OverviewNCBI Gene

This gene encodes a member of the never in mitosis gene A family of kinases. The encoded protein localizes to the nucleoli, and may function with NEK2A in the S-phase checkpoint. The encoded protein appears to play roles in DNA replication and response to genotoxic stress. Alternatively spliced transcript variants have been described.[provided by RefSeq, Mar 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against NEK11 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 NEK11 as an antibody target. Whether an autoantibody or antibody against NEK11 could matter depends on whether native NEK11 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

NEK11 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 NEK11 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
