This gene encodes a lysosomal membrane protein that cleaves the beta-glucosidic linkage of glycosylceramide, an intermediate in glycolipid metabolism. Mutations in this gene cause Gaucher disease, a lysosomal storage disease characterized by an accumulation of glucocerebrosides. A related pseudogene is approximately 12 kb downstream of this gene on chromosome 1.

Interacts with saposin-C (PubMed:10781797). Interacts with SCARB2 (PubMed:18022370). Interacts with TCP1 (PubMed:21098288). May interact with SNCA; may inhibit the glucosylceramidase activity (PubMed:23266198). Interacts with GRN; this interaction prevents aggregation of GBA-SCARB2 complex via interaction with HSPA1A upon stress (PubMed:27789271).
