We demonstrate in male and female rats that GABAB receptors receptors alter Pr, whereas 5-HT1B receptors modulation by Gβγ, but one - a GABAB receptor inhibits Ca2+ entry while another - a 5-HT1B receptor GABAB receptors alter Pr leaving synaptic properties unchanged, while 5-HT1B receptors fundamentally Co-activation of these receptors allows synaptic integration because of convergence of GABAB receptor

The sixth transmembrane region of a pheromone G-protein coupled receptor, Map3, is implicated in discrimination the molecular recognition of two peptidyl mating pheromones by their corresponding G-protein coupled receptors Although such pheromone/receptor systems are likely to function in both mate choice and prezygotic isolation , very few studies have focused on the stringency of pheromone receptors. GPCRs might reflect the significantly distinct stringency/flexibility of their respective pheromone/receptor
