Dishevelled is one of the multi-module proteins working in the Wnt pathway. The DIX domain in Axin is similar to a domain in Dishevelled, and may promote interacions between these two domains (Hsu 1999). The protein has been found at multiple locations in cells, including the nucleus (Itoh, 2005)
While the mechanism of action of Dsh is not known, it interacts with a number of other molecules, including Casein Kinase 1 (CK1e); Peters 1999, Sakanaka, 1999) Casein Kinase 2 (CK2; Willert 1997 Song, 2003) and GBP/Frat1 (Li L1999, Salic, 2000; Farr 2000). CK1 appears to be important for Wnt signaling, both in Xenopus and in C. elegans ( Peters 1999). It should be noted that CK1 and CK2 are unrelated kinases. A third kinase interacting with Dsh is Par-1 (Sun et al, 2001). This kinase acts as a positive regaulator of Wnt signaling in Drosophila and in other systems; and can phosphorylate Dsh directly. Ossipova et al. (2005) have suggested that PAR-1A and PAR-1BX are essential for canonical signaling to beta-catenin. Dsh also Regules Lethal giant larvae and cell polarity (Dollar, 2005). The KLHL12-Cullin-3 ubiquitin ligase has bene reported to target Dishevelled for degradation (Angers, 2006).
