Protein Coding Gene : Glb1 galactosidase, beta 1

Primary Identifier  MGI:88151 Organism  mouse, laboratory
Chromosome  9 NCBI Gene Number  12091
Mgi Type  protein coding gene
description  FUNCTION: Automated description from the Alliance of Genome Resources (Release 7.1.0)

Enables beta-galactosidase activity. Predicted to be involved in galactose catabolic process. Located in extracellular space and lysosome. Is expressed in several structures, including alimentary system; cranium; genitourinary system; nervous system; and respiratory system. Used to study GM1 gangliosidosis. Human ortholog(s) of this gene implicated in GM1 gangliosidosis (multiple) and mucopolysaccharidosis IV (multiple). Orthologous to human GLB1 (galactosidase beta 1).
PHENOTYPE: Homozygotes for a targeted null mutation exhibit progressive spastic diplegia, emaciation, and accumulation of ganglioside GM1 and asialo GM1 in brain tissue. Mutants die at 7-10 months of age. [provided by MGI curators]
