描述:
Glyceraldehyde 3 phosphate dehydrogenase (GAPDH) iswell 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 GAPDHis also involved in a great number of intracellular procesessuch as membrane fusion, microtubule bundling, phosphotransferaseactivity, nuclear RNA export, DNA replication,and DNA repair.

研究背景

功能:

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. Modulates the organization and assembly of the cytoskeleton. Facilitates the CHP1-dependent microtubule and membrane associations through its ability to stimulate the binding of CHP1 to microtubules (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. Component of the GAIT (gamma interferon-activated inhibitor of translation) complex which mediates interferon-gamma-induced transcript-selective translation inhibition in inflammation processes. Upon interferon-gamma treatment assembles into the GAIT complex which binds to stem loop-containing GAIT elements in the 3'-UTR of diverse inflammatory mRNAs (such as ceruplasmin) and suppresses their translation.

翻译修饰:

S-nitrosylation of Cys-152 leads to interaction with SIAH1, followed by translocation to the nucleus (By similarity). S-nitrosylation of Cys-247 is induced by interferon-gamma and LDL(ox) implicating the iNOS-S100A8/9 transnitrosylase complex and seems to prevent interaction with phosphorylated RPL13A and to interfere with GAIT complex activity.

ISGylated.

Sulfhydration at Cys-152 increases catalytic activity.

Oxidative stress can promote the formation of high molecular weight disulfide-linked GAPDH aggregates, through a process called nucleocytoplasmic coagulation. Such aggregates can be observed in vivo in the affected tissues of patients with Alzheimer disease or alcoholic liver cirrhosis, or in cell cultures during necrosis. Oxidation at Met-46 may play a pivotal role in the formation of these insoluble structures. This modification has been detected in vitro following treatment with free radical donor (+/-)-(E)-4-ethyl-2-[(E)-hydroxyimino]-5-nitro-3-hexenamide. It has been proposed to destabilize nearby residues, increasing the likelihood of secondary oxidative damages, including oxidation of Tyr-45 and Met-105. This cascade of oxidations may augment GAPDH misfolding, leading to intermolecular disulfide cross-linking and aggregation.

Succination of Cys-152 and Cys-247 by the Krebs cycle intermediate fumarate, which leads to S-(2-succinyl)cysteine residues, inhibits glyceraldehyde-3-phosphate dehydrogenase activity. Fumarate concentration as well as succination of cysteine residues in GAPDH is significantly increased in muscle of diabetic mammals. It was proposed that the S-(2-succinyl)cysteine chemical modification may be a useful biomarker of mitochondrial and oxidative stress in diabetes and that succination of GAPDH and other thiol proteins by fumarate may contribute to the metabolic changes underlying the development of diabetes complications.

亚基结构:

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 CHP1; the interaction increases the binding of CHP1 with microtubules. Associates with microtubules (By similarity). Interacts with EIF1AD, USP25, PRKCI and WARS1. Interacts with phosphorylated RPL13A; inhibited by oxidatively-modified low-densitity lipoprotein (LDL(ox)). Component of the GAIT complex. Interacts with FKBP6; leading to inhibit GAPDH catalytic activity.

蛋白家族:

The [IL]-x-C-x-x-[DE] motif is a proposed target motif for cysteine S-nitrosylation mediated by the iNOS-S100A8/A9 transnitrosylase complex.

Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.

Fig. 5 | CNP increases exosome release through HSP–p53–TASP6 signalling pathway. a, Simulated temperature changes at five selected locations. A 200 V and 10 ms pulse created a localized ‘hot spot’ in the nanochannel outlet with a power density of ~1 × 1014 W m−3 and a peak temperature up to 60 °C from room temperature. Once the pulse ended, the hot spot vanished rapidly due to the extremely small volume of the heated fluid inside the nanochannel (~1 × 10−12 cm3 ) compared with the bulk solution outside the nanochannel (~0.1 cm3 ). b, Top-down images of MEFs (green) attaching to the surface of the CNP device. Red dots show nanochannel locations and room temperature before CNP transfection (0 s). White arrows indicate locations of the nanochannels. The CNP electric pulse (CNP) sharply increases temperature at the nanochannel–cell surface interface. c, Cross-section view of nanochannels shows temperature changes in the nanochannels before (0 s), during and after (1 s) a CNP pulse. d, Temperature at the cell–nanochannel interface transiently (<1 s) increases to ~60 °C. e, Western blot of HSP90 and HSP70 from untreated (PBS) and CNP (with PBS)-stimulated (CNP) MEFs. f, DLS measurements of exosome concentrations from 108 CNP-stimulated MEFs with or without HSP inhibitors show that HSP70 and HSP90 are critical for the production of exosomes. NVP-HSP990, HSP90 inhibitor; VER155008, HSP70 inhibitor. g, Western blots show that CNP increases expression of p53 and TSAP6 protein in p53 wild-type MEFs, but does not affect p53 or TSAP6 protein expression in p53−/− MEFs. h, DLS measurements of exosome concentrations show that knockdown of p53 can partially block exosome release after CNP. i, Schematic of a proposed mechanism for CNP triggering of exosome release in CNP-transfected cells. Data are from three independent experiments and are presented as mean ± s.e.m. Two-sided Student’s t-test was used for the comparison.
