OverviewNCBI Gene

This gene encodes a member of the trypsin family of serine proteases. This gene and several related trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7. This gene was previously described as a trypsinogen-like pseudogene, but it is now thought to be a protein-coding gene. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against PRSS58 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 PRSS58 as an antibody target. Whether an autoantibody or antibody against PRSS58 could matter depends on whether native PRSS58 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PRSS58 is annotated as secreted, so native PRSS58 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label PRSS58 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
