Protocols

Specificity / Sensitivity

Phospho-Acetyl-CoA Carboxylase (Ser79) (D7D11) Rabbit mAb recognizes endogenous levels of acetyl-CoA carboxylase protein only when phosphorylated at Ser79.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser79 of human acetyl-CoA carboxylase protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from SH-SY5Y cells, untreated or treated with Oligomycin #9996 (0.5 μM, 30 min), using Phospho-Acetyl-CoA Carboxylase (Ser79) (D7D11) Rabbit mAb (upper) or Acetyl-CoA Carboxylase (C83B10) Rabbit mAb #3676 (lower). The phospho-specificity of the antibody was verified by λ phosphatase treatment.

IF-IC

Confocal immunofluorescent analysis of 293 cells (all nutrient-starved with Krebs-Ringer bicarbonate buffer for 4 hr), starved only (top left), serum-treated (10%, 30 min; top right), H2O2-treated (10 mM, 10 min; bottom left), or λ phosphatase-treated (2 hr; bottom right), using Phospho-Acetyl-CoA Carboxylase (Ser79) (D7D11) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Background

Acetyl-CoA carboxylase (ACC) catalyzes the carboxylation of acetyl-CoA to malonyl-CoA (1). It is the key enzyme in the biosynthesis and oxidation of fatty acids (1). In rodents, the 265 kDa ACC1 (ACCα) form is primarily expressed in lipogenic tissues, while 280 kDa ACC2 (ACCβ) is the main isoform in oxidative tissues (1,2). However, in humans, ACC2 is the predominant isoform in both lipogenic and oxidative tissues (1,2). Phosphorylation by AMPK at Ser79 or by PKA at Ser1200 inhibits the enzymatic activity of ACC (3). ACC is a potential target of anti-obesity drugs (4,5).
