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; however, this gene is located at 4p16. This protein, in addition to binding Ca2+, also binds Zn2+ and Mg2+. This protein may play a role in the etiology of prostate cancer.Store at 4°C. For long term storage, aliquot and store at -20°C. Avoid repeated freezing and thawing cycles. *   http://www.creative-diagnostics.com/Anti-S100P-PAb-Biotin-Conjugated-190953-491.htm
