General Comments
ADGRE3 (adhesion G protein-coupled receptor E3, formerly known as EMR3: EGF-like module containing, mucin-like, hormone receptor-like 3) is an orphan receptor that belongs to Family II Adhesion-GPCRs together with ADGRE5 and ADGRE1, ADGRE2 and ADGRE4 [1,3]. The genes of Family II Adhesion-GPCRs are syntenically clustered on human chromosome 19 suggesting the evolution from an ancestral gene through gene duplication and exon shuffling [4]. No mouse or rat ADGRE3 orthologues exist.

Full coding sequence human cDNA is publicly available, IMAGE:7211798 [5] in mammalian expression vector pCDNA3.1. Clone matches RefSeq and human reference genomic sequence.
