Protocol
Specificity / Sensitivity
TCPTP (TC45) (D7T7D) Rabbit mAb recognizes endogenous levels of total TCPTP (TC45) protein. This antibody does not recognize the 48 kDa (TC48) isoform.
Species Reactivity:
Human, Mouse, Rat, Hamster, Monkey
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Bovine, Dog, Pig
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro382 of human TCPTP (TC45) protein.
Background
T cell protein tyrosine phosphatase (TCPTP, PTPN2, PTN2) is a non-receptor protein tyrosine phosphatase (PTP) that regulates signal transduction pathways by catalyzing the dephosphorylation of tyrosine residues (1). Two described TCPTP splice variants include a 48 kDa isoform (TC48) that is targeted to secretory pathway organelles (e.g., endoplasmic reticulum) by a hydrophobic carboxy terminus, and a 45 kDa isoform (TC45) that actively shuttles between the nucleus and cytoplasm (2). TCPTP substrates include receptor and non-receptor tyrosine kinases, such as EGFR, JAK1/3, and Src-family kinases, as well as STAT3 and other nuclear substrates (3-6). Research studies show that the corresponding PTPN2 gene is deleted in a subset of human T-cell acute lymphoblastic leukemias. The loss of TCPTP has been suggested to promote tumor progression through enhanced JAK/STAT signaling (7,8).
