Adenozinski A3 receptor (ADORA3) je adenozinski receptor. On je kodiran humanim ADORA3 genom.

Funkcija

[uredi | uredi kod]

Adenozinski A3 receptori je G protein-spregnuti receptor koji učestvuje u mnogobrojnim ćelijskim signalnim putevima i fiziološkim funkcijama. On posreduje kontinuirane kardioprotektivne funkcije tokom srčane ishemije, i učestvuje u inhibiciji neutrofilne degranulacije kod neutrofilima-posredovane povrede tkiva. Smatra se da ima neurozaštitno ali i neurodegenerativno dejstvo.

Višestruke transkriptne varijante koje kodiraju različite izoforme su poznate za ovaj gen.[1]

Terapeutske implikacije
