EDEM2 (ER Degradation Enhancer, Mannosidase Alpha-Like 2) is a key protein involved in endoplasmic reticulum-associated degradation (ERAD). EDEM2 helps extract misfolded proteins from the ER for degradation by the proteasome.
EDEM2 encodes a member of the mannosidase family involved in endoplasmic reticulum-associated degradation (ERAD). EDEM2 accelerates the degradation of misfolded glycoproteins by recognizing and cleaving mannose residues from the N-glycans of misfolded proteins, targeting them for retrotranslocation to the cytosol and proteasomal degradation. It plays a critical role in ER quality control.
In neurons, EDEM2 helps maintain proteostasis by degrading misfolded proteins that accumulate in various neurodegenerative diseases. It is upregulated under conditions of ER stress.
Expressed in various tissues including brain. Expression is upregulated by ER stress and the unfolded protein response (UPR).
| Disease | Mechanism |
|---|---|
| Congenital Disorder of Glycosylation | Impaired glycoprotein processing |
| Neurodegeneration | Impaired ERAD, accumulation of misfolded proteins |
