生物活性
Neurokinin A (Substance K) 是速激肽家族的一種肽類神經(jīng)遞質(zhì)，通過 NK-2 受體發(fā)揮作用。在人氣道和胃腸道組織中作為主要的介體。靶點
NK-2 receptor
體外研究
Neurokinin A (substance K) is a peptide neurotransmitter of the tachykinin family with potential as a major mediator in human airway and gastrointestinal tissues. Neurokinin A acts via the NK-2 receptor believed to be localized on smooth muscle cells and pharmacologically coupled to a GTP-binding protein. Neurokinin A is a member of a family of peptide neurotransmitters known as tachykinins. These peptides are associated with the central and peripheral nervous systems and display a wide tissue distribution. Tachykinins share the COOH-terminal structure Phe-X-Gly-Leu-Met-NH. The best known members of this family are Substance P and Neurokinin A or Substance K.
