Calprotectin is abundantly found in neutrophils, it comprises nearly 60% of soluble proteins in the cytoplasm of these immune cells. It belongs to the larger S100 family of EF-hand calcium-binding proteins but has unique functions attributable to its heterodimeric structure of S100A8 and S100A9 subunits.
