sentences:  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.EMR2 is expressed by monocytes/macrophages, dendritic cells and all types of granulocytes.In the case of EMR2 the N-terminal domains consist of alternatively spliced epidermal growth factor-like (EGF-like) domains.
