Such ubiquitination … Webb1 apr. 2024 · A direct effect of Nt-acetylation on p16 stability was supported by studies in NatB-deficient cells. Together, our studies argue that Nt-acetylation can stabilize proteins in human cells in a substrate-specific manner, by competition with N-terminal ubiquitination, but also by other mechanisms that are independent of protein …
WebbImmunomodulators (IMiDs) exhibit antitoxic effects by binding to cereblon, a key protein of the E3 ubiquitin ligase complex, resulting in rapid ubiquitination and subsequent degradation of transcription factors, IKZF3 and IKZF1, as shown in Figure 1. 43 Immunomodulators also regulate cell adhesion and bone marrow angiogenesis by … WebbUbiquitination is a reversible process due to the presence of deubiquitinating enzymes that can cleave ubiquitin from modified proteins. Posttranslational modification of cell proteins, including ubiquitination, is involved in the regulation of both membrane trafficking and protein degradation.
