WebMdm2 has been identified as a p53 interacting protein that represses p53 transcriptional activity. Mdm2 achieves this repression by binding to and blocking the N-terminal trans-activation domain of p53. Mdm2 is a p53 responsive gene—that is, its transcription can be activated by p53. Web15 mrt. 2024 · This is consistent with structural data suggesting that phosphorylated GPCR elements, as well as IP6, displace the C-terminus of arrestins from its basal conformation (Chen et al., 2024; Shukla et al., ... Ubiquitin ligase parkin promotes Mdm2-arrestin interaction but inhibits arrestin ubiquitination. Biochemistry (2011), pp. 3749-3763.
