Figure 5From: Differentiated adaptive evolution, episodic relaxation of selective constraints, and pseudogenization of umami and sweet taste genes TAS1Rs in catarrhine primatesHomology models of TAS1R1 and TAS1R2 VFTM domain. (A) The model of TAS1R1 VFTM domain, and positive selection sites locating at binding regions are marked. (B) The model of TAS1R2 VFTM domain, and positive selection sites locating at binding regions are marked.Back to article page
