Emr4, or Adhesion G protein-coupled receptor E4, pseudogene, is a human gene encoded by ADGRE4P. It may also be known as: Putative adhesion G protein-coupled receptor E4P; EGF-like module receptor 4; EGF-like module-containing mucin-like hormone receptor-like 4; G-protein coupled receptor 127; G-protein coupled receptor PGR16; EMR4; EMR4P; FIRE; GPR127; PGR16; egf-like module containing, mucin-like, hormone receptor-like 4 pseudogene. The encoded protein has an amino acid length of 457 and a mass of 50.9 kDa. Emr4 is a member of the G-protein coupled receptor 2 family, Adhesion G-protein coupled receptor (ADGR) subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat.
