General annotation (Comments)

Function	Dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex and may be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing. Phosphorylates SRSF1 and SRSF3. Required for the regulation of alternative splicing of MAPT/TAU. Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells. Ref.1 Ref.5
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Enzyme regulation	TG003 inhibits its kinase activity and affects the regulation of alternative splicing mediated by phosphorylation of SR proteins. Ref.7
Subunit structure	Interacts with UBL5 By similarity.
Subcellular location	Nucleus Ref.1.
Tissue specificity	Expressed in the hippocampus, the cerebellum and the olfactory bulb. Ref.6
Post-translational modification	Autophosphorylates on all three types of residues.
Sequence similarities	Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. Lammer subfamily. Contains 1 protein kinase domain.
