S100 calcium binding protein A13 (S100A13) is a member of the S100 family of calcium-binding proteins, characterized by two EF-hand motifs and unique amphiphilic alpha-helices. It is widely expressed across various tissues, with particularly high levels in the thyroid gland. S100A13 plays a specialized role in the alternative secretory pathway, where it facilitates the export of proteins lacking a signal peptide, such as interleukins and fibroblast growth factors. This process is dependent on its ability to bind both calcium and copper ions. Intracellularly, S100A13 localizes to the nucleus and stress fibers, where it regulates cell cycle progression, differentiation, and motility. Clinically, S100A13 is recognized as a novel marker for angiogenesis and is associated with the progression of lung cancer and trachea leiomyoma. Its essential role in the stress-induced secretion of pro-angiogenic and pro-inflammatory factors underscores its significance in tissue remodeling and tumor microenvironment dynamics.
