Human Gene PTPRD (uc003zkk.3) Description and Page Index
  Description: Homo sapiens protein tyrosine phosphatase, receptor type, D (PTPRD), transcript variant 1, mRNA.
RefSeq Summary (NM_002839): 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 contains an extracellular region, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus represents a receptor-type PTP. The extracellular region of this protein is composed of three Ig-like and eight fibronectin type III-like domains. Studies of the similar genes in chicken and fly suggest the role of this PTP is in promoting neurite growth, and regulating neurons axon guidance. Multiple alternatively spliced transcript variants of this gene have been reported. A related pseudogene has been identified on chromosome 5. [provided by RefSeq, Jan 2010].

DESCRIPTION: RecName: Full=Receptor-type tyrosine-protein phosphatase delta; Short=Protein-tyrosine phosphatase delta; Short=R-PTP-delta; EC=; Flags: Precursor;
CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.
SUBUNIT: Interacts with IL1RAPL1 (via extracellular region); interaction is required for IL1RAPL1-mediated synapse formation (By similarity). Interacts with PPFIA1, PPFIA2 and PPFIA3.
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
PTM: A cleavage occurs, separating the extracellular domain from the transmembrane segment. This process called 'ectodomain shedding' is thought to be involved in receptor desensitization, signal transduction and/or membrane localization.
SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Receptor class 2A subfamily.
SIMILARITY: Contains 8 fibronectin type-III domains.
SIMILARITY: Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
SIMILARITY: Contains 2 tyrosine-protein phosphatase domains.

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.
