General annotation (Comments)

Function

Involved in glycoprotein quality control as it is important for the targeting of misfolded glycoproteins for degradation. It trims a single alpha-1,2-linked mannose residue from Man9GlcNAc2 to produce Man8GlcNAc2 with low efficiency. Ref.2

Catalytic activity

Hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in the oligo-mannose oligosaccharide Man9(GlcNAc)2. Ref.2

Cofactor

Calcium By similarity.

Enzyme regulation

Inhibited by kifunensine. Ref.2

Pathway

Protein modification; protein glycosylation.

Subcellular location

Membrane; Single-pass type II membrane protein Potential.

Sequence similarities

Belongs to the glycosyl hydrolase 47 family.
