Previous GeneCards Identifiers for PTPRN Gene
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]
GeneCards Summary for PTPRN Gene
PTPRN (Protein Tyrosine Phosphatase, Receptor Type N) is a Protein Coding gene. Diseases associated with PTPRN include Diabetes Mellitus, Insulin-Dependent and Microinvasive Cervical Squamous Cell Carcinoma. Among its related pathways are PAK Pathway and Allograft rejection. GO annotations related to this gene include phosphatase activity and spectrin binding. An important paralog of this gene is PTPRN2.
UniProtKB/Swiss-Prot for PTPRN Gene
Plays a role in vesicle-mediated secretory processes (PubMed:24843546). Required for normal accumulation of secretory vesicles in hippocampus, pituitary and pancreatic islets (By similarity). Required for the accumulation of normal levels of insulin-containing vesicles and preventing their degradation (PubMed:24843546). Plays a role in insulin secretion in response to glucose stimuli (PubMed:24843546). Required for normal accumulation of the neurotransmitters norepinephrine, dopamine and serotonin in the brain (By similarity). In females, but not in males, required for normal accumulation and secretion of pituitary hormones, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (By similarity). Seems to lack intrinsic enzyme activity (By similarity).
