Store at 4°C; make aliquots to avoid working with a stock. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana, Synechocystis sp. PCC 6803
GAPC1 and GAPC2 encode highly similar cytosolic, NAD-dependent (phosphorylating) glyceraldehyde-3-phosphate dehydrogenases that predominantly localize to the cytoplasm but can relocalize to the nucleus under oxidative or metal stress. The proteins are ~338 amino acids and comprise the conserved N-terminal NAD(P)-binding domain and C-terminal catalytic domain typical of type I GAPDH enzymes, assembling as oligomeric dehydrogenases that drive central carbon metabolism. Catalytically, they convert glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate in glycolysis, with activity dependent on a key active-site cysteine (e.g., Cys149 in GAPC1) that is redox sensitive and can undergo reversible glutathionylation, linking enzyme function to cellular redox state. Beyond housekeeping glycolysis, genetic and cell-biological studies support broader roles in coordinating energy/redox homeostasis and development (including impacts on respiration, reactive oxygen species balance, and fertility/seed phenotypes when GAPC function is reduced) and in stress-responsive signaling, where hydrogen peroxide can promote nuclear accumulation of GAPC1/2 and association with transcriptional regulators to modulate gene expression programs involved in stem cell maintenance under oxidative stress.
