Fas-activated serine/threonine kinase

In enzymology, a Fas-activated serine/threonine kinase is an enzyme that catalyzes the chemical reaction


 * ATP + [Fas-activated serine/threonine protein] $$\rightleftharpoons$$ ADP + [Fas-activated serine/threonine phosphoprotein]

Thus, the two substrates of this enzyme are ATP and [Fas-activated serine/threonine protein], whereas its two products are ADP and [Fas-activated serine/threonine phosphoprotein].

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups protein-serine/threonine kinases. The systematic name of this enzyme class is ATP:[Fas-activated serine/threonine protein] phosphotransferase. Other names in common use include FAST, FASTK, and STK10.
