ADGRE3 Membrane Protein Introduction

Introduction of ADGRE3

ADGRE3, also known as EGF-like module receptor 3 (EMR3) or EGF-like module-containing mucin-like hormone receptor-like 3, is a protein encoded by the human ADGRE3 gene. As a member of the adhesion GPCR family, ADGRE3 is expressed at the cell surface as a heterodimeric molecule consisting of a long extracellular α-chain, which possesses an N-terminus EGF-like domain and a membrane-spanning β-chain.

Function of ADGRE3 Membrane Protein

ADGRE3 is a poorly characterized EGF-TM7 receptor which possesses two EGF domains and has been suggested to bind a ligand at the surface of monocyte-derived macrophages and activated neutrophils. It is remarkable that the TM7 region of ADGRE3 is highly similar to that of EMR2, and in fact, EMR3 was discovered unintentionally as a PCR co-amplification product during the cDNA cloning of EMR2. Studies have shown that the expression of ADGRE3 is restricted to mature monocytes/macrophages, myeloid dendritic cells, and mature granulocytes in human. Although the cellular distribution of EMR3 partially overlaps with that of CD97 and EMR2, it is absent from hematopoietic stem and progenitor cells. What’s more, it has been reported that ADGRE3 plays a role in myeloid-myeloid interactions during immune and inflammatory responses.

Application of ADGRE3 Membrane Protein in Literature

1. Kane AJ, EMR3: A Potential Mediator of Invasive Phenotypic Variation in Glioblastoma and Novel Therapeutic Target. Neuroreport. 2010, 21(16): 1018-22. PubMed ID: 20827226

This article reveals that EMR-3 is variably expressed in primary human glioblastoma tissues and cell lines. Knocking down EMR-3 has no impact on cellular proliferation, but decreases cellular invasion by greater than 3-fold. It indicates that EMR-3 may be used as a potential therapeutic target for glioma.

2. Matmati M, The human EGF-TM7 receptor EMR3 is a marker for mature granulocytes. Journal of leukocyte biology. 2007, 81(2): 440. PubMed ID: 17108056

This article reveals that the expression of EGF-TM7 receptors on myeloid cells is differentially regulated. EMR3 is the first family member found mainly on granulocytes.

3. Stacey M, Human epidermal growth factor (EGF) module-containing mucin-like hormone receptor 3 is a new member of the EGF-TM7 family that recognizes a ligand on human macrophages and activated neutrophils. Journal of Biological Chemistry. 2001, 276(22): 18863-70. PubMed ID: 11279179

This article suggests that EMR3 plays a role in myeloid-myeloid interactions during immune and inflammatory responses.
