OverviewNCBI Gene

Involved in several processes, including positive regulation of GTPase activity; positive regulation of epithelial cell proliferation involved in wound healing; and positive regulation of macromolecule metabolic process. Located in several cellular components, including extracellular space; mitotic spindle; and nucleoplasm. [provided by Alliance of Genome Resources, Jul 2025]

LocalizationUniProt · AlphaFold · HPA

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

Genetic constraint and essentialitygnomAD · DepMap

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

ODAM is annotated as secreted, so native ODAM circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label ODAM as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
