Predicted to enable transmembrane receptor protein tyrosine phosphatase activity. Involved in positive regulation of anterior/posterior axon guidance; positive regulation of neurotransmitter secretion; and ventral cord development. Located in dense core granule and synapse. Expressed in several structures, including buccal cavity; neurons; preanal ganglion; somatic nervous system; and
uv1. Used to study Parkinson's disease and diabetes mellitus. Human ortholog(s) of this gene implicated in prediabetes syndrome and type 1 diabetes mellitus. Is an ortholog of human PTPRN2 (protein tyrosine phosphatase receptor type N2).
