OverviewNCBI Gene

This gene encodes a small salivary mucin, which is thought to play a role in facilitating the clearance of bacteria in the oral cavity and to aid in mastication, speech, and swallowing. The central domain of this glycoprotein contains tandem repeats, each composed of 23 amino acids. This antimicrobial protein has antibacterial and antifungal activity. The most common allele contains 6 repeats, and some alleles may be associated with susceptibility to asthma. Alternatively spliced transcript variants with different 5' UTR, but encoding the same protein, have been found for this gene. [provided by RefSeq, Oct 2014]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against MUC7 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads MUC7 as an antibody target. Whether an autoantibody or antibody against MUC7 could matter depends on whether native MUC7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

MUC7 is annotated as secreted, so native MUC7 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 MUC7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
