OverviewNCBI Gene

SHQ1 assists in the assembly of H/ACA-box ribonucleoproteins that function in the processing of ribosomal RNAs, modification of spliceosomal small nuclear RNAs, and stabilization of telomerase (see MIM 602322) (Grozdanov et al., 2009 [PubMed 19383767]).[supplied by OMIM, Dec 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SHQ1 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 SHQ1 as an antibody target. Whether an autoantibody or antibody against SHQ1 could matter depends on whether native SHQ1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SHQ1 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 SHQ1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
