EGF module-containing mucin-like hormone receptor
G protein-coupled receptor
From Wikipedia, the free encyclopedia
The EGF module-containing Mucin-like hormone Receptors (EMRs) are closely related subgroup of G protein-coupled receptors (GPCRs). These receptors have a unique hybrid structure in which an extracellular epidermal growth factor (EGF)-like domain is fused to a GPCR domain through a mucin-like stalk.[1][2][3][4] There are four variants of EMR labeled 1–4, each encoded by a separate gene. These receptors are predominantly expressed in cells of the immune system and bind ligands such as CD55.[5]
