Summaries for GBA3 Gene

Entrez Gene Summary for GBA3 Gene

  • The protein encoded by this gene is an enzyme that can hydrolyze several types of glycosides. This gene is a polymorphic pseudogene, with the most common allele being the functional allele that encodes the full-length protein. Some individuals, as represented by the reference genome allele, contain a single nucleotide polymorphism that results in a premature stop codon in the coding region, and therefore this allele is pseudogenic due to the failure to produce a functional full-length protein. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Mar 2013]

GeneCards Summary for GBA3 Gene

GBA3 (Glucosylceramidase Beta 3 (Gene/Pseudogene)) is a Protein Coding gene. Diseases associated with GBA3 include gaucher's disease. Among its related pathways are Metabolism and Sphingolipid metabolism. GO annotations related to this gene include hydrolase activity, hydrolyzing O-glycosyl compounds and beta-glucosidase activity. An important paralog of this gene is KL.

UniProtKB/Swiss-Prot for GBA3 Gene

  • Glycosidase probably involved in the intestinal absorption and metabolism of dietary flavonoid glycosides. Able to hydrolyze a broad variety of glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens. Possesses beta-glycosylceramidase activity and may be involved in a nonlysosomal catabolic pathway of glycosylceramide.

Tocris Summary for GBA3 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.
