OverviewNCBI Gene
The protein encoded by this gene is a receptor for monocyte chemoattractant protein-1, a chemokine which specifically mediates monocyte chemotaxis. Monocyte chemoattractant protein-1 is involved in monocyte infiltration in inflammatory diseases such as rheumatoid arthritis as well as in the inflammatory response against tumors. The encoded protein mediates agonist-dependent calcium mobilization and inhibition of adenylyl cyclase. This protein can also be a coreceptor with CD4 for HIV-1 infection. This gene is located in the chemokine receptor gene cluster region of chromosome 3. [provided by RefSeq, Aug 2017]

Whether an antibody against CCR2 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads CCR2 as an antibody target. Whether an autoantibody or antibody against CCR2 could matter depends on whether native CCR2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
CCR2 is annotated at the cell surface, where native CCR2 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label CCR2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
