At very early stages in the intrathymic differentiation of T lymphocytes which will bear αβ T Cell Receptors (TCR), the TCR β chain forms a heterodimer with the pre-TCR α chain (pTα) to form the pre-TCR. This pre-TCR associates with the signal-transducing CD3 complex and controls the survival and proliferation of CD4- CD8- (DN) thymocytes, plays a role in allelic exclusion of the TCR β chain, directly or indirectly regulates TCR δ chain expression, and is eventually replaced by the TCR α chain as thymocytes mature. The 2F5 antibody reacts with the PTα on the surface of CD44- CD25-/lo DN thymocytes.
