OverviewNCBI Gene
The protein encoded by this gene belongs to a family of proteins that are homologous to yeast Sec24. This protein is a component of coat protein II (COPII)-coated vesicles that mediate protein transport from the endoplasmic reticulum. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the golgi complex. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SEC24A as an antibody target. Whether an autoantibody or antibody against SEC24A could matter depends on whether native SEC24A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SEC24A 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 SEC24A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
