| Product description |
catalytic activity:ATP + a protein = ADP + a phosphoprotein. cofactor:Magnesium. enzyme regulation:Activated by phosphorylation on Ser-52 and Ser-588. Phosphorylates RS domain-containing proteins, such as SFRS1 and SFRS2 on serine residues. Role in spliceosome assembly and in mediating the trafficking of splicing factors. Appears to mediate HBV core protein phosphorylation which is a prerequisite for pregenomic RNA encapsidation into viral capsids. sequence caution:The cDNA appears to contain a duplicated region. Belongs to the protein kinase superfamily. Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. Contains 1 protein kinase domain. tissue specificity:Highly expressed in brain, moderately expressed in heart and skeletal muscle and at low levels in lung, liver, and kidney. |
