levels of both monomethylated
and dimethylated arginine residues in histones H2A, H3 and H4 are decreased. This
modulates the expression of genes involved in several cellular processes, including
cellular proliferation. This may increase the expression of antiproliferative genes
and/or decrease the expression of genes that promote cell proliferation, which may
lead to decreased growth of rapidly proliferating cells, including cancer cells. PRMT5,
a type II methyltransferase that catalyzes the formation of both omega-N monomethylarginine
(MMA) and symmetric dimethylarginine (sDMA) on histones and a variety of other protein
substrates involved in signal transduction and cellular transcription, is overexpressed
in several neoplasms. Elevated levels are associated with decreased patient survival.;
