Prodos is a conserved transcriptional regulator that interacts with dTAF(II)16 in Drosophila melanogaster.

ABSTRACT: The transcription factor TFIID is a multiprotein complex that includes the TATA box binding protein (TBP) and a number of associated factors, TAF(II). Prodos (PDS) is a conserved protein that exhibits a histone fold domain (HFD). In yeast two-hybrid tests using PDS as bait, we cloned the Drosophila TAF(II), dTAF(II)16, as a specific PDS target. dTAF(II)16 is closely related to human TAF(II)30 and to another recently discovered Drosophila TAF, dTAF(II)24. PDS and dTAF(II)24 do not interact, however, thus establishing a functional difference between these dTAFs. The PDS-dTAF(II)16 interaction is mediated by the HFD motif in PDS and the N terminus in dTAF(II)16, as indicated by yeast two-hybrid assays with protein fragments. Luciferase-reported transcription tests in transfected cells show th
