LocalizationUniProt · AlphaFold · HPA

Whether an antibody against C3P1 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 reachability: Secreted
Secreted: Yes
Transmembrane segments: 0
Mean surface accessibility (rSASA): 0.35

Cancer expressionTCGA

Across TCGA tumor cohorts, this protein is over-expressed in roughly 2% of surveyed tumor types (aggregate summary; per-cohort expression, alteration, and survival load in the interactive view).

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads C3P1 as an antibody target. Whether an autoantibody or antibody against C3P1 could matter depends on whether native C3P1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

C3P1 is annotated as secreted, so native C3P1 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 C3P1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
