OverviewNCBI Gene
This gene encodes a protein that is involved as a negative regulator of GSK3-beta in the Wnt signaling pathway. The encoded protein may play a role in the retinoic acid signaling pathway by regulating the functional interactions between GSK3-beta, beta-catenin and cyclin D1, and it regulates the beta-catenin/N-cadherin pool. The encoded protein contains a GSK3-beta interacting domain (GID) in its C-terminus, which is similar to the GID of Axin. The protein also contains an evolutionarily conserved RII-binding domain, which facilitates binding with protein kinase-A and GSK3-beta, enabling its role as an A-kinase anchoring protein. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Dec 2012]

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