GN SYK. OS Rattus norvegicus (Rat). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Rodentia; Sciurognathi; Muridae; Murinae; Rattus. OX NCBI_TaxID=10116; RN [1] RP SEQUENCE FROM N.A. RX MEDLINE=95279402; PubMed=7759516; RA Rowley R.B., Bolen J.B., Fargnoli J.; RT "Molecular cloning of rodent p72Syk. Evidence of alternative mRNA RT splicing."; RL J. Biol. Chem. 270:12659-12664(1995). CC -!- FUNCTION: MAY PARTICIPATE IN SIGNALING PATHWAYS. PLAYS A ROLE IN CC LYMPHOCYTE ACTIVATION. CC -!- CATALYTIC ACTIVITY: ATP + a protein tyrosine = ADP + protein CC tyrosine phosphate. CC -!- ALTERNATIVE PRODUCTS: 2 ISOFORMS; SYKA AND SYKB (SHOWN HERE); CC ARE PRODUCED BY ALTERNATIVE SPLICING. CC -!- PTM: AUTOPHOSPHORYLATED (BY SIMILARITY). CC -!- SIMILARITY: CONTAINS 2 SH2 DOMAINS. CC -!- SIMILARITY: TO OTHER PROTEIN-TYROSINE KINASES IN THE CATALYTIC CC DOMAIN. BELONGS TO THE SYK/ZAP-70 SUBFAMILY.
