General Comments
ADGRF1 (formerly GPR110) is an orphan receptor that belongs to Family VI Adhesion-GPCRs together with ADGRF2-5 (formerly GPR111, GPR113, GPR115 and GPR116 respectively) [2]. The genes of Family VI Adhesion-GPCRs except ADGRF3 are syntenically clustered on human chromosome 6 and mouse chromosome 17 suggesting the evolution from an ancestral gene through gene duplication and exon shuffling [7]. The N terminus of ADGRF1 contains a GPCR proteolysis site (GPS) and a SEA (Sperm protein, Enterokinase and Agrin) domain. ADGRF1 is a receptor for N-docosahexaenoylethanolamine (synaptamide), an endogenous metabolite of docosahexaenoic acid, that potently promotes neurogenesis, neuritogenesis and synaptogenesis. ADGRF1 knockout mice show significant deficits in object recognition and spatial memory [5].
