Hemokinin 1 (HK1) is an endogenous agonist for all tachykinin receptors. However, it is highly selective for the NK1 (neurokinin 1) receptor. HK1 and substance-P compete with each other for binding to NK1. HK1 is involved in the B-cell as well as T-cell development.
NK1 tachykinin receptor agonist.
