This gene encodes an enzyme that hydrolyzes terminal, non-reducing alpha-D-mannose residues in alpha-D-mannosides. Its activity is necessary for the catabolism of N-linked carbohydrates released during glycoprotein turnover and it is member of family 38 of glycosyl hydrolases.

Summaries for MAN2B1 Gene

Entrez Gene Summary for MAN2B1 Gene

  • This gene encodes an enzyme that hydrolyzes terminal, non-reducing alpha-D-mannose residues in alpha-D-mannosides. Its activity is necessary for the catabolism of N-linked carbohydrates released during glycoprotein turnover and it is member of family 38 of glycosyl hydrolases. The full length protein is processed in two steps. First, a 49 aa leader sequence is cleaved off and the remainder of the protein is processed into 3 peptides of 70 kDa, 42 kDa (D) and 13/15 kDa (E). Next, the 70 kDa peptide is further processed into three peptides (A, B and C). The A, B and C peptides are disulfide-linked. Defects in this gene have been associated with lysosomal alpha-mannosidosis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2010]

GeneCards Summary for MAN2B1 Gene

MAN2B1 (Mannosidase Alpha Class 2B Member 1) is a Protein Coding gene. Diseases associated with MAN2B1 include Mannosidosis, Alpha B, Lysosomal and Alpha-Mannosidosis, Infantile Form. Among its related pathways are Lysosome and Other glycan degradation. Gene Ontology (GO) annotations related to this gene include carbohydrate binding and alpha-mannosidase activity.

UniProtKB/Swiss-Prot Summary for MAN2B1 Gene

  • Necessary for the catabolism of N-linked carbohydrates released during glycoprotein turnover. Cleaves all known types of alpha-mannosidic linkages.

Tocris Summary for MAN2B1 Gene

  • Glycosylases are a group of enzymes that includes glucosidases, mannosidases and heparanases. There are two glucosidase subtypes, both found in the gut. They hydrolyze terminal (1,4)alpha-glucosidic linkages and (1,6)beta-glucosidic linkages, liberating alpha-glucose and beta-glucose.

  • Mannosidosis, alpha B, lysosomal (MANSA) [MIM:248500]: A lysosomal storage disease characterized by accumulation of unbranched oligosaccharide chains. This accumulation is expressed histologically as cytoplasmic vacuolation predominantly in the CNS and parenchymatous organs. Depending on the clinical findings at the age of onset, a severe infantile (type I) and a mild juvenile (type II) form of alpha-mannosidosis are recognized. There is considerable variation in the clinical expression with mental retardation, recurrent infections, impaired hearing and Hurler-like skeletal changes being the most consistent abnormalities. {ECO:0000269 PubMed:12718372, ECO:0000269 PubMed:15712269, ECO:0000269 PubMed:22161967, ECO:0000269 PubMed:9158146, ECO:0000269 PubMed:9758606, ECO:0000269 PubMed:9915946}.
