General description

ER degradation-enhancing α-mannosidase-like 2 is an enzyme encoded by the EDEM2 gene in humans. EDEM2 is localized to the endoplasmic reticulum (ER) mainly as a soluble glycoprotein. It is an enzyme encoded by the EDEM2 gene in humans. It is one of the ER-stress-induced members of the glycosyl hydrolase 47 family.

Immunogen

synthetic peptide corresponding to amino acids 22-38 of human EDEM2, conjugated to KLH. The corresponding sequence differs by one amino acid in mouse and 2 amino acids in rat EDEM2.

Application

Anti-EDEM2 (N-terminal) antibody produced in rabbit is suitable for indirect immunofluorescence at a concentration of 5-10μg/mL using mouse 3T3 cells and western blotting at a concentration of 0.5-1μg/mL using whole extracts of HEK-293T cells expressing recombinant human EDEM2.

Biochem/physiol Actions

Overexpression of ER degradation-enhancing alphamannosidase-like protein 2 (EDEM2) accelerates ER associated degradation (ERAD) by promoting the release of terminally misfolded glycoproteins from the calnexin cycle, without affecting the rate of degradation of nonglycosylated polypeptides or the maturation of model secretory proteins.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

In the endoplasmic reticulum (ER), misfolded proteins are retrotranslocated to the cytosol and degraded by the proteasome in a process known as ER-associated degradation (ERAD). Early in this pathway, a proposed lumenal ER lectin, EDEM, recognizes misfolded glycoproteins in the

Proteins synthesized in the endoplasmic reticulum (ER) lumen are exposed to several dedicated chaperones and folding factors that ensure efficient maturation. Nevertheless, protein folding remains error-prone and mutations in the polypeptide sequence may significantly reduce folding-efficiency. Folding-incompetent proteins carrying N-glycans
Silvia Olivari et al.
The Journal of biological chemistry, 280(4), 2424-2428 (2004-12-08)
Proteins expressed in the endoplasmic reticulum (ER) are subjected to a tight quality control. Persistent association with ER-resident molecular chaperones prevents exit of misfolded or incompletely assembled polypeptides from the ER and forward transport along the secretory line. ER-associated degradation
