DACT1 (Dishevelled-Binding Antagonist of Beta-Catenin 1) is a protein involved in the Wnt signalling pathway, which is essential for regulating embryonic development, cell growth, and differentiation. By modulating Wnt signalling, 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.
