背景 | GAPDH-2 (Glyceraldehyde-3-phosphate dehydrogenase 2; also GAPD2 and GAPDS) is a 40-44 kDa member of the GAPDH family of enzymes. Due to a high incidence of proline residues, it may migrate anomalously at 56 kDa in SDS-PAGE. GAPDH-2 is expressed only in testis as a homotetramer, where it is found in the cytoplasm bound to the sperm fibrous sheath. Unlike GAPDH that has multiple functions, GAPDH-2 appears to participate only in carbohydrate metabolism, generating energy via glycolysis for sperm motility and fertility. Human GAPDH-2 is 408 amino acids (aa) in length. There are two NAD binding sites (Asp106 and Asn388) with a catalytic region between aa 223-226. One splice variant shows a nine aa insertion after Ser220. Over aa 75-222, human GAPDH-2 shares 84% aa identity with mouse GAPDH-2. |

Detection of Human GAPDH‑2 by Western Blot. Western blot shows lysates of human testis tissue. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human GAPDH‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6276) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for GAPDH‑2 at approximately 56 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
GAPDH‑2 in Human Testes. GAPDH‑2 was detected in immersion fixed paraffin-embedded sections of human testes using Goat Anti-Human GAPDH‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6276) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of sperm cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections. |
