== Function ==

This gene encodes a member of the latrophilin subfamily of G protein-coupled receptors (GPCR). Latrophilins may function in both cell adhesion and signal transduction. In experiments with non-human species, endogenous proteolytic cleavage within a cysteine-rich GPS (G-protein-coupled-receptor proteolysis site) domain resulted in two subunits (a large extracellular N-terminal cell adhesion subunit and a subunit with substantial similarity to the secretin/calcitonin family of GPCRs) being non-covalently bound at the cell membrane. Latrophilin-1 has been shown to recruit the neurotoxin from black widow spider venom, alpha-latrotoxin, to the synapse plasma membrane.<ref name="entrez" /> Latrophilin-1 is involved in glucose sensing in the brain and regulating glucose intake.<ref name="Chhabra_2023">{{cite journal | vauthors = Chhabra KH, Bathina S, Faniyan TS, Samuel DJ, Raza MU, de Souza Cordeiro LM, Viana Di Prisco G, Atwood BK, Robles J, Bainbridge L, Davis A | display-authors = 6 | title = ADGRL1 is a glucose receptor involved in mediating energy and glucose homeostasis | journal = Diabetologia | volume = 67| issue = 1| date = September 2023 | pages = 170–189 | pmid = 37712955 | doi = 10.1007/s00125-023-06010-6 | pmc = 10709246 | s2cid = 261886742 | doi-access = free }}</ref><ref>{{cite journal|vauthors= Stillwell JD, Elmi MA, Parag RR, Van Meir EG| title= Therapeutic targeting of adhesion GPCRs: a status update and future potential|year=2026|journal=Expert Opinion on Drug Discovery|volume=21|issue=5|page=447-463|doi=10.1080/17460441.2026.2662413|doi-access=free}}</ref>
