OverviewNCBI Gene

Cofactor C is one of four proteins (cofactors A, D, E, and C) involved in the pathway leading to correctly folded beta-tubulin from folding intermediates. Cofactors A and D are believed to play a role in capturing and stabilizing beta-tubulin intermediates in a quasi-native confirmation. Cofactor E binds to the cofactor D/beta-tubulin complex; interaction with cofactor C then causes the release of beta-tubulin polypeptides that are committed to the native state.

LocalizationUniProt · AlphaFold · HPA

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

TBCC is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

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