The T-cell receptor (TCR) genes (alpha, beta, delta, and gamma) are comprised of numerous, discontinuous coding segments that somatically rearrange to produce heterodimeric cell surface T-cell receptors, either alpha/beta (90%-95% of T cells) or gamma/delta (5%-10% of T cells).
transcription-control region. the cis-acting DNA sequences regulating transcription of a specific gene. transcription factor (TF). a general term for any protein, other than RNA polymerase, required to initiate or regulate transcription in eukaryotic cells.eneral TFs are involved in the formation of the transcription-preinitiation complexes near the start site and are required for transcription of all genes; specific TFs stimulate (activators) or inhibit (suppressors) transcription of particular genes by binding to their regulatory sequences. nested set transcription.
