Chromosome | 9 | NCBI Gene Number | 15211 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables beta-N-acetylhexosaminidase activity. Involved in dermatan sulfate catabolic process and hyaluronan catabolic process. Acts upstream of or within several processes, including adult walking behavior; ganglioside catabolic process; and nervous system development. Located in membrane. Is active in lysosome. Is expressed in brain; mandible; and maxilla. Used to study Tay-Sachs disease. Human ortholog(s) of this gene implicated in Tay-Sachs disease. Orthologous to human HEXA (hexosaminidase subunit alpha). PHENOTYPE: Homozygous mutants accumulate excess amounts of GM2 ganglioside that is stored in neurons as membranous cytoplasmic bodies typically seen in the neurons of Tay-Sachs disease patients. However, the mutant mice appear to be functionally normal. [provided by MGI curators] |
