Human S100A3 protein, His tag

The protein encoded by this gene is a member of the S1 family of proteins containing 2 EF-hand calcium-binding motifs. S1 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. S1 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein has the highest content of cysteines of all S1 proteins, has a high affinity for Zinc, and is highly expressed in human hair cuticle. The precise function of this protein is unknown.
