WebPhosphopeptide. 21 Phosphopeptides are separated by affinity chromatography involving antibodies against phosphorylated domains of proteins or by an affinity-based selective … Phosphopeptides are modified self antigens which may induce an immune response. Protein phosphorylation is a very important and frequent post-translational modification that can impact a protein's localization, stability, and whether or not it can dimerize or form stable bonds with other substances. It is vital to pinpoint which amino acid in ...
WebApproaches are described to interpret such neutral loss-dominated spectra to identify the phosphopeptide and localize the phosphorylation site. Methods using additional activation, such as MS(3) and multistage activation (MSA), have been designed to generate more sequence-informative fragments from the ion produced by the neutral loss.
