... presence of 20E,however, favors the formation of the AaEcR⁄ AaUSPheterodimer [13], indicating that the regulation of the activity of these proteins occurs through protein–pro-tein interactions, ... single protein. Interestingly, during the initialprocess of identifying the NR family members in the A. aegypti genome, we predicted two isoforms of AaFTZ-F1, differing only in their A ⁄ B region, ... Thisamino acid induced signal requires protein translation, as demonstrated by the lack of upregulation of AaHNF-4A in the presence of Chx (Fig. 4B). Address-ing the question of the nature of this...
