Receptor for the hormone galanin and GALP. Receptor for the hormone spexin-1 (PubMed:24517231). The activity of this receptor is mediated by G proteins that activate the phospholipase C/protein kinase C pathway (via G(q)) and that inhibit adenylyl cyclase (via G(i)). {ECO:0000269|PubMed:24517231, ECO:0000269|PubMed:25691535, ECO:0000269|PubMed:9480833, ECO:0000269|PubMed:9685625, ECO:0000269|PubMed:9832121, ECO:0000269|PubMed:9880084}. This is the function of GALR2 (galanin receptor 2, Ensembl gene identifier ENSG00000182687).
