Enables SNARE binding activity. Involved in positive regulation of neuron projection development. Predicted to be located in lysosome and melanosome. Predicted to be active in cytoplasmic vesicle; neuron projection; and plasma membrane. Human ortholog(s) of this gene implicated in eosinophilic esophagitis. Orthologous to human ANKRD27 (ankyrin repeat domain 27). [provided by Alliance of Genome Resources, Apr 2022]
