    Summary
    Enables SNAP receptor activity and anion binding activity. Involved in ascospore-type prospore assembly and vesicle fusion. Located in fungal-type vacuole membrane; plasma membrane; and prospore membrane. Part of SNARE complex. Human ortholog(s) of this gene implicated in several diseases, including Creutzfeldt-Jakob disease; Hirschsprung's disease; congenital diarrhea; familial hemophagocytic lymphohistiocytosis 4; and generalized epilepsy with febrile seizures plus 9. Orthologous to several human genes including STX1A (syntaxin 1A). [provided by Alliance of Genome Resources, Nov 2024]
