General description
Protein S100-A8/9 (UniProt: P05109/ P06702; also known as MRP-8/MRP-14, Leukocyte L1 complex light chain/ Leukocyte L1 complex heavy chain, p8/p14, S100 calcium-binding protein A8/A9) are encoded by the S100A8/S100A9 (also known as MRP8/MRP14) genes (Gene ID: 6279/6280) in human. MRP-8 and MRP-14 are calcium- and zinc-binding protein that play a prominent role in the regulation of inflammatory processes and immune response. They are known to induce neutrophil chemotaxis and adhesion. They are predominantly found as calprotectin and perform a variety of intra- and extracellular functions. Their intracellular functions include facilitating leukocyte arachidonic acid trafficking and metabolism, modulation of the tubulin-dependent cytoskeleton during migration of phagocytes, and activation of the neutrophilic NADPH-oxidase. They are known to activate NADPH-oxidase by facilitating the enzyme complex assembly at the cell membrane. MRP-8 contributes to the enzyme assembly by directly binding to NCF2/P67PHOX. Their extracellular functions include proinflammatory, antimicrobial, oxidant-scavenging and induction of apoptosis. MRP-14 is reported to induce neutrophil chemotaxis and adhesion and can increase the bactericidal activity of neutrophils by promoting phagocytosis via activation of SYK, PI3K/AKT, and ERK1/2 pathways and can induce degranulation of neutrophils by a MAPK-dependent mechanism. MRP-8 and MRP-14 also acts as danger associated molecular pattern (DAMP) molecules and stimulate innate immune cells via binding to pattern recognition receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced glycation end (AGER) products. They also play an impotent role as oxidant scavengers and have a protective role in preventing exaggerated tissue damage by scavenging oxidants. (Ref.: Atallah, M., et al. (2012).
