Protein Coding Gene : Ptprn2 protein tyrosine phosphatase receptor type N polypeptide 2

Primary Identifier  MGI:107418 Organism  mouse, laboratory
Chromosome  12 NCBI Gene Number  19276
Mgi Type  protein coding gene
description  FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0)

Predicted to enable histone H2AXY142 phosphatase activity; non-membrane spanning protein tyrosine phosphatase activity; and protein tyrosine phosphatase activity, metal-dependent. Involved in insulin secretion involved in cellular response to glucose stimulus and neurotransmitter secretion. Located in 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).
PHENOTYPE: Homozygous null mice display impaired glucose tolerance but normal fasting and non-fasting blood glucose and insulin levels. [provided by MGI curators]
