Phylogeny and Ontogeny of Chemical Signaling: Origin and Development of Hormone Receptors

摘要: Publisher Summary This chapter focuses on the origin and development of hormone receptors. Studies evolution show that there are no unique signal molecules, only those which selected to be hormones more suitable than others perform function. It is also probable receptors, structures able recognize environment. These develop into receptors following an encounter with a molecule for transmission. Hormonal imprinting occurs at first prospective receptor. results in specific numerous being produced by cell. The transmitted offspring generations. hormonal beginning evolutionary sequence retains its role higher organisms influences maturation around period birth. Imprinting necessary complete program receptor formation. not age-dependent but depends stage development; it can developed immature, differentiating cells adults. recognition system universal several ways expressed. In each method ligands.
