Gene: GBA2

Alternate names for this Gene: AD035|NLGase|SPG46

Gene Summary: This gene encodes a microsomal beta-glucosidase that catalyzes the hydrolysis of bile acid 3-O-glucosides as endogenous compounds. Studies to determine subcellular localization of this protein in the liver indicated that the enzyme was mainly enriched in the microsomal fraction where it appeared to be confined to the endoplasmic reticulum. This putative transmembrane protein is thought to play a role in carbohydrate transport and metabolism.

Gene is located in Chromosome: 9

Location in Chromosome : 9p13.3

Description of this Gene: glucosylceramidase beta 2

Type of Gene: protein-coding
