[C.elegansII] NMK. Encodes glyceraldehyde-3-phosphate-dehydrogenase, major muscle-specific isozyme(GAPDHase-2), expression increases postembryonically .Middle gene in operon between mai-1 and gpd-3. [Barrios et al. 1989; Spieth et al. 1993; HH; BL]
gpd-2 encodes one of four C. elegans glyceraldehyde-3-phosphate dehydrogenases (GAPDHs); by homology, GPD-2 is predicted to reversibly catalyze the oxidation and phosphorylation of glyceraldehyde-3-phosphate to 1,3-diphosphoglycerate during glycolysis; in C. elegans, GPD-2 and GPD-3 constitute the major GAPDH isoenzymes and are expressed at highest levels during postembryonic development, primarily in the actin-containing A and I zones of body-wall muscle; loss of gpd-2 function via RNA-mediated interference (RNAi) does not result in any abnormalities.
Predicted to enable glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity. Predicted to be involved in glycolytic process. Predicted to be located in cytosol. Expressed in several structures, including AB; Psub1; and head. Human ortholog(s) of this gene implicated in Alzheimer's disease and lymphangioleiomyomatosis. Is an ortholog of human GAPDH (glyceraldehyde-3-phosphate dehydrogenase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
