OverviewNCBI Gene
This gene belongs to the melastatin subfamily of transient receptor potential family of ion channels. The protein encoded by this gene is both an ion channel and a serine/threonine protein kinase. The kinase activity is essential for the ion channel function, which serves to increase intracellular calcium levels and to help regulate magnesium ion homeostasis. The encoded protein is involved in cytoskeletal organization, cell adhesion, cell migration and organogenesis. Defects in this gene are a cause of amyotrophic lateral sclerosis-parkinsonism/dementia complex of Guam. The gene may also be associated with defects of cardiac function.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads TRPM7 as an antibody target. Whether an autoantibody or antibody against TRPM7 could matter depends on whether native TRPM7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TRPM7 is annotated at the cell surface, where native TRPM7 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 TRPM7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
