Catenin alpha-1 Antibody (PA1-25081) in WB
Western blot was performed using Anti-Catenin alpha-1 Polyclonal Antibody(Product # PA1-25081) and a 100kDa band corresponding to Catenin alpha-1 was observed across cell lines and tissue extracts tested except PC-3 and Daudi which is reported to be negative. A non-specific band around 160kDA has also been observed in cell lines. Whole Cell Extract-WCL (30 µg lysate) of A-431 (Lane 1), HeLa (Lane 2), MCF7 (Lane 3), LNCaP (Lane 4), PC-3 (Lane 5), Daudi (Lane 6), NIH/3T3 (Lane 7), PC-12 (Lane 8) and tissue extracts of Mouse Lung (Lane 9), Mo...

Target Information
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 adherence 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.
