Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity Phospho-BCKDH-E1 alpha (Ser293) (E2V6B) Rabbit Monoclonal Antibody recognizes endogenous levels of BCKDH-E1α protein only when phosphorylated at Ser292 of mature human BCKDH-E1α, Ser293 of mature mouse BCKDH-E1α, or Ser293 of mature rat BCKDH-E1α. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser292 of mature human BCKDH-E1α protein, which corresponds to Ser293 of mature mouse BCKDH-E1α protein and Ser293 of mature rat BCKDH-E1α protein. Background Branched-chain amino acids (BCAAs) leucine, isoleucine, and valine are essential amino acids in mammals, but elevated levels of BCAAs have been implicated in cardiovascular and metabolic disorders (1). The branched-chain α-keto acid dehydrogenase complex (BCKDH) catalyzes the rate-limiting step in the BCAA degradation pathway (2,3). Branched-chain α-keto acid decarboxylase (BCKDH-E1) is one of three enzymatic components in this complex (3). The α subunit of BCKDH-E1 (BCKDH-E1α) is critical for the regulation of BCKDH. Phosphorylation of BCKDH-E1α was shown to play a key role in regulating the enzymatic activity of this complex (3-5). Phosphorylation of BCKDH-E1α at Ser293 inactivates BCKDH (3,4). A significant elevation in plasma BCAA levels was reported to correlate with increased phosphorylation of BCKDH-E1α at Ser293 and suppressed BCKDH activity in the liver of diabetic mice (5).
