Rpb1 phosphorylation
WebMay 8, 2014 · Cytoplasmic and nucleoplasmic Rpb1 was phosphorylated exclusively on Tyr1, and phosphorylation specifically of Tyr1 prevented CTD degradation by the proteasome in vitro. Tyr1 phosphorylation was also detected on chromatin-associated, hyperphosphorylated Rpb1, consistent with a role in transcription. WebJan 1, 2013 · Phosphorylation of CTD-Tyr1 was described for human RNAPII almost two decades ago [123], but it was unknown whether this modification is present in other …

WebPhospho-Rpb1 CTD antibody specificity is demonstrated using peptide dot blot. Antibody binding to pre-coated Rpb1 CTD peptides is shown using Phospho-Rpb1 CTD (Ser2) Antibody #8798, Phospho-Rpb1 CTD (Ser5) Antibody #8807, a phospho-Rpb1 CTD (Ser7) antibody, and Phospho-Rpb1 CTD (Ser2/Ser5) Antibody (IP Preferred) #8860. WebConstitutive phosphorylation was therefore investigated as a mechanism of pRb inactivation in bladder tumours. Of 28 bladder tumours examined, western blotting demonstrated pRb …
WebMore specifically, based on our work, we propose that Rpb4 is subject to phosphorylation with a regulatory role in gene expression. Up to the date, only the carboxyl-terminal domain (CTD) of Rpb1, the largest subunit of the RNAPII, has been shown to be phosphorylated with a key role in gene expression regulation [4]. WebThermo Scientific Pierce and Novex phospho-specific kits have been designed to enable specific detection of phosphorylation, offer great specificity and correlate well to western blot data. Figure 1. Scheme of a typical phospho-specific protocol. Our ready-to-use Phospho-specific ELISA kits come with standard, detection antibody, HRP conjugate ...
