OverviewNCBI Gene
This gene encodes an essential component of the telomerase holoenzyme complex, a ribonucleoprotein complex required for telomere synthesis. This protein is enriched in Cajal bodies, nuclear sites of RNP processing that are important for telomerase function. It interacts with dyskerin, TERT and TERC, other components of active telomerase, and with small Cajal body RNAs (scaRNAs), which are involved in modifying splicing RNAs. This mRNA also functions as a p53 antisense transcript, that regulates endogenous p53 mRNA levels and further induction of p53 protein by targeting the 5' untranslated region of p53 mRNA. Alternatively spliced transcript variants which differ only in the 5' UTR have been found for this gene. [provided by RefSeq, Mar 2011]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads WRAP53 as an antibody target. Whether an autoantibody or antibody against WRAP53 could matter depends on whether native WRAP53 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
WRAP53 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 WRAP53 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
