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]

Function

Utilizing F4/80 knockout mice, Lin et al. showed that F4/80 is not necessary for the development of tissue macrophages but is required for the induction of efferent CD8+ regulatory T cells needed for peripheral tolerance.[16]

Clinical significance

Legrand et al. demonstrated that EMR1 can serve as a therapeutic target for depletion of these cells in eosinophilic disorders by using afucosylated antibodies.[17]
