Record overview

MGPD ID	MGP001221
Gene ID	2720
Species	Homo sapiens (Human)
Gene Name	galactosidase, beta 1
Gene Symbol	GLB1
Synonyms	EBP; ELNR1; MPS4B;
Alternate names	beta-galactosidase; acid beta-galactosidase; elastin receptor 1, 67kDa; lactase;
Chromosome	3
Map Location	3p21.33
EC Number	3.2.1.23
Summary	This gene encodes beta-galactosidase-1, a lysosomal enzyme that hydrolyzes the terminal beta-galactose from ganglioside substrates and other glycoconjugates. Defects in this gene are the cause of GM1-gangliosidosis and Morquio B syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]
