The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase was shown to be activated rapidly during Fas-mediated apoptosis in Jurkat cells. In response to Fas receptor ligation, it phosphorylates TIA1, an apoptosis-promoting nuclear RNA-binding protein. The encoded protein is a strong inducer of lymphocyte apoptosis. Two transcript variants encoding different isoforms have been found for this gene. Other variants exist, but their full-length natures have not yet been determined. [provided by RefSeq, Jul 2008]
A study in mice demonstrated that ethanol exposure induces oxidative stress via NADPH oxidase, leading to Regnase-1-mediated degradation of the FASTK mRNA, which in turn represses mitochondrial gene MTND6 and impairs complex I respiration, exacerbating alcoholic cardiomyopathy; cardiomyocyte-specific overexpression of the FASTK via AAV9 mitigated these dysfunctions [Zhang et al. DOI:10.1016/J.Redox.2020.101778].
