Entrez Gene Summary for STK26 Gene

  • The product of this gene is a member of the GCK group III family of kinases, which are a subset of the Ste20-like kinases. The encoded protein contains an amino-terminal kinase domain, and a carboxy-terminal regulatory domain that mediates homodimerization. The protein kinase localizes to the Golgi apparatus and is specifically activated by binding to the Golgi matrix protein GM130. It is also cleaved by caspase-3 in vitro, and may function in the apoptotic pathway. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

GeneCards Summary for STK26 Gene

STK26 (Serine/Threonine Kinase 26) is a Protein Coding gene. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and LKB1 signaling events. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and transferase activity, transferring phosphorus-containing groups. An important paralog of this gene is STK24.

UniProtKB/Swiss-Prot for STK26 Gene

  • Mediator of cell growth (PubMed:11641781, PubMed:17360971). Modulates apoptosis (PubMed:11641781, PubMed:17360971). In association with STK24 negatively regulates Golgi reorientation in polarized cell migration upon RHO activation (PubMed:27807006).
