OverviewNCBI Gene
This gene likely encodes a member of the arginine/serine-rich splicing factor family. A similar protein in Rat appears to bind the large subunit of RNA polymerase II and provide a link between transcription and pre-mRNA splicing. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SCAF4 as an antibody target. Whether an autoantibody or antibody against SCAF4 could matter depends on whether native SCAF4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SCAF4 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 SCAF4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
