PTK2B - protein tyrosine kinase 2 beta Gene
Also Known as PKB; PTK; CAKB; FAK2; PYK2; CADTK; FADK2; RAFTK
Species: Homo sapiens
About PTK2B
This gene has 17 transcripts (splice variants), 269 orthologues and 32 paralogues. Broad expression in lymph node (RPKM 29.2), bone marrow (RPKM 29.0) and 24 other tissues.
Summary
This gene encodes a cytoplasmic protein tyrosine kinase which is involved in calcium-induced regulation of ion channels and activation of the map kinase signaling pathway. The encoded protein may represent an important signaling intermediate between neuropeptide-activated receptors or neurotransmitters that increase calcium flux and the downstream signals that regulate neuronal activity. The encoded protein undergoes rapid tyrosine phosphorylation and activation in response to increases in the intracellular calcium concentration, nicotinic acetylcholine receptor activation, membrane depolarization, or protein kinase C activation. This protein has been shown to bind CRK-associated substrate, nephrocystin, GTPase regulator associated with FAK, and the SH2 domain of GRB2. The encoded protein is a member of the FAK subfamily of Protein Tyrosine Kinases but lacks significant sequence similarity to kinases from Other subfamilies. Four transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
