OverviewNCBI Gene

This gene encodes a CGG repeat-binding protein that primarily localizes to the nucleus. CGG trinucleotide repeats are implicated in many disorders as they often act as transcription- and translation-regulatory elements, can produce hairpin structures which cause DNA replication errors, and form regions prone to chromosomal breakage. CGG repeats are also targets for CpG methylation. In addition to its ability to bind CGG repeats and regulate transcription, this gene is believed to play a role in DNA damage repair and telomere protection. In vitro studies indicate this protein does not bind to methylated CpG sequences. [provided by RefSeq, Jul 2017]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CGGBP1 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 CGGBP1 as an antibody target. Whether an autoantibody or antibody against CGGBP1 could matter depends on whether native CGGBP1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CGGBP1 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 CGGBP1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
