OverviewNCBI Gene
This gene encodes a protein which acts as a receptor for adiponectin, a hormone secreted by adipocytes which regulates fatty acid catabolism and glucose levels. Binding of adiponectin to the encoded protein results in activation of an AMP-activated kinase signaling pathway which affects levels of fatty acid oxidation and insulin sensitivity. A pseudogene of this gene is located on chromosome 14. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2014]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ADIPOR1 as an antibody target. Whether an autoantibody or antibody against ADIPOR1 could matter depends on whether native ADIPOR1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ADIPOR1 is annotated at the cell surface, where native ADIPOR1 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 ADIPOR1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
