Accession number: NM_002046.The HsGAPDH primers and probe can be used to quantify a control locus in chromatin immunoprecipitation (ChIP) assays with chromatin prepared from human cells. GAPDH (Glyceraldehyde 3-phosphate dehydrogenase) is a highly expressed housekeeping gene. The primers and probe are located in exon 1, within 1 kb of the transcription start site. In most cell types, this locus is highly enriched with histone modifications associated with active gene transcription such as Histone H3 K9 acetylation (see image with ab4441). Whereas it shows low levels of histone modifications associated with silencing such as Histone H3 K9 tri methylation (see image with ab71604).
Has both glyceraldehyde-3-phosphate dehydrogenase and nitrosylase activities, thereby playing a role in glycolysis and nuclear functions, respectively. Participates in nuclear events including transcription, RNA transport, DNA replication and apoptosis. Nuclear functions are probably due to the nitrosylase activity that mediates cysteine S-nitrosylation of nuclear target proteins such as SIRT1, HDAC2 and PRKDC (By similarity). Glyceraldehyde-3-phosphate dehydrogenase is a key enzyme in glycolysis that catalyzes the first step of the pathway by converting D-glyceraldehyde 3-phosphate (G3P) into 3-phospho-D-glyceroyl phosphate.
Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 1/5.
Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.
S-nitrosylation of Cys-152 leads to interaction with SIAH1, followed by translocation to the nucleus. ISGylated.
Cytoplasm > cytosol. Nucleus. Cytoplasm > perinuclear region. Membrane. Translocates to the nucleus following S-nitrosylation and interaction with SIAH1, which contains a nuclear localization signal (By similarity). Postnuclear and Perinuclear regions.
