Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a metabolic enzyme responsible for catalyzing one step in the glycolytic pathway, the reversible oxidative phosphorylation of glyceraldehyde 3-phosphate to produce glyceraldehyde 1-3-bisphosphate. Because GAPDH protein is expressed in large amounts and is required at all times for an important “house keeping” function, levels of GAPDH mRNA are often measured and used as standards in studies of the expression of other mRNAs. Similarly specific antibodies to GAPDH are used to measure GAPDH expression as a protein standard in western blotting experiments, allowing comparison between the level of this protein and others in a cell or tissue. Apart from a role in glycolysis, GAPDH may have other roles, such as in the activation of transcription (1), and binds to a variety of other proteins, including the amyloid precursor protein, the polyglutamine tracts of Huntingtin (2,3). The protein may also have a role in the regulation of apoptosis, and interestingly migrates from the cytoplasm into the nucleus when cells become apoptotic (4). The control of this is mediated by NO mediated S-nitrosylation of GAPDH in the cytoplasm which then binds to and stabilizes the Siah1 E3 ubiquitin ligase which enters the nucleus along with nitrosylated GAPDH and initiates specific protein degradation events leading to the activation of a nuclear cell death pathway (5). Recently GAPDH was shown to be a substrate for the 5′-AMP dependent protein kinase which results in the redistribution of cellular GAPDH to cytosolic membranes and the inhibition of intracellular transport, a component of the cellular response to starvation (6).
The MCA-1D4 antibody was raised against extensively purified pig GAPDH. The antibody has been widely used as a western blotting standard by many labs for many years and is known to detect GAPDH in a variety of mammalian species including human, rat and mouse. Current data suggests that the epitope for the antibody is within the peptide KYDDIKKVVKQASEGPLKGI, amino acids 254-273 of the human sequence, a peptide which is highly conserved across mammalian species. The antibody produces a single clean band on western blots of typical cell and tissue extracts. We also market a widely used rabbit polyclonal antibody to GAPDH, RPCA-GAPDH with similar properties to MCA-1D4. Mouse select image at left for larger view.
This antibody has been widely used for many years as it has been marketed through several OEM partners of EnCor. Since we have sold a large amount of this antibody directly to researchers, several publications cite out company as the source of this antibody, see CiteAb citations for EnCor MCA-1D4.
Some idea of how widely used is this antibody can be obtained from a Google Scholar search for peer-reviewed publications in which it was used.
