OverviewNCBI Gene

This gene encodes a human homolog of Drosophila splicing regulatory protein. This gene autoregulates its expression by control of splicing of its first two introns. In addition, it also regulates the splicing of fibronectin and CD45 genes. Two transcript variants encoding different isoforms have been identified. [provided by RefSeq, May 2012]

Antibody and autoantibody relevanceSeroatlas analysis

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

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