OverviewNCBI Gene
The protein encoded by this gene is found in brush border microvilli of epithelial cells in the intestines and kidneys. The encoded protein is involved in linking protocadherins to the actin cytoskeleton and is essential for proper microvilli function. This protein aids in the accumulation of intermicrovillar adhesion components such as harmonin and ANKS4B, and this accumulation is necessary for normal brush border action.

Protein binding partners of MYO7B 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 MYO7B as an antibody target. Whether an autoantibody or antibody against MYO7B could matter depends on whether native MYO7B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
MYO7B 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 MYO7B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
