Synthesized phospho-peptide around the phosphorylation site of human PKAα cat (phospho Ser338)

Phospho-PKAα cat (S338) Polyclonal Antibody detects endogenous levels of PKAα cat protein only when phosphorylated at S338.The name of modified sites may be influenced by many factors, such as species (the modified site was not originally found in human samples) and the change of protein sequence (the previous protein sequence is incomplete, and the protein sequence may be prolonged with the development of protein sequencing technology). When naming, we will use the "numbers" in historical reference to keep the sites consistent with the reports. The antibody binds to the following modification sequence (lowercase letters are modification sites):RVsIN

PKA C-alpha

This gene encodes one of the catalytic subunits of protein kinase A , which exists as a tetrameric holoenzyme with two regulatory subunits and two catalytic subunits , in its inactive form. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits have been identified in humans. cAMP-dependent phosphorylation of proteins by protein kinase A is important to many cellular processes , including differentiation , proliferation , and apoptosis. Constitutive activation of this gene caused either by somatic mutations , or genomic duplications of regions that include this gene , have been associated with hyperplasias and adenomas of the adrenal cortex and are linked to corticotropin-independent Cushing's syndrome.
