Biochem/physiol Actions

α1,2-Mannosidase IA belongs to the first subgroup out of the three subgroups of class I α1,2-Mannosidases. The first subgroup consists of yeast and human α 1,2-mannosidases of the endoplasmic reticulum that convert Man₉GlcNAc₂ to Man₈GlcNAc₂ isomer B. The second subgroup comprising of mammalian Golgi α1,2-Mannosidases IA, IB, and IC cleave Man₉GlcNAc₂ to Man₅GlcNAc₂ via Man₈GlcNAc₂ isomer A and C. The third subgroup of yeast and mammalian proteins do not show any activity on Man₉GlcNAc₂. Proteins from subgroup 1 and 3 have been implicated in ER quality control and in proteasomal degradation of misfolded glycoproteins. The Golgi mannosidases from the second subgroup may play a role in the ERAD (endoplasmic reticulum-associated degradation) of defective glycoproteins. The three subgroups have been found to pariticipate in the maturation of Asn-linked glycoproteins in the endoplasmic reticulum (ER) and Golgi complex.

General description

α1,2-Mannosidase IA is a type II transmembrane Golgi-resident enzyme that belongs to class I α1,2-Mannosidases (glycosylhydrolase family 47). The highly conserved Class I α1,2-Mannosidases classified into three subgroups according to their enzymatic activities. α1,2-Mannosidase IA is predominantly detected in the juxtanuclear Golgi region. The three subgroups differ in their expression pattern, subcellular localization, and substrate specificity.

Immunogen
