GAPC — Arabidopsis thaliana

Summary

AT3G04120 (GAPC1, GAPC) on Arabidopsis thaliana chromosome 3 encodes a glyceraldehyde-3-phosphate dehydrogenase C subunit, a protein with glyceraldehyde-3-phosphate dehydrogenase domains and NAD(P)-binding domains. It is annotated with glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity, glyceraldehyde-3-phosphate dehydrogenase (NADP) activity, fructose-bisphosphate aldolase activity, phospholipase D activity, voltage-gated monoatomic anion channel activity, and histone acetyltransferase activity. The gene is associated with cytosolic glycolysis, gluconeogenesis, the pentose-phosphate shunt, aerobic respiration, redox signal response, S-nitrosylation, phosphatidic acid metabolism, MVB formation, and response to anoxia. It localizes to the plasma membrane, cell wall, apoplast, vacuole, nucleolus, mitochondrial envelope, and chloroplast envelope. GAPC1 is linked to numerous agronomic traits including grain yield, seed size, starch and sugar content, photosynthetic rate, stomatal resistance, drought and salinity tolerance, freezing tolerance, UV-B sensitivity, lignin content, iron concentration, nitrate transport, stem thickness, and senescence.
