GENE INFORMATION
Gene name	PTPRN2 (HGNC Symbol)
Synonyms	IA-2beta, ICAAR, KIAA0387, phogrin
Description	Protein tyrosine phosphatase, receptor type, N polypeptide 2 (HGNC Symbol)
Entrez gene summary	This gene encodes a protein with sequence similarity to receptor-like protein tyrosine phosphatases. However, tyrosine phosphatase activity has not been experimentally validated for this protein. Studies of the rat ortholog suggest that the encoded protein may instead function as a phosphatidylinositol phosphatase with the ability to dephosphorylate phosphatidylinositol 3-phosphate and phosphatidylinositol 4,5-diphosphate, and this function may be involved in the regulation of insulin secretion. This protein has been identified as an autoantigen in insulin-dependent diabetes mellitus. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2015]
