Cytosolic beta ‑Glucosidase/GBA3 in HeLa Human Cell Line. Cytosolic beta ‑Glucosidase/GBA3 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human Cytosolic beta ‑Glucosidase/GBA3 Monoclonal Antibody (Catalog # MAB59691) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Cytosolic beta-Glucosidase/GBA3
are three beta-glucosidases (GBA) in human genome. GBA1 endodes a
lysosomal membrane protein that cleaves the beta-glucosidic linkage of
glucosylceramide (1). GBA2 encodes a microsomal beta-glucosidase that
catalyzes the hydrolysis of bile acid 3-O-glucosides (2). GBA3 is a
cytosolic beta-glucosidase and is predominantly expressed in liver. GBA3
efficiently hydrolyzes beta-D-glucoside and beta-D-galactoside, but not
any known physiological beta-glycoside, suggesting that it may be
involved in detoxification of plant glycosides (3). GBA3 also has
significant neutral glycosylceramidase activity, suggesting that it may
be involved in a nonlysosomal catabolic pathway of glucosylceramide
metabolism (4). At the protein level, GBA3 shows significant homology
(>40%) with Klotho protein that is known for its association with
aging process (3, 4).
