关于 S100A3

功能概要

由该基因编码的蛋白质是包含 2 个 EF 手钙结合基序的 S100 蛋白质家族的成员。 S100 蛋白定位于多种细胞的细胞质和/或细胞核，并参与许多细胞过程的调节，例如细胞周期进程和分化。 S100 基因包括至少 13 个成员，它们成簇地位于染色体 1q21 上。该蛋白是所有 S100 蛋白中半胱氨酸含量最高的，对锌具有很高的亲和力，在人的毛发角质层中高表达。这种蛋白质的确切功能是未知的。[RefSeq 提供，2008 年 7 月]

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 has the highest content of cysteines of all S100 proteins, has a high affinity for Zinc, and is highly expressed in human hair cuticle. The precise function of this protein is unknown.
