Backbone resonance assignments of the F-actin binding domain of mouse αN-catenin.

α-Catenin is a filamentous actin (F-actin) binding protein that links the classical cadherin-catenin complex to the actin cytoskeleton at adherens junctions (AJs). Its C-terminal F-actin binding domain is required for regulating the dynamic interaction between AJs and the actin cytoskeleton during tissue development. Thus, obtaining the molecular details of this interaction is a crucial step towards understanding how α-catenin plays critical roles in biological processes, such as morphogenesis, cell polarity, wound healing and tissue maintenance. Here we report the backbone atom (1HN, 15N, 13Cα, 13Cβ and 13C') resonance assignments of the C-terminal F-actin binding domain of αN-catenin.
