The function of Ensembl gene identifier ENSG00000111218 (PRMT8, protein arginine methyltransferase 8) is as follows. S-adenosyl-L-methionine-dependent and membrane-associated arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and asymmetrical dimethylarginine (aDMA) in proteins such as NIFK, myelin basic protein, histone H4, H2A and H2A/H2B dimer (PubMed:16051612, PubMed:17925405, PubMed:26529540, PubMed:26876602). Able to mono- and dimethylate EWS protein; however its precise role toward EWS remains unclear as it still interacts with fully methylated EWS (PubMed:18320585). {ECO:0000269|PubMed:16051612, ECO:0000269|PubMed:17925405, ECO:0000269|PubMed:18320585, ECO:0000269|PubMed:26529540, ECO:0000269|PubMed:26876602}.
