The function of ENSG00000141744 (PNMT, phenylethanolamine N-methyltransferase) is as follows. Catalyzes the transmethylation of nonepinephrine (noradrenaline) to form epinephrine (adrenaline), using S-adenosyl-L- methionine as the methyl donor (PubMed:20496117). Other substrates include phenylethanolamine and octopamine (PubMed:16277617, PubMed:16363801, PubMed:8812853). Also methylates normetanephrine (By similarity). {ECO:0000250|UniProtKB:P10937, ECO:0000269|PubMed:16277617, ECO:0000269|PubMed:16363801, ECO:0000269|PubMed:20496117, ECO:0000269|PubMed:8812853}.
