Automated description from the Alliance of Genome Resources (Release 3.2)
Predicted to have protein tyrosine phosphatase activity. Involved in insulin secretion involved in cellular response to glucose stimulus and neurotransmitter secretion. Localizes to secretory granule membrane and synaptic vesicle membrane. Is expressed in several structures, including foregut-midgut junction; midgut endoderm; and nervous system. Used to study type 1 diabetes mellitus. Human ortholog(s) of this gene implicated in prediabetes syndrome and type 1 diabetes mellitus. Orthologous to human PTPRN2 (protein tyrosine phosphatase receptor type N2).
