U neuronauci supstanca P (SP) je neuropeptid: undekapeptid koji funkcioniše kao neurotransmiter i neuromodulator.^[5]^[6] Ovaj molekul pripada familiji tahikininskih neuropeptida. Supstanca P i njen blisko srodni neuropeptid neurokinin A (NKA) nastaju iz poliproteinskog prekurzora nakon diferencijalnog splajsovanja gena preprotahikinina A. Aminokiselinska sekvenca supstance P je^[7]^[8]:

Arg Pro Lys Pro Gln Gln Phe Phe Gly Leu Met

Supstanca P se oslobađa iz završetaka specifičnih senzornih nerava. Nađena je u mozgu i kičmenoj moždini, i učestvuje u inflamatornim procesima i senzaciji bola.

Otkriće

Supstancu P su originalno otkrili 1931 Ulf von Euler i Džon H. Gadum kao extrakt tkiva koji izaziva intestinalne kontrakcije in vitro.^[9] Njena distribucija u tkivu i biološka dejstva su detaljno ispitivana tokom decenija koje su sledele.^[5] NKA (prethodno poznata kao supstanca K ili neuromedin L) je izolovana iz svinjske kičmene moždine 1983, i ustanovljeno je da takođe stimuliše intestinalne kontrakcije.^[10]

Receptor

Endogeni receptor supstance P je neurokininski 1 receptor (NK1-receptor, NK1R).^[11] On pripada familiji tahikininskih receptora G protein-spregnutih receptora.^[12]
