DACT1 (Dishevelled-Binding Antagonist of Beta-Catenin 1) is a protein involved in the Wnt signaling pathway, which is crucial for regulating embryonic development, cell growth, and differentiation. By modulating Wnt signaling, DACT1 helps control key processes in tissue development and maintenance. Alterations in DACT1 activity have been associated with various cancers, underscoring its role in cell proliferation and making it a key focus of cancer research.
