特异性
This PTPRN antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 288-316 amino acids from the Central region of human PTPRN.
背景介绍
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.
组织表达
Expression is restricted to neuroendocrine cells. Found in pancreas, brain and pituitary.

Colocalizes with insulin- containing secretory granules (PubMed:25561468). Primarily detected on secretory vesicle membranes. Transiently found at the cell membrane, when secretory vesicles fuse with the cell membrane to release their cargo. Is then endocytosed and recycled to secretory vesicles via the Golgi apparatus membranes. {ECO:0000250|UniProtKB:Q63259, ECO:0000269|PubMed:25561468} [ICA512-cleaved cytosolic fragment]: Nucleus
