TAND-1 and TAND-2 of TAF-1 blocks the DNA binding cleft of TPB and the n-terminal stirrup.
<h3>Explain function of TAF(I).</h3>
Part of a protein known as transcription factor IID can be made using instructions from the TAF1 gene (TFIID).
The body's cells and tissues all have this protein, which connects to and binds to DNA there.
The majority of genes' activity is controlled by transcription factor IID.
A preinitiation complex made up of a number of initiation components must be assembled before RNA polymerase II can begin transcription of a gene from its core promoter region.
It is believed that the TFIID transcription factor complex, which is made up of the TATA-binding protein (TBP) and TBP-associated factors (TAF(II)s), binds to the various promoters in a sequence-specific manner to initiate the assembly of this complex.
Here, we identify and characterize a novel multiprotein complex made up of a number of TAF(II)s and other proteins but lacking either TBP or a TBP-like factor.
In in vitro transcription experiments, this complex can take the place of TFIID on both TATA-containing and TATA-lacking promoters.
External stimulus. The rain is something out of your control while you're waiting. Rain is not something you are doing nor is it a response to you waiting for the bus.
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
