產品介紹 :   Loading Control

Glyceraldehyde 3 phosphate dehydrogenase (GAPDH) is well known as one of the key enzymes involved in glycolysis. As well as functioning as a glycolytic enzyme in cytoplasm, recent evidence suggests that mammalian GAPDH is also involved in a great number of intracellular proceses such as membrane fusion, microtubule bundling, phosphotransferase activity, nuclear RNA export, DNA replication, and DNA repair. During the last decade a lot of data appeared concerning the role of GAPDH in different pathologies including prostate cancer progression, programmed neuronal cell death, age related neuronal diseases, such as Alzheimer's and Huntington's disease. GAPDH is expressed in all cells. It is constitutively expressed in almost all tissues at high levels. There are however some physiological factors such as hypoxia and diabetes that increase GAPDH expression in certain cell types. GAPDH molecule is composed of four 36kDa subunits.

Function:

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. 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.

Subunit:

Homotetramer. Interacts with TPPP; the interaction is direct. Interacts (when S-nitrosylated) with SIAH1; leading to nuclear translocation. Interacts with RILPL1/GOSPEL, leading to prevent the interaction between GAPDH and SIAH1 and prevent nuclear translocation. Interacts with EIF1AD, USP25, PRKCI and WARS.

Subcellular Location:

Cytoplasm, cytosol. Nucleus. Cytoplasm, perinuclear region. Membrane. Note=Translocates to the nucleus following S-nitrosylation and interaction with SIAH1, which contains a nuclear localization signal. Postnuclear and

Perinuclear regions.

Post-translational modifications:

S-nitrosylation of Cys-152 leads to interaction with SIAH1, followed by translocation to the nucleus.

ISGylated (Probable).

Sulfhydration at Cys-152 increases catalytic activity.

Similarity:

Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.

GAPDH蛋白幾乎在所有組織中都高水平表達，廣泛用作Western blot蛋白質標準化的內參,是很好的內參抗體。

GAPDH 作為管家基因在同種細胞或者組織中的蛋白質表達量一般是恒定的。在實驗中，可能存在總蛋白濃度測定不準確；或者蛋白質樣品在電泳前上樣時產生的樣品間的操作誤差；這些誤差需要通過測定每個樣品中實際轉到膜上的GAPDH的含量來進行校正，所以一般的western實驗都需要進行內參設置。具體校正的方法就是將每個樣品測得的目的蛋白含量與本樣品的GAPDH含量相除，得到每個樣品目的蛋白的相對含量。然后才進行樣品與樣品之間的比較。

甘油醛-3-磷酸脫氫酶（Glyceraldehyde 3 phosphate dehydrogenase，GAPDH）是糖酵解（glycolysis）過程中的關鍵酶。除了在胞質中作為糖酵解的酶以外，有證據表明哺乳動物細胞中的GAPDH參與了多種胞內生化過程，包括膜融合（membrane fusion）、微管成束（microtubule bundling）、磷酸轉移酶（phosphotransferase）激活、核內RNA出核、DNA復制與DNA修復。一些生理因素，諸如低氧（hypoxia）和尿糖（diabetes），可以增加GAPDH在特定細胞中的表達。GAPDH存在于幾乎所有的組織中，以高水平持續表達。

GAPDH（甘油醛-3-磷酸脫氫酶）是參與糖酵解的一種關鍵酶，由4個30－40kDa的亞基組成.
