Belongs to the TFIID complex which is composed of TATA binding protein (Tbp) and a number of TBP-associated factors (Tafs). Associates with TFIID-IIA (DA complex) to form TFIID-IIA-IIB (DAB-complex) which is then recognized by polymerase II.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Kr monomer (the activator) interacts with TfIIB, Kr dimers do not (FBrf0082559). Kr dimers engage in protein-protein interaction with TfIIEβ (FBrf0082559). Kr monomer-dimer transition alters Krs ability to interact with the general transcription machinery (FBrf0082559).
Isolated from a cDNA library using the human TFIIB gene as a probe.
