The chicken gonadotropin-releasing hormone receptor (cGnRH-R) is notable for having a cytoplasmic carboxyl-terminal tail, which is not present in the mammalian GnRH-Rs. We have previously shown that the cGnRH-R undergoes rapid agonist-induced internalization, and requires the carboxyl-terminal tail for this process. To investigate the role of the carboxyl-terminal tail of the cGnRH-R in relation to its rapid internalization, and to identify the key residues involved, a series ...
