SRPK2 Proteins and Enzymes

Serine/arginine rich protein-specific kinase 2 (SRPK2) phosphorylates RS domain-containing proteins, such as SFRS1 and SFRS2 on serine residues. SRPK2 plays a role in spliceosome assembly and in mediating the trafficking of splicing factors. SRPK2 also appears to mediate HBV core protein phosphorylation which is a prerequisite for pregenomic RNA encapsidation into viral capsids.
