EGF-like module-containing mucin-like hormone receptor-like 2 is a protein that in humans is encoded by the EMR2 gene.^[1] EMR2 has also been designated as CD312 (cluster of differentiation 312).

This gene encodes a member of the class B seven-span transmembrane (TM7) receptor family expressed predominantly by cells of the immune system. Family members are characterized by an extended extracellular region with a variable number of N-terminal epidermal growth factor (EGF)-like domains coupled to a TM7 domain via a mucin-like spacer domain. This gene is closely linked to the gene encoding egf-like molecule containing mucin-like hormone receptor 3 on chromosome 19. This protein does not interact with the ligand decay accelerating factor for complement, unlike the related CD97 antigen, and indicates that these very closely related proteins likely have nonredundant functions. This gene results in multiple transcripts encoding distinct isoforms.^[1]
