抗原名称 S100B
背景介绍 S100 beta 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 21q22.3. This protein may function in neurite extension, proliferation of melanoma cells, stimulation of Ca2+ fluxes, inhibition of PKC mediated phosphorylation, astrocytosis and axonal proliferation, and inhibition of microtubule assembly. Chromosomal rearrangements and altered expression of this gene have been implicated in several neurological, neoplastic, and other types of diseases, including Alzheimer's disease, Down's syndrome, epilepsy, amyotrophic lateral sclerosis, melanoma, and type I diabetes.
细胞定位 细胞核、细胞浆
结构特征 每 个 S100 蛋白由 2 个EF-手型钙结合部位组成,中间由 1 个连接器连接,第一个结合部位由螺旋Ⅰ( 钙离子结合部位) 和螺旋Ⅱ组成,具有较弱的钙离子结合能力,而第二个结合部位由螺旋Ⅲ-环-螺旋Ⅳ组成,具有较高的钙离子结合力。
功能 参与细胞增殖、分化、肌肉收缩、基因表达、分泌及细胞凋亡等过程,还有神经营养、信号调节因子的作用
研究领域 肿瘤 细胞生物 免疫学 神经生物学 信号转导 细胞周期蛋白
