General annotation (Comments)

Function	Receptor for the MCP-1, MCP-3 and MCP-4 chemokines. Transduces a signal by increasing the intracellular calcium ions level. Alternative coreceptor with CD4 for HIV-1 infection.
Subunit structure	Binds to HIV-1 Tat.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Post-translational modification	N-glycosylated.
Polymorphism	Variations in CCR2 are associated with relative resistance to immunodeficiency virus type 1 (resistance to HIV-1) [MIM:609423].
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
