Cytoplasmic p53
WebIntroduction. TP53 is possibly the most frequently altered gene in human cancers (Kandoth et al., 2013).The encoded p53 protein is a powerful tumor suppressor, and its loss-of-function is associated with cancer development and progression (Levine, 2024).Intriguingly, the majority of TP53 mutations are missense, encoding full-length proteins (mutp53) that … WebFeb 27, 2001 · Previous studies have shown that nuclear p53 over-expression is an indicator of p53 mutations whereas cytoplasmic p53 accumulation is related to wild-type p53 in several kinds of tumors. Cytoplasmic p53 accumulation has been demonstrated to be an independent prognostic factor in colorectal adenocarcinomas.

Methods Cultured mouse MAECs were exposed to heat stress induced by incubation at 43 ℃ for 2 h, with the cells in routine culture condition (37 ℃, 5% CO2) as the control group. WebCytoplasmic p53 associates with the microtubule cytoskeleton and the dynein family of motor proteins; while Parc and mot2 are involved in its cytoplasmic sequestration. Finally, a portion of p53 is localized to the mitochondria as part of the non-transcriptional apoptotic response. In this review we strive to present the most recent data on how ...
WebJan 9, 2024 · To identify novel proteins that interact with the fragile X mental retardation protein (FMRP), encoded by the FMR1 gene (), Schenck et al.

WebHAUSP is a nuclear ubiquitin-specific protease that targets p53 and Mdm2 proteins as substrates and, in parallel with Mdm2, has a vital role in p53 functionality . The cytoplasmic accumulation of HAUSP allows HAUSP-p53 interaction and leads to a more steady cytoplasmic p53 form, thus, controlling the apoptotic response through this molecule .
