CARM1(coactivator-associated arginine methyltransferase 1), also known as PRMT4 (protein arginine N-methyltransferase 4), is anenzyme(EC2.1.1.125) encoded by theCARM1gene found in human beings, as well as many other mammals.[2]It has a polypeptide (L) chain type that is 348 residues long, and is made up of alpha helices and beta sheets.[3]Its main function includes catalyzing the transfer of a methyl group fromS-Adenosyl methionineto the side chain nitrogens ofarginineresidues within proteins to form methylated arginine derivatives andS-Adenosyl-L-homocysteine.[4]CARM1 is a secondarycoactivatorthrough its association with p160 family (SRC-1,GRIP1,AIB) of coactivators. It is responsible for moving cells toward the inner cell mass in developing blastocysts.[5]

Clinical significance

[edit]

CARM1 plays an important role in androgen receptors and may play a role in prostate cancer progression.[6][7]

CARM1 exerts both oncogenic and tumor-suppressive functions. In breast cancer, CARM1 methylateschromatin remodelingfactor BAF155 to enhance tumor progression and metastasis.[8]Inpancreatic cancer,CARM1 methylates and inhibitsMDH1by disrupting its dimerization, which represses mitochondria respiration and inhibits glutamine utilization. CARM1-mediated MDH1 methylation reduces cellularNADPHlevel and sensitizes cells tooxidative stress,thereby suppressing cell proliferation and colony formation.[9]
