EGF-like module-containing mucin-like hormone receptor-like 3 is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, res ...

gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...

EMR3 is a member of the
adhesion GPCR family.
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.
EMR3 expression is restricted to monocytes/macrophages, myeloid dendritic cells, and mature granulocytes in human. Transcription of the EMR3 gene results in two alternative spliced forms: a surface protein with extracellular, 7TM, and intracellular domains as well as a truncated soluble form of only the extracellular domain.
Mice, next to Emr2, lack the Emr3 gene.
Function
The protein may play a role in
myeloid
Myeloid tissue, in the bone marrow sense of the word '' myeloid'' ('' myelo-'' + '' -oid''), is tissue of bone marrow, of bone marrow cell lineage, or resembling bone marrow, and myelogenous tissue (''myelo-'' + '' -genous'') is any tissue o ...
-myeloid interactions during immune and inflammatory responses.
Ligands
A potential ligand of EMR3 likely is expressed on human macrophage and activated neutrophils.
