OverviewNCBI Gene

Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen. The human genome has a cluster of several amylase genes that are expressed at high levels in either salivary gland or pancreas. This gene encodes an amylase isoenzyme produced by the salivary gland.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads AMY1C as an antibody target. Whether an autoantibody or antibody against AMY1C could matter depends on whether native AMY1C is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

AMY1C is annotated as secreted, so native AMY1C circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label AMY1C as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
