General Comments
ADGRF4 (formerly GPR115) is an orphan receptor that belongs to Family VI Adhesion-GPCRs together with ADGRF1-3, 5 and 6 [1]. 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 [5].

Full coding sequence human cDNA is publicly available, IMAGE:8317335 [4] in mammalian expression vector pCDNA3.1.

Original gene prediction, AY140957 [2] incorrectly predicts the first two and last exons and includes two exons derived from the ADGRF2 gene. The predicted protein (Swiss-Prot ID: Q8IZF3) is longer than that predicted from the observed cDNAs. ADGRF2 is immediately upstream of the ADGRF4 gene.
