OverviewNCBI Gene
This gene encodes a scaffold protein which serves as an assessory factor to the nuclear RNA exosome complex. The encoded protein forms a trimeric human nuclear exosome targeting (NEXT) complex, together with hMTR4 and the RNA-binding factor RBM7 which promotes the exosomal degradation of non-coding promoter-upstream transcripts, enhancer RNAs and 3'-extended products of histone- and small nuclear RNA transcription. This complex is also thought to recruit the exosome to degrade intronic RNAs via its interaction with both the exosome and the spliceosome. It contains both an N-terminal zinc-knuckle domain and a C-terminal proline-rich domain. [provided by RefSeq, Apr 2017]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ZCCHC8 as an antibody target. Whether an autoantibody or antibody against ZCCHC8 could matter depends on whether native ZCCHC8 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ZCCHC8 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 ZCCHC8 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
