Summaries for PTPN18 Gene

Entrez Gene Summary for PTPN18 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, the mitotic cycle, and oncogenic transformation. This PTP contains a PEST motif, which often serves as a protein-protein interaction domain, and may be related to protein intracellular half-live. This protein can differentially dephosphorylate autophosphorylated tyrosine kinases that are overexpressed in tumor tissues, and it appears to regulate HER2, a member of the epidermal growth factor receptor family of receptor tyrosine kinases. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2008]

GeneCards Summary for PTPN18 Gene

PTPN18 (Protein Tyrosine Phosphatase, Non-Receptor Type 18) is a Protein Coding gene. Among its related pathways are PAK Pathway and B Cell Receptor Signaling Pathway (WikiPathways). GO annotations related to this gene include phosphatase activity and non-membrane spanning protein tyrosine phosphatase activity. An important paralog of this gene is PTPN22.
