Cell autonomous antagonist of the canonical Wnt signaling pathway. May activate a second Wnt signaling pathway that controls planar cell polarity. Required for processing of TGFA and for targeting of TGFA to the basolateral membrane of polarized epithelial cells. Interacts with DVL1, DVL2, DVL3 and PPP2R3A. Interacts with RNF25 and TGFA (via cytoplasmic domain). Expressed in kidney, lung, pancreas and spleen. Belongs to the NKD family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Cell development/differentiation; Ubiquitin conjugating system
