Anti-GAPDH Antibody

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a multifunctional protein , that is located on chromosome 12p13. It is basically called as a glycolytic enzyme.

The antibody detects endogenous level of total GAPDH protein.

Has both glyceraldehyde-3-phosphate dehydrogenase and nitrosylase activities, thereby playing a role in glycolysis and nuclear functions, respectively. Participates in nuclear events including transcription, RNA transport, DNA replication and apoptosis. Nuclear functions are probably due to the nitrosylase activity that mediates cysteine S-nitrosylation of nuclear target proteins such as SIRT1, HDAC2 and PRKDC By similarity. Glyceraldehyde-3-phosphate dehydrogenase is a key enzyme in glycolysis that catalyzes the first step of the pathway by converting D-glyceraldehyde 3-phosphate (G3P) into 3-phospho-D-glyceroyl phosphate.

Peptide sequence around aa. 252-256 (P-A-K-Y-D), according to the protein NP_002037.2

Anti-GAPDH antibody has been used in western blotting.{60,61}

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) plays an important role in DNA repair. It is essential for the sixth step of glycolysis. It participates in transcriptional and posttranscriptional gene regulation. It also controls intracellular membrane trafficking and cell death. Accumulation of GAPDH results in mitochondrial dysfunction.
