Web18 jan. 2024 · Acetylation of K601 stimulates BRAF kinase activity and facilitates melanoma tumorigenesis To further understand the importance of p300-mediated acetylation in BRAF kinase activity, we generated K601Q acetylation mutant to mimic the acetylation on K601 ( Inuzuka et al., 2012 ). Webshowed that the level of acetylation at LEF-11 K83 was significantly down-regulated post-infection, but the un-derlying mechanism remains unknow. In this study, the functional role of LEF-11 acetylation was gained by mutation of lysine residues to glutamine or arginine to mimic acetylation or deacetylation, re-spectively (Choudhary et al., 2009).
