T cell receptor Vβ12 (TCR Vβ12) is a variant of TCR β chain and, along with TCR α chain, forms the TCR heterodimer. In association with the CD3 complex, TCR α/β is responsible for antigen recognition through interaction with MHC-peptide complex to initiate the T cell-mediated immune responses. The MR11-1 antibody reacts with the Vβ12 TCR of mice bearing the b haplotype. It has been reported that Mtv-8 and Mtv-9 cause clonally deletion of Vβ12+ T cells.
