Description

Predicted to enable beta-N-acetylhexosaminidase activity. Predicted to be involved in ganglioside catabolic process and glycosaminoglycan metabolic process. Predicted to act upstream of or within carbohydrate metabolic process. Predicted to be located in lysosome. Predicted to be active in membrane. Is expressed in several structures, including axis; lens placode; optic vesicle; polster; and visual system. Human ortholog(s) of this gene implicated in Tay-Sachs disease. Orthologous to human HEXA (hexosaminidase subunit alpha).
