GBA (β-glucocerebrosidase) gene is mapped to human chromosome 1q21. It is a lysosomal enzyme and is widely expressed. The protein has domain I with three‐stranded anti‐parallel β‐sheets, domain II with two β‐sheets making an immunoglobulin‐like domain and domain III with eight‐stranded β/αtriosephosphate isomerase (TIM) barrel.
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. Alternative splicing results in multiple transcript variants encoding the same protein. (provided by RefSeq)
Immunogen
GBA (NP_000148, 146 a.a. ~ 235 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.
Monoclonal Anti-GBA antibody has been used in immunofluorescence staining.
Biochem/physiol Actions
GBA (β-glucocerebrosidase) is responsible for the conversion of the glycolipid glucocerebroside to ceramide and glucose. Mutations in this gene are associated with Gaucher disease and Parkinson disease.

Gaucher disease (GD) is an autosomal recessive lysosomal disorder due to beta-glucosidase gene (GBA) mutations. The molecular diagnosis of GD is complicated by the presence of recombinant alleles originating from a highly homologous pseudogene. Clinical exome sequencing (CES) is a

Gaucher disease (GD) is caused by bi-allelic mutations in GBA1, the gene that encodes acid β-glucocerebrosidase (GCase). Individuals affected by GD have hematologic, visceral and bone abnormalities, and in severe cases there is also neurodegeneration. To shed light on the
Patients with Gaucher Disease (GD) exhibit three phenotypes, including type 1 (non-neuronopathic), type 2 (acute neuronopathic), and type 3 (subacute neuronopathic). Identifying which GBA changes represent benign polymorphisms and which may result in disease-causing mutations is essential for diagnosis and
