OverviewNCBI Gene
This gene encodes a DNA-binding protein with a gcm-motif (glial cell missing motif). The encoded protein is a homolog of the Drosophila glial cells missing gene (gcm). This protein binds to the GCM-motif (A/G)CCCGCAT, a novel sequence among known targets of DNA-binding proteins. The N-terminal DNA-binding domain confers the unique DNA-binding activity of this protein. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads GCM1 as an antibody target. Whether an autoantibody or antibody against GCM1 could matter depends on whether native GCM1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
GCM1 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 GCM1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
