UAF, together with the TATA-binding transcription initiation factor protein TBP, then recruits an essential core factor to the promoter, to form a stable preinitiation complex [1]. This Rrn9 domain, which seems to be constrained to fungi, is the two highly conserved regions of proteins which form one of the subunits of UAF and appears to be the region responsible for the interaction with TBP. The family includes the S.pombe Arc1 protein, Swiss:Q10204, which is found to be essential for the accumulation of condensin at kinetochores [2].

This domain is found at the C terminal of DEK and is of clinical importance since it can reverse the characteristic abnormal DNA-mutagen sensitivity in fibroblasts from ataxia-telangiectasia (A-T) patients [3]. The structure of this domain shows it to be homologous to the E2F/DP transcription factor family [1]. This domain is also found in chitin synthase proteins like Swiss:Q8TF96, and in protein phosphastases such as Swiss:Q6NN85.
