| ncRNA Symbol: | PTPRJ | | Full Name: | protein tyrosine phosphatase, receptor type J | | Category: | mRNA | | Synonyms: | CD148|DEP1|HPTPeta|R-PTP-ETA|SCC1 | | Chromosome: | chr11 | | Strand: | + | | Coordinate: | | Start Site(bp): | 47980558 | End Site(bp): | 48170841 | | | Gene 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 containing five fibronectin type III repeats, a single transmembrane region, and a single intracytoplasmic catalytic domain, and thus represents a receptor-type PTP. This protein is present in all hematopoietic lineages, and was shown to negatively regulate T cell receptor signaling possibly through interfering with the phosphorylation of Phospholipase C Gamma 1 and Linker for Activation of T Cells. This protein can also dephosphorylate the PDGF beta receptor, and may be involved in UV-induced signal transduction. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008] | | External Links: | |
