Protein arginine N-methyltransferase skb1

Gene

skb1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

S-adenosyl-L-methionine-dependent protein-arginine N-methyltransferase that can catalyze both the mono- and symmetric (type II) dimethylation of the guanidino nitrogens of arginine residues in target proteins (By similarity). Positively modulates the shk1 kinase function. May be a mediator of hyperosmotic stress response (PubMed:11278267).By similarity1 Publication
