OverviewNCBI Gene
The protein encoded by this gene is a member of the RAMP family of single-transmembrane-domain proteins, called receptor (calcitonin) activity modifying proteins (RAMPs). RAMPs are type I transmembrane proteins with an extracellular N terminus and a cytoplasmic C terminus. RAMPs are required to transport calcitonin-receptor-like receptor (CRLR) to the plasma membrane. CRLR, a receptor with seven transmembrane domains, can function as either a calcitonin-gene-related peptide (CGRP) receptor or an adrenomedullin receptor, depending on which members of the RAMP family are expressed. In the presence of this (RAMP3) protein, CRLR functions as an adrenomedullin receptor. [provided by RefSeq, Jul 2008]

Whether an antibody against RAMP3 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 RAMP3 as an antibody target. Whether an autoantibody or antibody against RAMP3 could matter depends on whether native RAMP3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RAMP3 is annotated at the cell surface, where native RAMP3 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 RAMP3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
