Neurokinin B

Description

Vertebrate tachykinins encoded by TAC3 gene (Tac2 in rodents). In 1983, Kangawa et al. isolated neurokinin B (NKB) from the porcine spinal cord and elucidated the primary sequence as Asp-Met-His-Asp-Phe-Phe-Val-Gly-Leu-Met-amide, followed by the characterization of other tetrapod NKB. In 2012, teleost NKB and its-gene-related peptide, NKF, were identified.

What are the applications of Application

Neurokinin B is a synthetic ligand for NK-1R3

Definition

ChEBI: Neurokinin B is a polypeptide. It is a mammalian neuropeptide of 10 amino acids that belongs to the tachykinin family is similar in structure and action to substance P and neurokinin A. It has the ability to excite neurons, dilate blood vessels, and contract smooth muscles, such as those in the urinary bladder and uterus.

Biochem/physiol Actions

Neurokinin B is a ten-residue peptide. It is an endogenous tachykinin agonist with preference for the NK-3 receptor. It is a potent bronchoconstrictor and may have a neuromodulatory role in the brain. Neurokinin B has a role in slow synaptic or non-synaptic communication.
