EGF-like module-containing mucin-like hormone receptor-like 1 also known as F4/80 is a protein encoded by the ADGRE1 gene.^[5]^[6]^[7]^[8]^[9] EMR1 is a member of the adhesion GPCR family.^[10]^[11] 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.^[12]

EMR1 expression in human is restricted to eosinophils and is a specific marker for these cells.^[13] The murine homolog of EMR1, F4/80, is a well-known and widely used marker of murine macrophage populations.^[14] The N-terminal fragment (NTF) of EMR1 contains 4-6 Epidermal Growth Factor-like (EGF-like) domains in human and 4-7 EGF-like domains in the mouse.^[15]
