Gene Gene information from NCBI Gene database.
Entrez ID 2720
Gene name Galactosidase beta 1
Gene symbol GLB1
Synonyms (NCBI Gene)
EBPELNR1MPS4B
Chromosome 3
Chromosome location 3p22.3
Summary This gene encodes a member of the glycosyl hydrolase 35 family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature lysosomal enzy
