A, D, G, J	PF05185	PRMT5 arginine-N-methyltransferase (PRMT5)	PRMT5 arginine-N-methyltransferase	The human homologue of yeast Skb1 (Shk1 kinase-binding protein 1) is PRMT5, an arginine-N-methyltransferase [3][4]. These proteins appear to be key mitotic regulators. They play a role in Jak signalling in higher eukaryotes.	Domain
