Tahikininski receptor 1 (TACR1, neurokininski 1 receptor, NK1R, ili receptor supstance P, SPR) je G protein spregnuti receptor koji je nađen u centralnom i perifernom nervnom sistemu. Endogeni ligand ovog receptora je supstanca P. On ima afinitet i za druge tahikinine. Protein je proizvod TACR1 gena.[1]
Osobine
Tahikinini su familija neuropeptida koji imaju zajednički hidrofobni C-terminalni region sa aminokiselinskom sekvencom Phe-X-Gly-Leu-Met-NH2, gde X predstavlja hidrofobni ostatak koji je bilo aromatičan ili beta-razgranati alifatik. N-terminalni region varira između različitih tahikinina.[2][3][4] Termin tahikinin odražava brzi početak delovanja ovih peptida u glatkim mišićima.[4] SP je najistraženiji i najpotentniji član tahikininske familije. On je undekapeptid sa aminokiselinskom sekvencom Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2.[2] SP se vezuje za sva tri tahikininska receptora, ali se najjače vezuje za NK1 receptor.[3]
Tahikininski NK1 receptor[5] sadrži 407 aminokiselina, i ima molekulsku težinu od 58 kDa.[2][6] NK1 receptor, kao i drugi tahikininski receptori, sadrži sedam hidrofobnih transmembranskih domena sa tri ekstracelularne i tri intracelularne petlje, ekstracelularnim amino-terminusom i citoplazmatičnim karboksilnim-terminusom. Petlje sadrže funkcionalna mesta, koja obuhvataju dve cisteinske aminokiseline koje formiraju disulfidni most, Asp-Arg-Tyr motiv koji je odgovoran za vezivanje arestina, i Lys/Arg-Lys/Arg-X-X-Lys/Arg sekvencu koja interaguje sa G-proteinima.[5][6]
Klinički značaj
Ovaj receptor se smatra atraktivnim ciljem za razvoj lekova sa analgetičkim i antidepresantskim svojstvima.[7][8] On je bio identifikovan kao kandidat u etiologiji manično-depresivne psihoze u jednoj studiji iz 2008.[9] Osim toga za TACR1 antagoniste je pokazano da potencijalno mogu da nađu primenu u lečenju alkoholizma.[10] Konačno, postoji mogućnost da se TACR1 antagonisti mogu koristiti kao antiemetike.[11]
