S100A8 Antibody / MRP8

S100 calcium-binding protein A8 is a protein that in humans is encoded by the S100A8 gene. It is also known as Calgranulin A, MRP8 and Calprotectin L1L subunit. The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in the inhibition of casein kinase and as a cytokine. Altered expression of this protein is associated with the disease cystic fibrosis.
