Predicted to enable SNAP receptor activity; chloride channel inhibitor activity; and syntaxin binding activity. Predicted to be involved in several processes, including endosome to lysosome transport; positive regulation of T cell mediated cytotoxicity; and positive regulation of receptor localization to synapse. Located in endosome and perinuclear region of cytoplasm. Is expressed in central nervous system; ganglia; and neural retina. Orthologous to human STX7 (syntaxin 7).
