5-HT5A (5-hidroksitriptaminski (serotoninski) receptor 5A, HTR5A) je protein koji je kod ljudi kodiran HTR5A genom.[1][2]
Protein kodiran 5-HT5A genom je član familije 5-hidroksitriptaminskih receptora. Njegov endogeni ligand je 5-hidroksitriptamin. On snižava cAMP nivoe putem Gi i Go proteina.[3] Za ovaj protein je pokazano da delom funkcioniše putem regulacije intracelularne mobilizacije Ca2+.[1]
Glodari imaju dva funkcionalna tipa 5-HT5 receptora, 5-HT5A i 5-HT5B,[4] Ljudi takože imaju 5-HT5B gen, ali njegova kodirajuća sekvenca sadrži stop kodone, tako da taj gen nije funkcionalan, i samo je 5-HT5A izražen u ljudskom mozgu.[5]
Neurotransmiter serotonin (5-hidroksitriptamin, 5-HT) uzima učešće u velikom broju psihijatrijskih stanja, kao i u vazokonstriktivnim i vazodilatornim efektima.[1]
Mali broj visoko selektivnih liganda je komercijalno dostupan za 5-HT5A receptor. Selektivna aktivacija ovog receptora se može ostvariti korištenjem neselektivnog agonista serotoninskog receptor 5-karboksamidotriptamina u kombinaciji sa selektivnim antagonistima za druge ciljeve (primarno 5-HT1A, 5-HT1B, 5-HT1D i 5-HT7).[6][7]
- Valerenska kiselina, komponenta valerijana, deluje kao 5HT5A parcijalni agonist.[8]
- DE19900637A1, selektivni ligand, Ki = 124 nM.[9]
- Latrepirdin (nije selektivan)[10]
