Description

The beta-catenin destruction complex plays a key role in the canonical Wnt signaling pathway. In the absence of Wnt signaling, this complex controls the levels of cytoplamic beta-catenin. Beta-catenin associates with and is phosphorylated by the destruction complex. Phosphorylated beta-catenin is recognized and ubiquitinated by the SCF-beta TrCP ubiquitin ligase complex and is subsequently degraded by the proteasome (reviewed in Kimelman and Xu, 2006).

SCF-beta-TrCP1 complex associated with phosphorylated beta-cateninComplexREACT_10593 (Reactome) B-TrCP associates with phosphorylated beta-catenin through the B-TrCP WD40 repeat region. Currently, it is unclear whether the ubiquitin ligase binds beta-catenin after it leaves the complex. It is equally possible that it binds beta-catenin while beta-catenin is still bound to Axin.

REACT_10017 (Reactome) Ubiquitinated beta-catenin is degraded by the proteasome.
REACT_10082 (Reactome) Beta-catenin is ubiquitinated by the SCF-B-TrCP1 complex.
REACT_10111 (Reactome) Beta-catenin associates with the destruction complex through an interaction with Axin and or APC. This association may also involve interactions with the 15 aa repeats in APC (Spink et al., 2001) or the third APC 20aa repeat and its N-terminal flanking residues (Ha et al., 2004, Xing et al., 2004; Liu et al., 2006).
REACT_10127 (Reactome) The phosphorylation of the 20 aa repeats in APC results in an increase in affinity for beta-catenin (Ha et al., 2004, Xing et al., 2004; Liu et al., 2006). The binding site of phospho -(20 aa) APC on beta-catenin overlaps the binding site of Axin on beta catenin. In addition, phosphorylated APC prevents the association of Axin with beta-catenin (Ha et al., 2004, Xing et al., 2004). In this model, phosphorylated APC may compete with Axin for beta-catenin binding, resulting in dissociation of the Axin:beta-catenin interaction in the destruction complex (see Kimelman and Xu 2006).
REACT_10134 (Reactome) The exact composition of the destruction complex is not known. A number of components appear to form a core complex, while others may associate with the complex transiently when a Wnt signal is present (reviewed in Kimelman and Xu, 2006). The core components include Axin, glycogen synthase kinase 3 (GSK-3), Casein kinase 1 (CKI) alpha, beta-catenin, Protein phosphatase 2A (PP2A) and Adenomatous Polyposis Coli (APC). CK1 epsilon, Diversin and PP1 may also be components of the complex.
REACT_9955 (Reactome) Following CKI-mediated phosphorylation at Ser45, beta-catenin is phosphorylated by GSK3 at Thr41.
REACT_9959 (Reactome) Phospho-(Ser45, Thr41) beta-catenin is phosphorylated by GSK3 at Ser37.
REACT_9977 (Reactome) B-TrCP associates with phosphorylated beta-catenin through the B-TrCP WD40 repeat region. Currently, it is unclear whether the ubiquitin ligase binds beta-catenin after it leaves the complex. It is equally possible that it binds beta-catenin while beta-catenin is still bound to Axin.
REACT_9978 (Reactome) CK1a binds to Axin and phosphorylates beta-catenin at Ser45 priming GSK3 mediated phosphorylation at the more N-terminal residues (Amit et al., 2002; Liu et al., 2002; Yanagawa et al., 2002).
REACT_9983 (Reactome) APC is phosphorylated on the 20 aa repeats by CK1 and potentially GSK-3. This significantly increases the binding affinity of the APC 20 aa repeats for beta-catenin, causing one of them to bind b-catenin in the same region as beta-catenin binds Axin, thus displacing beta-catenin from Axin ( Step 5 above) (Reviewed in Kimelman, 2006).
REACT_9987 (Reactome) Beta-catenin is then phosphorylated at Ser33. Phosphorylated S37 and S33 together with neighboring residues constitute the recognition motif for beta-TrCP.
