Bim phosphorylation
WebOct 14, 2004 · It has been shown that BIM phosphorylation can promote the degradation of BIM through the proteasome pathway (15, 19). However, in this IL-3-dependent cell, substantial amounts of BIM protein persist after its phosphorylation. Perhaps phosphorylated BIM, which cannot interact with BAX, can also be degraded, providing … WebMay 24, 2024 · This is followed by the p53-dependent up-regulation of the pro-apoptotic Bcl2 family molecules, including the BH3-only molecules PUMA, Noxa, and Bim, leading to mitochondrial outer membrane permeabilization (MOMP) and the release of cytochrome c, which activates caspase-dependent apoptosis. miR-23a-3p, a negative regulator of …

WebJan 5, 2024 · Phosphorylation of BIM EL by ERK1/2 at S69 in human or at S65 in mice leads to ubiquitin-proteasome-mediated degradation of BIM EL [15, 16, 48]. Our results showed that although As 2 O 3 activated ERK1/2, JNK and p38 MAPK pathways in BEAS-2B cells, BIM EL degradation was only related to ERK1/2 MAPK pathway, but not JNK … WebJun 29, 2007 · Loss of Bim phosphorylation did not appear to be due to a reduction in ERK activity, because Western blot analysis of extracts from MCF-7 cells undergoing ER stress-induced apoptosis found no decrease in ERK phosphorylation . Upon treatment of MCF-7 cells with thapsigargin, Bad, another BH3-only protein that can be regulated by …
WebOct 14, 2004 · Bim has been shown to be a phosphoprotein in various cellular settings (15, 30–32, 35–38), and while this article was in preparation, several groups reported that phosphorylation of BimEL on Ser 69 by activation of the MEK-ERK pathway promotes its proteasome-mediated degradation (28, 29, 32, 33, 36). Our results are in accord with … WebFeb 16, 2012 · BIM phosphorylation was dependent on MEK1/2 kinase activity, and we identified BIM(EL) serine 69, previously linked to pro-survival responses, as the major site of phosphorylation in CLL and in Ramos cells. BIM(EL)/BIM(L) phosphorylation was associated with release of the pro-survival protein MCL1.
