CC -!- FUNCTION: PHOSPHORYLATES SERINE- AND ARGININE-RICH (SR) PROTEINS CC OF THE SPLICEOSOMAL COMPLEX MAY BE A CONSTITUENT OF A NETWORK OF CC REGULATORY MECHANISMS THAT ENABLE SR PROTEINS TO CONTROL RNA CC SPLICING. PHOSPHORYLATES SERINES, THREONINES AND TYROSINES (BY CC SIMILARITY). CC -!- SUBCELLULAR LOCATION: NUCLEAR. CC -!- ALTERNATIVE PRODUCTS: 2 ISOFORMS; A LONG FORM (SHOWN HERE) AND A CC SHORT FORM; ARE PRODUCED BY ALTERNATIVE SPLICING. THE SHORT FORM CC LACK THE KINASE DOMAIN. CC -!- PTM: AUTOPHOSPHORYLATES ON ALL THREE TYPE OF RESIDUES (BY CC SIMILARITY). CC -!- SIMILARITY: BELONGS TO THE SER/THR FAMILY OF PROTEIN KINASES. CC LAMMER SUBFAMILY.
