Automated description from the Alliance of Genome Resources
Exhibits syntaxin-1 binding activity and syntaxin-3 binding activity. Involved in cellular response to interferon-gamma and exocytosis. Localizes to the apical plasma membrane; phagocytic vesicle; and zymogen granule membrane. Predicted to colocalize with the secretory granule. Human ortholog(s) of this gene implicated in familial hemophagocytic lymphohistiocytosis 5. Is expressed in several structures, including brain; gut; respiratory system; sensory organ; and urinary system. Orthologous to human STXBP2 (syntaxin binding protein 2).
