Predicted to enable SNAP receptor activity and syntaxin binding activity. Predicted to be involved in several processes, including Golgi ribbon formation; retrograde transport, endosome to Golgi; and vesicle docking. Predicted to act upstream of or within protein transport. Located in Golgi apparatus. Is expressed in several structures, including central nervous system; connective tissue; genitourinary system; gut; and immune system. Human ortholog(s) of this gene implicated in pseudohypoparathyroidism type IB. Orthologous to human STX16 (syntaxin 16). [provided by Alliance of Genome Resources, Apr 2022]
