Tachykinin receptors

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

« Hide More detailed introduction

Tachykinin receptors (provisional nomenclature, [18]) are activated by the endogenous peptides SP (TAC1, P20366) (SP), NKA (TAC1, P20366) (NKA; previously known as substance K, neurokinin α, neuromedin L), neurokinin B (TAC3, Q9UHF0) (NKB; previously known as neurokinin β, neuromedin K), NP-K (TAC1, P20366) and neuropeptide γ (TAC1, P20366) (N-terminally extended forms of neurokinin A). The neurokinins (A and B) are mammalian members of the tachykinin family, which includes peptides of mammalian and nonmammalian origin containing the consensus sequence: Phe-x-Gly-Leu-Met. Marked species differences in in vitro pharmacology exist for all three receptors, in the context of nonpeptide ligands.
