Function [link]

This gene encodes a protein that is a member of the adhesion-GPCR family ^[5] . Family members are characterized by an extended extracellular region with a variable number of protein domains coupled to a TM7 domain via a mucin-like spacer region. In the case of EMR1 these domains are Epidermal Growth Factor (EGF)-like domains.

Emr1 is a transmembrane protein present on the cell-surface of human macrophages, which are derived from the myeloid lineage. It has an approximate mass of 125 kDa, and is associated with mature macrophages.
