OverviewNCBI Gene
The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase contains multiple functional domains. Its kinase domain is highly similar to that of the myotonic dystrophy protein kinase (DMPK). This kinase also contains a Rac interactive binding (CRIB) domain, and has been shown to bind CDC42. It may function as a CDC42 downstream effector mediating CDC42 induced peripheral actin formation, and promoting cytoskeletal reorganization. Multiple alternatively spliced transcript variants have been described. [provided by RefSeq, Sep 2018]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads CDC42BPA as an antibody target. Whether an autoantibody or antibody against CDC42BPA could matter depends on whether native CDC42BPA is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
CDC42BPA is annotated at the cell surface, where native CDC42BPA is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label CDC42BPA as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
