Lysosomal acid glucosylceramidase (GCase)

Target
GCase
Molecular classification
Enzyme, Glycoside hydrolase
01

Overview

Lysosomal acid glucosylceramidase (GCase), encoded by the GBA1 gene, is a lysosomal enzyme responsible for the hydrolysis of glucocerebroside into glucose and ceramide. It plays a crucial role in sphingolipid metabolism and cellular membrane turnover. Mutations in GBA1 lead to Gaucher disease, a lysosomal storage disorder. GBA1 variants are also associated with an increased risk of Parkinson's disease.
