OverviewNCBI Gene
The protein encoded by this gene is a basic helix-loop-helix type transcription factor and shares similarity with Twist. This protein may inhibit osteoblast maturation and maintain cells in a preosteoblast phenotype during osteoblast development. This gene may be upregulated in certain cancers. Mutations in this gene cause focal facial dermal dysplasia 3, Setleis type. Two transcript variants encoding the same protein have been found. [provided by RefSeq, Apr 2014]

Whether an antibody against TWIST2 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 TWIST2 as an antibody target. Whether an autoantibody or antibody against TWIST2 could matter depends on whether native TWIST2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TWIST2 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 TWIST2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
