The promoter regions of the T-cell receptor V9 y (TRGV9) and V2 5 (TRDV2) genes display short direct repeats but no TATA box236 bp upstream of the ATG codon [6]. The corresponding subclones were isolated respectively from XFI and XF6 (Vl), XSH4 (VZ), XSl and XSH4 (V3), XS13...
Of interest is the presence of a characteristic decanucleotide AGGTGGT(T)GAG in the promoter regions of both the TRDV2 and TRGV9 genes. Promoter region; Receptor, γ T-cell; Receptor, δ T-cell; Gene, variable; Transcription; (Human)...
