Antp Transcriptional Activity Is Modulated By The Formation Of The Trimeric Antp-Tbp Complexes With Tfiieβ, Exd And Bip2, Norma C. Hernández Bautista, Gustavo Jiménez Mejía, Claudia Altamirano Torres, Diana Reséndez Pérez

Research Symposium

Homeoproteins are transcriptional factors that bind to DNA through a highly conserved binding domain known as the homeodomain (HD) which recognizes short regions rich in AT to control the development of the body appendages of organisms. However, their structural and recognition similarities make it difficult to explain how homeoproteins are capable of carrying out their function. Previous results have shown that Antp homeoprotein can establish dimeric interactions with TBP, TFIIEβ, Exd, BIP2 and more recently through BiFC-FRET we confirmed that Antp and TBP can form trimeric complexes with TFIIEβ/Exd/BIP2. Therefore, is important to show how these trimeric complexes modulate Antp …
