Catalytic activity:ATP + a protein = ADP + a phosphoprotein.,Function:Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex may be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing. Phosphorylates serines, threonines and tyrosines. Required for the regulation of alternative splicing of MAPT/TAU.,PTM:Autophosphorylates on all three types of residues.,similarity:Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. Lammer subfamily.,similarity:Contains 1 protein kinase domain.,subunit:Interacts with UBL5.,tissue specificity:Expressed in liver, kidney, heart, muscle and brain.,
