WebPhosphorylation of amino acid residues in proteins plays a major role in biological systems. Often, phosphorylation acts as a molecular switch controlling the protein activity in … Webphorylation sites, using mutagenesis, phosphoamino acid analysis, and site-specific anti-Stat5-phosphoserine antibodies. Unexpectedly, phosphorylation control of this PSP motif differed between the highly homologous Stat5a and Stat5b proteins. Whereas Ser725 of Stat5a was constitutively phosphorylated both in COS-7 cells and

WebHuman placental Choline Acetyltransferase (ChAT) has been shown to be phosphorylated in vitro by kinases present in rat brain. Phosphorylation occurs at a single site with the exclusive phosphoamino acid being serine. ChAT phosphorylation was shown to be calcium, and not cyclic nucleotide, dependent … WebDec 1, 2003 · Phosphoamino acid analysis was performed as previously described by Besant and Attwood [7]with some modifications. Histone H4 (25 μg) was immunoprecipitated with 10 μg of the monoclonal anti-histone pan antibody (Roche) for 1 h at room temperature. bing legacy countertops

WebMay 1, 2001 · It is often valuable to identify the phosphorylated residue in a protein. In the case of proteins phosphorylated at serine, threonine, or tyrosine, this is readily accomplished by partial acid hydrolysis in HCl followed by two-dimensional thin-layer electrophoresis of the labeled phosphoamino acid, as described here.
