Bim phosphorylation review
WebBcl-2 family protein activity is often regulated through phosphorylation. Phosphorylation of Bad prevents interaction between Bad and anti-apoptotic Bcl-2 and Bcl-xL proteins. Pro-apoptotic Bim phosphorylation results in ubiquitin-mediated degradation of Bim and decreased inhibition of anti-apoptotic Bcl-2 and Bcl-xL proteins. WebSep 9, 2013 · A JNK-phosphorylation site (T112) has been identified previously in Bim, but a knock-in mouse where this site had been mutated had only very modest changes in apoptosis. 11
