What is the function of GAPDH?

The canonical enzymatic function of GAPDH is to catalyse the oxidation and phosphorylation of glyceraldehyde-3-phosphate (G3P) to the 1,3-bisphosphoglycerate (1,3 BPG), using NAD+ as a co-substrate.

Is GAPDH a transferase?


Molecular function Oxidoreductase, Transferase
Biological process Apoptosis, Glycolysis, Immunity, Innate immunity, Translation regulation
Ligand NAD

Is GAPDH a kinase?

GAPDH is the GABAAR endogenous kinase.

How does glyceraldehyde 3-phosphate dehydrogenase work?

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a very important enzyme in the production of energy and in photosynthesis. In the production of energy this enzyme catalyzes the sixth step in the process of breaking down glucose, also known as glycolysis which occurs in organisms of all phyla.

What type of protein is GAPDH?

Multifunctional Protein
GAPDH is a Multifunctional Protein GAPDH is one of the enzymes involved in the ubiquitous process of glycolysis. GAPDH specifically catalyzes the simultaneous phosphorylation and oxidation of glyceraldehyde-3-phosphate to 1,3-biphosphoglycerate, using NAD+ as the electron acceptor.

Why GAPDH is used as control?

GAPDH antibody, is usually used as a loading control antibody for Western Blot to normalize the levels of protein detected by confirming that protein loading is the same across the gel.

Does GAPDH have a covalent intermediate?

Here we report the characterization of GAPDH from Mycobacterium tuberculosis (Mtb). This enzyme exhibits a kinetic mechanism in which first NAD+, then G3P bind to the active site resulting in the formation of a covalently bound thiohemiacetal intermediate.

Is glyceraldehyde 3-phosphate a protein?

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) may be considered the quintessential multidimensional protein which exhibits a variety of functions unrelated to its classical role in energy production.

Is GAPDH a good loading control?

GAPDH (36 kDa) is integral for glycolysis and plays many roles in nuclear function; such as transcription regulation and apoptosis. The stable and ubiquitous expression of GAPDH also make it a suitable loading control for many experiments.

Why are controls used in Western blotting?

Loading controls should be used: To check that all lanes in the gel contain the same amount of sample. This gives the researcher confidence that differences in the protein of interest are not due to errors while loading the gel. To measure the amount of protein present in samples.

Why is GAPDH used as control?

What are the functions of the GAPDH gene?

Has both glyceraldehyde-3-phosphate dehydrogenase and nitrosylase activities, thereby playing a role in glycolysis and nuclear functions, respectively (PMID: 3170585, PMID: 11724794 ).

What is the role of GAPDH in energy metabolism?

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has long been recognized as an important enzyme for energy metabolism and the production of ATP and pyruvate through anaerobic glycolysis in the cytoplasm. Recent studies have shown that GAPDH has multiple functions independent of its role in energy metabolism.

How does GAPDH function as a transferrin receptor?

Gapdh is a moonlighting protein that functions as a glycolytic enzyme and a transferrin receptor. Gapdh is a moonlighting protein that functions as a glycolytic enzyme and additionally is involved in regulating mRNA stability.

Why is GAPDH used as a nuclear target?

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). It is to be used only for research and educational purposes.
