Previous GeneCards Identifiers for TNK2 Gene
This gene encodes a tyrosine kinase that binds Cdc42Hs in its GTP-bound form and inhibits both the intrinsic and GTPase-activating protein (GAP)-stimulated GTPase activity of Cdc42Hs. This binding is mediated by a unique sequence of 47 amino acids C-terminal to an SH3 domain. The protein may be involved in a regulatory mechanism that sustains the GTP-bound active form of Cdc42Hs and which is directly linked to a tyrosine phosphorylation signal transduction pathway. Several alternatively spliced transcript variants have been identified from this gene, but the full-length nature of only two transcript variants has been determined. [provided by RefSeq, Jul 2008]
GeneCards Summary for TNK2 Gene
TNK2 (Tyrosine Kinase, Non-Receptor, 2) is a Protein Coding gene. Diseases associated with TNK2 include infantile-onset mesial temporal lobe epilepsy with severe cognitive regression. Among its related pathways are G-protein signaling_Regulation of CDC42 activity and Actin Nucleation by ARP-WASP Complex. GO annotations related to this gene include protein serine/threonine kinase activity and non-membrane spanning protein tyrosine kinase activity. An important paralog of this gene is TNK1.
UniProtKB/Swiss-Prot for TNK2 Gene
Non-receptor tyrosine-protein and serine/threonine-protein kinase that is implicated in cell spreading and migration, cell survival, cell growth and proliferation. Transduces extracellular signals to cytosolic and nuclear effectors. Phosphorylates AKT1, AR, MCF2, WASL and WWOX. Implicated in trafficking and clathrin-mediated endocytosis through binding to epidermal growth factor receptor (EGFR) and clathrin. Binds to both poly- and mono-ubiquitin and regulates ligand-induced degradation of EGFR, thereby contributing to the accumulation of EGFR at the limiting membrane of early endosomes. Downstream effector of CDC42 which mediates CDC42-dependent cell migration via phosphorylation of BCAR1. May be involved both in adult synaptic function and plasticity and in brain development. Activates AKT1 by phosphorylating it on Tyr-176. Phosphorylates AR on Tyr-267 and Tyr-363 thereby promoting its recruitment to androgen-responsive enhancers (AREs). Phosphorylates WWOX on Tyr-287. Phosphorylates MCF2, thereby enhancing its activity as a guanine nucleotide exchange factor (GEF) toward Rho family proteins. Contributes to the control of AXL receptor levels. Confers metastatic properties on cancer cells and promotes tumor growth by negatively regulating tumor suppressor such as WWOX and positively regulating pro-survival factors such as AKT1 and AR.
