WebAug 7, 2024 · Background C-terminal Src kinase (Csk) and Csk-homologous kinase (Chk) are the major endogenous inhibitors of Src-family kinases (SFKs). They employ two mechanisms to inhibit SFKs. First, they phosphorylate the C-terminal tail tyrosine which stabilizes SFKs in a closed inactive conformation by engaging the SH2 domain in cis. … Webkinase Csk. Csk is a major negative regulator of SFKs. Using a PP1-analog-sensitive Csk (CskAS) system, we have previously shown that inhibition of CskAS increases SFK …
