OverviewNCBI Gene
Enables ubiquitin protein ligase binding activity. Involved in several processes, including positive regulation of cellular component organization; positive regulation of double-strand break repair; and protein localization to site of double-strand break. Located in PML body; chromatin; and site of double-strand break. Implicated in mosaic variegated aneuploidy syndrome. [provided by Alliance of Genome Resources, Jul 2025]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SLF2 as an antibody target. Whether an autoantibody or antibody against SLF2 could matter depends on whether native SLF2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLF2 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 SLF2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
