Research Symposium
Background: Hox proteins are transcriptional factors (TFs) that define segment identity during embryonic development regulating specific target genes. These TFs interact with cofactors for DNA specificity and other TFs to regulate gene expression, which include basal transcriptional machinery members like BIP2, Med19, TFIIEβ, M1BP and TBP. Since TBP glutamine homopeptide (PolyQ) act as an interaction domain involved transcriptional regulation, we analyzed if TBP interact with Antp, Scr, Ubx and AbdB through its PolyQ region.
Methods: We used Bimolecular Fluorescent Complementation (BiFC) to determine TBP interaction with Antp, Scr, Ubx and AbdB as well as the implication of their homeodomain (HD) …
