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 Innate Immune System and Other glycan degradation. Gene Ontology (GO) annotations related to this gene include carbohydrate binding and alpha-mannosidase activity. An important paralog of this gene is MAN2B2.

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.
