OverviewNCBI Gene

This gene encodes a molecular chaperone that is a member of the chaperonin containing TCP1 complex (CCT), also known as the TCP1 ring complex (TRiC). This complex consists of two identical stacked rings, each containing eight different proteins. Unfolded polypeptides enter the central cavity of the complex and are folded in an ATP-dependent manner. The complex folds various proteins, including actin and tubulin. Alternative splicing results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 5 and 6. [provided by RefSeq, Oct 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CCT7 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 CCT7 as an antibody target. Whether an autoantibody or antibody against CCT7 could matter depends on whether native CCT7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CCT7 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 CCT7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
