S100A15A, a member of the S100 family of calcium-binding proteins, plays diverse roles in cellular regulation and immune responses. This protein, encoded by the *S100A15A* gene (also termed *S100A7A* in humans), is structurally characterized by two EF-hand calcium-binding motifs and exists as a homodimer. It is predominantly expressed in epithelial tissues, particularly the skin, and is implicated in inflammation, differentiation, and antimicrobial defense. Notably, S100A15A exhibits species-specific functional divergence; for example, human S100A15A shares homology with mouse S100A15 but differs in cellular localization and secretion pathways.
Recombinant S100A15A is produced via genetic engineering, typically using bacterial (e.g., *E. coli*) or mammalian expression systems, to enable functional and structural studies. The recombinant protein retains calcium-binding capacity and interacts with receptors like RAGE (Receptor for Advanced Glycation End-products), modulating intracellular signaling pathways such as NF-κB and MAPK. Its expression is upregulated in inflammatory skin disorders, including psoriasis and atopic dermatitis, where it contributes to chemotaxis of immune cells and amplifies pro-inflammatory cytokine production.
Research on recombinant S100A15A also explores its dual role as both an intracellular regulator and an extracellular alarmin, released during tissue stress to activate innate immunity. Challenges in studying endogenous S100A15A, such as low abundance and cross-reactivity with related S100 proteins, make the recombinant form critical for elucidating its mechanisms. Current studies focus on its potential as a therapeutic target or biomarker in chronic inflammation and cancer, given its involvement in tumor microenvironment modulation. However, its pleiotropic effects necessitate careful evaluation of context-dependent functions in disease models.
