ER degradation-enhancing alpha-mannosidase-like protein 3
Definition:
Involved in endoplasmic reticulum-associated degradation (ERAD). Accelerates the glycoprotein ERAD by proteasomes, by catalyzing mannose trimming from Man8GlcNAc2 to Man7GlcNAc2 in the N-glycans. May also participate in mannose trimming from all glycoproteins and not just misfolded ones targeted to ERAD. May have alpha 1,2-mannosidase activity (By similarity).
