| 产品介绍 |
The distinct peripheral cytosolic proteins, alpha, beta and gamma-catenin (102, 94 and 86 kDa) found in many tissues bind to the conserved cytoplasmic tail domain of the cell-adhesion cadherins. Catenins link E-cadherin to other integral membrane or cytoplasmic proteins and are modulated by Wnt-1 proto-oncogene. They are good candidates for mediating transduction of cell-cell contact positional signals to the cell interior. Absence of alpha-catenin is found in certain tumor cell lines and reduced levels in certain human carcinomas. Beta-catenin binds directly to the cytoplasmic tail of E-cadherin. It binds to the N-terminus of alpha-catenin and interacts with the protein product of the tumor suppressor gene APC. This interaction involves a 15-aa repeat in the APC. Beta-catenin cell levels seem to be controlled by APC. The central core region of beta-catenin is involved in mediation of cadherin-catenin complex interaction with EGFR. Function: Associates with the cytoplasmic domain of a variety of cadherins. The association of catenins to cadherins produces a complex which is linked to the actin filament network, and which seems to be of primary importance for cadherins cell-adhesion properties. Can associate with both E- and N-cadherins. Originally believed to be a stable component of E-cadherin/catenin adhesion complexes and to mediate the linkage of cadherins to the actin cytoskeleton at adherens junctions. In contrast, cortical actin was found to be much more dynamic than E-cadherin/catenin complexes and CTNNA1 was shown not to bind to F-actin when assembled in the complex suggesting a different linkage between actin and adherens junctions components. The homodimeric form may regulate actin filament assembly and inhibit actin branching by competing with the Arp2/3 complex for binding to actin filaments. May play a crucial role in cell differentiation. Subunit: Monomer and homodimer; the monomer preferentially binds to CTNNB1 and the homodimer to actin. Binds MLLT4 and F-actin. Possible component of an E-cadherin/ catenin adhesion complex together with E-cadherin/CDH1 and beta-catenin/CTNNB1 or gamma-catenin/JUP; the complex is located to adherens junctions. The stable association of CTNNA1 is controversial as CTNNA1 was shown not to bind to F-actin when assembled in the complex. Alternatively, the CTNNA1-containing complex may be linked to F-actin by other proteins such as LIMA1. Interacts with ARHGAP21 and with AJUBA. Interacts with LIMA1. Subcellular Location: Cytoplasm, cytoskeleton. Cell junction, adherens junction. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell junction. Note=Found at cell-cell boundaries and probably at cell-matrix boundaries. Tissue Specificity: Expressed ubiquitously in normal tissues. Post-translational modifications: Sumoylated. Similarity: Belongs to the vinculin/alpha-catenin family. SWISS: P35221 Gene ID: 1495 Database links: Entrez Gene: 1495 Human Entrez Gene: 12385 Mouse Omim: 116805 Human SwissProt: P35221 Human SwissProt: P26231 Mouse α-catenin是一种多功能的蛋白质，能链接E-\N-\P-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，βα-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，α-catenin作为Wnt/α-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，α-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。 |
