Mouse S100A8 (also CP-10, calgranulin A and MRP8) is a 10kD member of the S100 family of calcium-binding proteins. The S100A8 protein is 89 amino acids (aa) in length and contains short, sequential modules. There is an N-terminal a-helix, followed by a calcium-binding EF-hand segment, and a C-terminal a-helix. S100A8 will noncovalently heterodimerize with S100A9. In the presence of calcium, this heterodimer will form a heterotetramer. The dimeric complex is both intracellular and extracellular. It binds heparan sulfate and is chemotactic for PMNs and macrophages. Mouse S100A8 is 80% and 57% aa identical to rat and human S100A8, respectively.
