Automated description from the Alliance of Genome Resources (Release 5.2.0)
Enables mannosyl-oligosaccharide 1,2-alpha-mannosidase activity. Involved in positive regulation of retrograde protein transport, ER to cytosol and trimming of terminal mannose on C branch. Acts upstream of or within ubiquitin-dependent ERAD pathway. Is integral component of endoplasmic reticulum membrane. Is expressed in embryo and liver. Orthologous to human EDEM1 (ER degradation enhancing alpha-mannosidase like protein 1).
