OverviewNCBI Gene
This gene encodes a member of the peptidase M1 family. The encoded protein is an extracellular peptidase that specifically cleaves and inactivates the neuropeptide thyrotropin-releasing hormone.[provided by RefSeq, Dec 2008]

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