OverviewNCBI Gene

The globular WW domain is composed of 38 to 40 semiconserved amino acids shared by proteins of diverse functions including structural, regulatory, and signaling proteins. The domain is involved in mediating protein-protein interactions through the binding of polyproline ligands. This gene encodes a WW domain binding protein. This gene also encodes a domain with similarity to the transcription elongation factor A, SII-related family. Alternative splicing results in multiple transcript variants encoding a single isoform.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TCEAL9 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads TCEAL9 as an antibody target. Whether an autoantibody or antibody against TCEAL9 could matter depends on whether native TCEAL9 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TCEAL9 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 TCEAL9 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
