Background of the antigen
This gene encodes a member of the "fused gene" family of proteins, which contain N terminus EF hand domains and multiple tandem peptide repeats. The encoded protein contains two EF hand Ca2+ binding domains in its N terminus and two glutamine and threonine rich 60 amino acid repeats in its C terminus. This gene, also known as squamous epithelial heat shock protein 53, may play a role in the mucosal/epithelial immune response and epidermal differentiation.
