Human Gene PTPRE (ENST00000306042.9) Description and Page Index
  Description: Homo sapiens protein tyrosine phosphatase receptor type E (PTPRE), transcript variant 2, mRNA. (from RefSeq NM_130435)
RefSeq Summary (NM_130435): 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. Several alternatively spliced transcript variants of this gene have been reported, at least two of which encode a receptor-type PTP that possesses a short extracellular domain, a single transmembrane region, and two tandem intracytoplasmic catalytic domains; another one encodes a PTP that contains a distinct hydrophilic N-terminus, and thus represents a nonreceptor-type isoform of this PTP. Studies of the similar gene in mice suggested the regulatory roles of this PTP in RAS related signal transduction pathways, cytokine-induced SATA signaling, as well as the activation of voltage-gated K+ channels.

  ID: PTPRE_HUMAN
DESCRIPTION: RecName: Full=Receptor-type tyrosine-protein phosphatase epsilon; Short=Protein-tyrosine phosphatase epsilon; Short=R-PTP-epsilon; EC=3.1.3.48; Flags: Precursor;
FUNCTION: Isoform 1 plays a critical role in signaling transduction pathways and phosphoprotein network topology in red blood cells. May play a role in osteoclast formation and function (By similarity).
FUNCTION: Isoform 2 acts as a negative regulator of insulin receptor (IR) signaling in skeletal muscle. Regulates insulin- induced tyrosine phosphorylation of insulin receptor (IR) and insulin receptor substrate 1 (IRS-1), phosphorylation of protein kinase B and glycogen synthase kinase-3 and insulin induced stimulation of glucose uptake (By similarity).
FUNCTION: Isoform 1 and isoform 2 act as a negative regulator of FceRI-mediated signal transduction leading to cytokine production and degranulation, most likely by acting at the level of SYK to affect downstream events such as phosphorylation of SLP76 and LAT and mobilization of Ca(2+) (By similarity).
CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.
SUBUNIT: Monomer. Isoform 2: Homodimer. Can form oligomers. Dimerization is increased by oxidative stress and decreased by EGFR. Isoform 2 interacts with GRB2 (By similarity).
SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Single-pass type I membrane protein.
SUBCELLULAR LOCATION: Isoform 2: Cytoplasm. Note=Predominantly cytoplasmic. A small fraction is also associated with nucleus and membrane. Insulin induces translocation to the membrane (By similarity).
SUBCELLULAR LOCATION: Isoform 3: Cytoplasm.
TISSUE SPECIFICITY: Expressed in giant cell tumor (osteoclastoma rich in multinucleated osteoclastic cells).
INDUCTION: Up-regulated by 12-O-tetradecanoylphorbol-13-acetate (TPA) in HL-60 cells.
DOMAIN: The tyrosine-protein phosphatase 2 domain (D2) mediates dimerization. The extreme N- and C- termini of the D2 domain act to inhibit dimerization and removal of these sequences increases dimerization and inhibits enzyme activity (By similarity).
PTM: A catalytically active cytoplasmic form (p65) is produced by proteolytic cleavage of either isoform 1, isoform 2 or isoform 3.
PTM: Isoform 1 and isoform 2 are phosphorylated on tyrosine residues by tyrosine kinase Neu.
PTM: Isoform 1 is glycosylated.
SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Receptor class 4 subfamily.
SIMILARITY: Contains 2 tyrosine-protein phosphatase domains.
SEQUENCE CAUTION: Sequence=AAC50324.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Sequence of unknown origin in the C-terminal part;

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
