RC TISSUE=Brain, and Eye; RX MEDLINE=20493536; PubMed=10915796; DOI=10.1074/jbc.M004935200; RA Tremblay L.O., Herscovics A.; RT "Characterization of a cDNA encoding a novel human Golgi alpha 1,2- RT mannosidase involved in N-glycan biosynthesis."; RL J. Biol. Chem. 275:31655-31660(2000). RN [2] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RG Human chromosome 1 international sequencing consortium; RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Involved in the maturation of Asn-linked CC oligosaccharides. Trim alpha-1,2-linked mannose residues from CC Man(9)GlcNAc(2) to produce first Man(8)GlcNAc(2) then Man(6)GlcNAc CC and a small amount of Man(5)GlcNAc. CC -!- CATALYTIC ACTIVITY: Hydrolysis of the terminal 1,2-linked alpha-D- CC mannose residues in the oligo-mannose oligosaccharide CC Man(9)(GlcNAc)(2). CC -!- COFACTOR: Calcium. CC -!- ENZYME REGULATION: Inhibited by both 1-deoxymannojirimycin and CC kifunensine. CC -!- PATHWAY: N-glycosylation. CC -!- SUBCELLULAR LOCATION: Type II membrane protein. Golgi. CC -!- TISSUE SPECIFICITY: Expressed in most tissues with the exception CC of lung, muscle and pancreas. Highly expressed in placenta. CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 47 family.
