OverviewNCBI Gene
This protein is a member of the keratin-associated protein (KAP) family. The KAP proteins form a matrix of keratin intermediate filaments which contribute to the structure of hair fibers. KAP family members appear to have unique, family-specific amino- and carboxyl-terminal regions and are subdivided into three multi-gene families according to amino acid composition: the high sulfur, the ultrahigh sulfur, and the high tyrosine/glycine KAPs. This protein is a member of the ultrahigh sulfur KAP family and the gene is localized to a cluster of KAPs at 17q12-q21. [provided by RefSeq, Mar 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads KRTAP4-7 as an antibody target. Whether an autoantibody or antibody against KRTAP4-7 could matter depends on whether native KRTAP4-7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
KRTAP4-7 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 KRTAP4-7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
