For every TAFII dataset, there is a set of genes where the loss of expression upon TAFII inactivation parallels the loss of expression upon RNA polymerase II inactivation by the rpb1-1 temperature sensitive allele. This indicates that the TAFII inactivation must have been as rapid as polymerase inactivation by the rpb1-1 allele, which occurs within five minutes and describes a set of genes that are likely to be directly affected by loss of the TAFII in question. We have used this rpb1-1 criterion to evaluate the datasets for each of the TAFIIs examined here. The genes that fit this criterion are listed below.
