Transactivation of the HIV - 1 LTR by T3R alpha and several receptor mutants revealed that the 50 - amino - acid N - terminal A / B region of T3R alpha , known to interact with the basal transcription factor TFIIB , is critical for activation of both Tat - dependent and Tat - independent responsive sequences of the LTR .
