Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is an enzyme of about 37 kDa that catalyzes the sixth step of glycolysis, the conversion of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. In addition to this long established metabolic function, GAPDH has recently been implicated in several non-metabolic processes, including transcription activation, initiation of apoptosis, and ER to Golgi vesicle shuttling [1].
Tri a 34, the GAPDH from wheat, was identified as a minor allergen for patients with baker's asthma [2].
