A new T-cell receptor gene located within the alpha locus and expressed early in T-cell differentiation.
A new T-cell receptor gene lies just 5' to the J alpha C alpha coding regions. Its placement in this location suggests a novel mechanism for the regulation of expression of one T-cell receptor polypeptide to another during ontogeny. Rearrangement of this locus occurs very early in thymic differentiation and its RNA expression parallels that of the gamma-chain in thymic subpopulations, making this a possible candidate for the recently described delta-chain of the T-cell receptor.
