Alfa-2C adrenergički receptor (α_2C adrenoceptor, ADRA2C) je alfa-2 adrenergički receptor. On je kodiran humanim ADRA2C genom.

Receptor

Alfa-2-adrenergički receptori su 3 visoko homologna podtipa: alfa_2A, alfa_2B, i alfa_2C. Ti receptori imaju kritičnu ulogu u regulaciji otpuštanja neurotransmitera iz simpatičkih nerva i iz adrenergičkih neurona centralnog nervnog sistema. Ispitivanja na miševima su pokazala da su oba, alfa_2A i alfa_2C, podtipa neophodna za normalnu presinaptičku kontrolu otpuštanja transmitera iz simpatičkih nerva u srcu i iz centralnih noradrenergičkih neurona. Alfa_2A podtip inhibira otpuštanje transmitera na visokim stimulacionim frekvencijama, dok alfa_2C podtip modulira neurotransmisiju na niskim nivoima nervne aktivnosti.

Gen

Ovaj gen kodira alfa2C tip receptora. On ne sadrži introne.

Ligandi

Agonisti

• (R)-3-Nitrobifenilin (takođe slab antagonist α_2A i α_2B)

Antagonisti

• JP-1302: selektivan u odnosu na α2A, α2B, α2D
• spiroksatrin
• johimbin derivati 9 i 10: >43 puta selektivniji nego za α2A, α2B i α1 tipove
• N2-[4-(2,3-dihidro-benzo[1,4]dioksin-2-ilmetil)-[1,4]diazepan-1-il]-etil2-fenoksi-nikotinamid
