OverviewNCBI Gene

This gene encodes a member of the HMG-box DNA-binding protein family. The encoded protein plays a critical role in ribosomal RNA transcription as a key component of the pre-initiation complex, mediating the recruitment of RNA polymerase I to rDNA promoter regions. The encoded protein may also play important roles in chromatin remodeling and pre-rRNA processing, and its activity is regulated by both phosphorylation and acetylation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. Pseudogenes of this gene are located on the short arm of chromosomes 3, 11 and X and the long arm of chromosome 11. [provided by RefSeq, Aug 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against UBTF can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Four sources answering four different questions about UBTF.

Disease | AllUniProt

Conditions UBTF is implicated in, by any mechanism.

Disease | GeneticClinVar

7 pathogenic / likely-pathogenic of 194 ClinVar records.

Conditions with pathogenic or likely-pathogenic variants.

Disease | AutoantibodyPubMed

Conditions in which antibodies against UBTF are reported. Each links to that disease's full target list.

ReferencesPubMed · IEDB

Publications for UBTF from three distinct lines of evidence, kept separate because they answer different questions: whether antibodies are directed at the protein, whether a B-cell epitope has been mapped on it, and whether a T-cell epitope has. Each is labelled with its source.

Sources: PubMed — antigen-level antibody evidence from a custom retrieval. Records matching a controlled set of autoantibody terms (the MeSH descriptors Autoantibodies and Autoantigens, with title and abstract term variants) were obtained through NCBI E-utilities, and their titles and abstracts parsed for constructions that direct an antibody at a named protein rather than for co-occurrence. Captured names were resolved against UniProt nomenclature and each antigen adjudicated individually against the source text. Bibliographic records from PubMed and MeSH, U.S. National Library of Medicine; citation metrics from NIH iCite (Hutchins et al., PLoS Biology 2016). Titles link to PubMed; abstracts are not reproduced here. The NLM does not endorse this analysis.

Antibody and autoantibody relevanceSeroatlas analysis

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

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