产品介绍
细胞粘附蛋白(Call Adhesion Protein) β连环素蛋白β-catenin是一种多功能的蛋白质,能链接E-\N-,钙粘附分子具有参与细胞粘附和介导信号转导的双重功能,并与肿瘤的发生发展及浸润密切相关。 在正常个体中,β-catenin和钙黏蛋白形成复合体,介导同型细胞的粘附,维持细胞的稳定;同时,β-catenin作为Wnt/β-catenin信号通路的关键成员在介导信号转导过程中调控细胞的增殖和凋亡。 在恶性肿瘤中,β-catenin的表达呈现明显的异质性,促使细胞异常增殖,还可使细胞之间的黏附性减弱,侵袭性增强。
This gene encodes not only an important cytoplasmic component of the classical cadherin adhesion complex that forms the adherens junction in epithelia and mediates cell-cell adhesion in many other tissues but also a key signaling molecule in the canonical Wnt signaling pathway that controls cell growth and differentiation during both normal development and tumorigenesis. The gene product contains a central armadillo-repeat containing domain through which it binds the cytoplasmic tail of classical cadherins; meanwhile, it also binds alpha-catenin, which further links the cadherin complex to the actin cytoskeleton either directly or indirectly. Beta-catenin is therefore necessary for the adhesive function of classical cadherins. Another key function of this protein is to mediate the canonical Wnt signaling pathway and regulate gene transcription. Without Wnt signal, cytoplasmic beta-catenin that is not associated with the cadherin complex is quickly phosphorylated at the N-terminal Ser/Thr residues by the so called degradation complex containing axin, adenomatous polyposis coli (APC), casein kinase I, and GSK3B, then ubiquitylated by beta-TrCP, and degraded by the proteasome. However, in the presence of Wnt signal, the degradation complex is disrupted and the stabilized cytoplasmic beta-catenin translocates into the nucleus, where it binds various transcription factors and, together with these factors, regulates the transcription of many downstream genes. Mutations of this gene have been linked with various types of tumors. Alternatively spliced variants have been found for this gene.
