PTPRN - protein tyrosine phosphatase receptor type N Gene
Also Known as IA2; IA-2; ICA512; R-PTP-N; IA-2/PTP
Species: Homo sapiens
About PTPRN
This gene has 19 transcripts (splice variants), 258 orthologues and 35 paralogues. Biased expression in brain (RPKM 53.0), adrenal (RPKM 12.2) and 2 other tissues.
Summary
The protein encoded by this gene is a member of the protein tyrosine Phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region, a single transmembrane region, and a single catalytic domain, and thus represents a receptor-type PTP. This PTP was found to be an autoantigen that is reactive with insulin-dependent diabetes mellitus (IDDM) patient sera, and thus may be a potential target of autoimmunity in diabetes mellitus. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Dec 2010]
