OverviewNCBI Gene

This gene encodes a class I seven-transmembrane G-protein-coupled receptor. The encoded protein is a receptor for angiotensin-(1-7) and preferentially couples to the Gq protein, activating the phospholipase C signaling pathway. The encoded protein may play a role in multiple processes including hypotension, smooth muscle relaxation and cardioprotection by mediating the effects of angiotensin-(1-7).

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against MAS1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads MAS1 as an antibody target. Whether an autoantibody or antibody against MAS1 could matter depends on whether native MAS1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

MAS1 is annotated at the cell surface, where native MAS1 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 MAS1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
