About This Section

Entrez Gene summary for MAN1B1:
This gene encodes an enzyme belonging to the glycosyl hydrolase 47 family. This enzyme functions in N-glycan
biosynthesis, and is a class I alpha-1,2-mannosidase that specifically converts Man9GlcNAc to Man8GlcNAc isomer B. It
is required for N-glycan trimming to Man5-6GlcNAc2 in the endoplasmic-reticulum-associated degradation pathway.
Mutations in this gene cause autosomal-recessive intellectual disability. Alternative splicing results in multiple
transcript variants. A related pseudogene has been identified on chromosome 11. (provided by RefSeq, Dec 2011)

UniProtKB/Swiss-Prot: MA1B1_HUMAN, Q9UKM7
Function: Involved in glycoprotein quality control targeting of misfolded glycoproteins for degradation. It primarily
trims a single alpha-1,2-linked mannose residue from Man(9)GlcNAc(2) to produce Man(8)GlcNAc(2), but at high enzyme
concentrations, as found in the ER quality control compartment (ERQC), it further trims the carbohydrates to
Man(5-6)GlcNAc(2)

summary for MAN1B1:
Mannosidases are divided into two subtypes; I and II, (EC numbers 3.2.1.113 and 3.2.1.114 respectively)
which display a wide expression pattern. Mannosidase I hydrolyzes (1,2)-linked alpha-D-mannose residues in
the oligo-mannose oligosaccharide Man9(GlcNAc)2 and mannosidase II hydrolyzes (1,3)- and (1,6)-linked
alpha-D-mannose residues in Man5(GlcNAc)3. Both subtypes require a divalent cation cofactor. Mutations in
mannosidases can cause mannosidosis (mannosidase I deficiency).
