PTPN7 Peptide - Middle Region Blocking Peptide

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 gene is preferentially expressed in a variety of hematopoietic cells, and is an early response gene in lymphokine stimulated cells. The non-catalytic N-terminus of this PTP can interact with MAP kinases and suppress the MAP kinase activities. This PTP was shown to be involved in the regulation of T cell antigen receptor (TCR) signaling, which was thought to function through dephosphorylating the molecules related to MAP kinase pathway. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2010]

HePTP: a non-receptor protein-tyrosine phosphatase. Preferentially expressed in a variety of hematopoietic cells, and is an early response gene in lymphokine stimulated cells. Its noncatalytic N-terminus can interact with MAP kinases and suppress the MAP kinase activities. Shown to be involved in the regulation of T cell antigen receptor (TCR) signaling, which was thought to function through dephosphorylating the molecules related to MAP kinase pathway. Three alternatively spliced transcript variants of this gene, which encode two distinct isoforms, are reported. May play a role in the regulation of lymphocyte development.
