Positive regulator of the Wnt signaling pathway that specifically cleaves 'Lys-63'-linked ubiquitin chains. Acts by deubiquitinating APC protein, a negative regulator of Wnt-mediated transcription. May play a role in the regulation of cell morphology and cytoskeletal organization. Required in the stress fiber dynamics and cell migration (By similarity).
