Summaries for FRK Gene

Entrez Gene Summary for FRK Gene

  • The protein encoded by this gene belongs to the TYR family of protein kinases. This tyrosine kinase is a nuclear protein and may function during G1 and S phase of the cell cycle and suppress growth. [provided by RefSeq, Jul 2008]

GeneCards Summary for FRK Gene

FRK (Fyn-Related Src Family Tyrosine Kinase) is a Protein Coding gene. GO annotations related to this gene include non-membrane spanning protein tyrosine kinase activity. An important paralog of this gene is ABL2.

UniProtKB/Swiss-Prot for FRK Gene

  • Non-receptor tyrosine-protein kinase that negatively regulates cell proliferation. Positively regulates PTEN protein stability through phosphorylation of PTEN on Tyr-336, which in turn prevents its ubiquitination and degradation, possibly by reducing its binding to NEDD4. May function as a tumor suppressor.
