Gen HTR2A koduje wielokrotnie przechodzące przez błonę komórkowąbiałko transbłonowe pełniące funkcję receptora dla serotoniny (5-hydroksytryptaminy) sprzężonego z białkiem G, którego pobudzenie podwyższa komórkowy poziom trifosforanu inozytolu (IP3) i diacyloglicerolu (DAG). Receptor 5-HT2A to podtyp receptora serotoninowego, który odgrywa kluczową rolę w ośrodkowym układzie nerwowym, szczególnie w obszarach związanych z poznawaniem, uczeniem się i pamięcią. Receptor 5-HT2A odpowiada też za modulowanie przekaźnictwa glutaminergicznego i aktywności NMDAR oraz wpływa na plastyczność synaptyczną.
