OverviewNCBI Gene

This gene encodes a soluble, cytoplasmic, tyrosine-phosphorylated protein with multiple ubiquitin-interacting domains. Mutations in this gene cause nonsyndromic, postlingual, progressive sensorineural DFNA44 hearing loss. In mouse, the protein is expressed in the inner ear during development and postnatal maturation and associates with microtubule-based structures. This protein may also function as a negative regulator of NF-kB signaling and as an effector of epidermal growth factor (EGF)-mediated cell signaling. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Oct 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CCDC50 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 CCDC50 as an antibody target. Whether an autoantibody or antibody against CCDC50 could matter depends on whether native CCDC50 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CCDC50 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 CCDC50 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
