CC   -!- FUNCTION: G protein-coupled receptor for 5-hydroxytryptamine
CC       (serotonin) (PubMed:14744596, PubMed:1513320, PubMed:1608964,
CC       PubMed:1733778, PubMed:21422162, PubMed:33762731). Also functions as a
CC       receptor for various alkaloids and psychoactive substances
CC       (PubMed:14744596, PubMed:1513320, PubMed:1608964, PubMed:1733778,
CC       PubMed:21422162, PubMed:33762731). Ligand binding causes a conformation
CC       change that triggers signaling via guanine nucleotide-binding proteins
CC       (G proteins) and modulates the activity of downstream effectors, such
CC       as adenylate cyclase (PubMed:14744596, PubMed:1513320, PubMed:1608964,
CC       PubMed:1733778, PubMed:21422162, PubMed:33762731). HTR1E is coupled to
CC       G(i)/G(o) G alpha proteins and mediates inhibitory neurotransmission by
CC       inhibiting adenylate cyclase activity (PubMed:33762731,
