Funkcija

Protein kodiran genom je član familije 5-hidroksitriptaminskih receptora. Njegov endogeni ligand je 5-hidroksitriptamin. On snižava cAMP nivoe putem i proteina.^[3] Za ovaj protein je pokazano da delom funkcioniše putem regulacije intracelularne mobilizacije ²⁺.^[1]

Glodari imaju dva funkcionalna tipa 5-₅ receptora, i ,^[4] Ljudi takože imaju gen, ali njegova kodirajuća sekvenca sadrži stop kodone, tako da taj gen nije funkcionalan, i samo je izražen u ljudskom mozgu.^[5]

Klinički značaj

Neurotransmiter serotonin (5-hidroksitriptamin, 5-) uzima učešće u velikom broju psihijatrijskih stanja, kao i u vazokonstriktivnim i vazodilatornim efektima.^[1]

Selektivni Ligandi

Mali broj visoko selektivnih liganda je komercijalno dostupan za receptor. Selektivna aktivacija ovog receptora se može ostvariti korištenjem neselektivnog agonista serotoninskog receptor 5-karboksamidotriptamina u kombinaciji sa selektivnim antagonistima za druge ciljeve (primarno i ).^[6][7]

Agonisti

DE19900637A1

• Valerenska kiselina, komponenta valerijana, deluje kao parcijalni agonist.^[8]
• , selektivni ligand, = 124 .^[9]

Antagonisti

• Latrepirdin (nije selektivan)^[10]
