OverviewNCBI Gene
Enables alpha-tubulin binding activity; beta-tubulin binding activity; and kinase activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; negative regulation of microtubule depolymerization; and positive regulation of MAPK cascade. Located in several cellular components, including microtubule cytoskeleton; nuclear body; and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Jul 2025]

Whether an antibody against TAOK1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Protein binding partners of TAOK1 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads TAOK1 as an antibody target. Whether an autoantibody or antibody against TAOK1 could matter depends on whether native TAOK1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TAOK1 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 TAOK1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
