Dishevelled binding antagonist of beta catenin 1 (original) (raw)

Dishevelled binding antagonist of beta catenin 1 (Dact1, previously known as Dapper, Dpr1, Frodo) is a protein that in humans is encoded by the DACT1 gene. Dact1 was originally described in 2002 as a negative regulator of Wnt signaling by binding and destabilizing Dishevelled. More recent investigation into the molecular function of Dact1 has identified its principle role in the cell as a scaffold to generate membrane-less biomolecular condensates through liquid-liquid phase separation. Mutations in the phase-separating regions of Dact1 lead to while its overexpression is associated with bone metastasis.
