EMR3

EGF-like module-containing mucin-like hormone receptor-like 3 is a protein encoded by the ADGRE3 gene.[3][4] EMR3 is a member of the adhesion GPCR family.[5][6] 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.[7]

EMR3 expression is restricted to monocytes/macrophages, myeloid dendritic cells, and mature granulocytes in human.[8] 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.[9] Mice, next to Emr2, lack the Emr3 gene.[10]

Function

The protein may play a role in myeloid-myeloid interactions during immune and inflammatory responses.[11]

Ligands

A potential ligand of EMR3 likely is expressed on human macrophage and activated neutrophils.[9]

gollark: Stuff like my password manager information can't practically be stored elsewhere.
gollark: I have backups (ish). I'm concerned about unauthorized access to it more than losing it.
gollark: I do, in fact, have somewhat important things on my computer.
gollark: I want hardware and software which is less likely to randomly leak information or have security flaws. It's *really* bad for cloud providers.
gollark: And more bizarre artificial segmentation with overclocking and RAM speeds.
