Galaninski receptor je G protein-spregnuti receptor, ili metabotropni receptor koji vezuje galanin.[1]

Galaninski receptori se mogu naći u perifernom i centralnom nervnom sistemu kao i u endokrinom sistemu. Do sada je poznato da postoje tri tipa: GAL-R1, GAL-R2, i GAL-R3.[2] Specifična funkcija svih podtipova nije potpuno istražena. Nedavno je došlo do napretka u pravljenju podtip-specifičnih nokaut miševa,[3][4] i prvih selektivnih liganda galaninskih receptorskih podtipova. Selektivni galaninski agonisti su antiepileptici,[5][6][7] dok su antagonisti antidepresanti i anksiolitici u životinjskim studijama,[8][9][10][11][12], tako da bilo agonisti ili antagonisti galaninskog receptora mogu potencijalno biti lekovi.
