Example sentences for: tfiid
How can you use “tfiid” in a sentence? Here are some example sentences to help you improve your vocabulary:
The central component of PIC is the general transcription factor (GTF) TFIID, which contains the TATAbox- binding protein (TBP) and 12 to 15 TBP-associated factors (TAFs).
Taken altogether, the above results show that the intracellular level of TBP and TAF II 135 and consequently TFIID is significantly reduced in differentiated cells through T-RA-induced proteolytic degradation.
TFIID acts as a “landing pad” for other GTFs and RNAPII to nucleate PIC assembly.
RNA polymerase II (pol II) transcription factor TFIID comprises the TATA-binding protein (TBP) and a set of TBP-associated factors (TAF II s) [ [ 1 2 3 ] ]. At least 12 TAF II s have been identified in TFIID and cloning of their cDNAs has shown an evolutionary conservation of TAF II s from yeast to mammals [ [ 4 5 6 7 ] ]. TAF II s are not only components of the TFIID complex, but a subset of TAF II s are also found in the SAGA, PCAF, TFTC/STAGA complexes which lack TBP [ [ 8 9 10 11 12 ] ].
To determine whether components of basal transcription factor TFIID were subject to regulation during F9 cell differentiation, immunoblotting with monoclonal antibodies against TBP and a number of TAF II s, was used to monitor the levels of the respective proteins in differentiated cell extracts (see Materials and Methods).
