Abstract
The universal TATA-binding protein, TBP, is an essential component of the multiprotein complex known as transcription factor IID (TFIID). This complex, which consists of TBP and TBP-associated factors (TAFs), is essential for RNA polymerase II-mediated transcription. The molecular size of human TBP (37.7 kD) is close to the passive diffusion limit along the transport channel of the nuclear pore complex (NPC). Therefore, the possibility exists that NPCs restrict TBP translocation to the nuclear interior. Here we show for the first time, with patch-clamp and atomic force microscopy (AFM), that NPCs regulate TBP movement into the nucleus and that TBP (10−15–10−10 m) is capable of modifying NPC structure and function. The translocation of TBP was ATP-dependent and could be detected as a transient plugging of the NPC channels, with a concomitant transient reduction in single NPC channel conductance, γ, to a negligible value. NPC unplugging was accompanied by permanent channel opening at concentrations greater than 250 pm. AFM images demonstrated that the TBP molecules attached to and accumulated on the NPC cytosolic side. NPC channel activity could be recorded for more than 48 hr. These observations suggest that three novel functions of TBP are: to stabilize NPC, to force the NPC channels into an open state, and to increase the number of functional channels. Since TBP is a major component of transcription, our observations are relevant to the understanding of the gene expression mechanisms underlying normal and pathological cell structure and function.
