    Summary
    Enables beta-N-acetylglucosaminidase activity. Involved in sexual reproduction. Located in plasma membrane. Is expressed in several structures, including adult head; adult heart; embryonic/larval garland cell; larval circulatory system; and larval muscle system. Human ortholog(s) of this gene implicated in Sandhoff disease; Tay-Sachs disease; and spinal muscular atrophy. Orthologous to human HEXA (hexosaminidase subunit alpha) and HEXB (hexosaminidase subunit beta). [provided by Alliance of Genome Resources, Dec 2024]
