Recombinant human CTNNA2 (Catenin Alpha-2) protein is a key component in studying cell-cell adhesion and signaling pathways. CTNNA2 belongs to the α-catenin family, which links cadherin-based adherens junctions to the actin cytoskeleton, maintaining tissue integrity and regulating cell polarity, migration, and proliferation. Unlike ubiquitously expressed CTNNA1. CTNNA2 is predominantly found in neuronal tissues, where it plays a role in synaptic plasticity, dendritic spine formation, and neural circuit development. Its gene, located on chromosome 2p12-p11.1. has been implicated in neurodevelopmental disorders, including autism spectrum disorders and intellectual disabilities, as well as cancers due to dysregulated cell adhesion and signaling.
Recombinant CTNNA2 is typically produced in prokaryotic (e.g., *E. coli*) or eukaryotic systems (e.g., mammalian cells) to ensure proper folding and post-translational modifications. This engineered protein retains functional domains, such as vinculin-binding and actin-regulating motifs, enabling in vitro studies on mechanotransduction, neuronal connectivity, and tumor suppression mechanisms. Researchers use it to explore CTNNA2’s interactions with β-catenin, cadherins, and cytoskeletal proteins, as well as its role in Wnt signaling and cancer metastasis. Its applications extend to drug screening, disease modeling, and elucidating molecular pathways in neurodevelopmental and oncological research.
