FASTK
Phosphorylates the splicing regulator TIA1, thereby promoting the inclusion of FAS exon 6, which leads to an mRNA encoding a pro-apoptotic form of the receptor. Isoform 4: Required for the biogenesis of some mitochondrial-encoded mRNAs, specifically stabilizes ND6 (NADH dehydrogenase complex subunit 6) mRNA, and regulates its levels. Belongs to the FAST protein kinase family. Expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. 4 alternative splicing and alternative initiation human isoforms have been reported. Note: This description may include information from UniProtKB.
