EGF-like module-containing mucin-like hormone receptor-like 2 also known as CD312 (cluster of differentiation 312) is a protein encoded by the ADGRE2 gene.^[3] EMR2 is a member of the adhesion GPCR family.^[4]^[5] Adhesion GPCRs are characterized by an extended extracellular region often possessing N-terminal protein modules that is linked to a TM7 region via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.^[6]

EMR2 is expressed by monocytes/macrophages, dendritic cells and all types of granulocytes.^[7] In the case of EMR2 the N-terminal domains consist of alternatively spliced epidermal growth factor-like (EGF-like) domains. EMR2 is closely related to CD97 with 97% amino-acid identity in the EGF-like domains. The N-terminal fragment (NTF) of EMR2 presents 2-5 EGF-like domains in human.^[8] Mice lack the Emr2 gene.^[9] This gene is closely linked to the gene encoding EGF-like molecule containing mucin-like hormone receptor 3 EMR3 on chromosome 19.
