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