Summaries for MAN1A1 Gene

Entrez Gene Summary for MAN1A1 Gene

  • This gene encodes a class I mammalian Golgi 1,2-mannosidase which is a type II transmembrane protein. This protein catalyzes the hydrolysis of three terminal mannose residues from peptide-bound Man(9)-GlcNAc(2) oligosaccharides and belongs to family 47 of glycosyl hydrolases. [provided by RefSeq, Jul 2012]

GeneCards Summary for MAN1A1 Gene

MAN1A1 (Mannosidase Alpha Class 1A Member 1) is a Protein Coding gene. Among its related pathways are Transport to the Golgi and subsequent modification and Vesicle-mediated transport. GO annotations related to this gene include calcium ion binding and mannosidase activity. An important paralog of this gene is MAN1A2.

UniProtKB/Swiss-Prot for MAN1A1 Gene

  • Involved in the maturation of Asn-linked oligosaccharides. Progressively trim alpha-1,2-linked mannose residues from Man(9)GlcNAc(2) to produce Man(5)GlcNAc(2).
