Description

Predicted to have N-acetyl-beta-D-galactosaminidase activity and beta-N-acetylhexosaminidase activity. Predicted to be involved in carbohydrate metabolic process. Human ortholog(s) of this gene implicated in Tay-Sachs disease. Is expressed in several structures, including axis; lens placode; optic vesicle; polster; and visual system. Orthologous to human HEXA (hexosaminidase subunit alpha).
