OverviewNCBI Gene

This gene encodes a member of a family of proteins containing a ribonucleoprotein (RNP)-type RNA binding motif and a carboxyl-terminal arginine-serine-rich (RS) domain. The encoded protein functions as a pre-mRNA splicing factor. There is a pseudogene for this gene on chromosome 7. Alternative splicing results in multiple transcript variants.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SRSF8 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 SRSF8 as an antibody target. Whether an autoantibody or antibody against SRSF8 could matter depends on whether native SRSF8 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SRSF8 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 SRSF8 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
