Anti-Peptide SIY T cell receptor (m67), pCDTCR1 (TCR-YC0962)


All products and services are For Research Use Only and CANNOT be used in the treatment or diagnosis of disease.

The 2C TCR represents an excellent model system for examining TCR cross-reactivity because it recognizes two well-characterized and distinct pMHC ligands as strong agonists. The 2C clone was originally isolated as an alloreactive T cell that recognizes Ld as a foreign MHC (23). 2C binds to and is activated by octamer and nonomer peptide fragments of the enzyme α-ketoglutarate dehydrogenase, called p2Ca and QL9, respectively, when bound to Ld (24, 25). Additionally, 2C is positively selected on Kb, and a synthetic peptide called SIY acts as a strong agonist when bound to Kb (26). The Ld-binding peptide QL9 (QLSPFPFDL) and the Kb-binding peptide SIY (SIYRYYGL) share no sequence identity other than a C-terminal leucine, and although Ld and Kb are both murine class I MHC molecules, they differ by 31 residues in the α1α2 domains, making these two ligands for the 2C TCR quite diverse. T cell lines were generated previously by transfection of the 58−/-T cell hybridoma with the 2C TCR or high-affinity mutant m6, m13, or m67 TCR.

Target

  • Introduction
  • The ability of a single TCR to cross-react with different pMHC (sometimes called TCR degeneracy) is a common feature of T cell biology and is thought to be functionally important in mounting a rapid and effective response to diverse foreign Ags. TCR cross-reactivity is also important in T cell selection processes, as a TCR must interact with a self-peptide to survive and be exported to the periphery. Finally, TCR cross-reactivity is important in the process that leads to transplant rejection through the recognition of a foreign MHC known as the alloantigen.
