Synthesis pass · prose summary of the discoveries below

AXIN1 is a multi-domain scaffold protein that serves as the concentration-limiting core of the β-catenin destruction complex, coordinating the phosphorylation, ubiquitination, and proteasomal degradation of β-catenin to suppress canonical Wnt signaling (PMID:22682247, PMID:10700176). Its central intrinsically disordered region positions GSK3β, CK1ε, APC, β-TrCP, and PP2A on the same platform, with acetylation at K147 regulating β-TrCP recruitment and lactylation at the same residue promoting AXIN1 degradation under hypoxia (PMID:21087614, PMID:35707358, PMID:38972426). Beyond Wnt suppression, AXIN1 scaffolds a GSK3β/Pin1/PP2A complex that destabilizes c-Myc, interacts with NRF2 to restrain antioxidant gene expression, binds YAP/TAZ to control Hippo pathway output, and recruits USP35 to stabilize IRF3 for type I interferon production through TBK1-triggered phase separation (PMID:19131971, PMID:25336178, PMID:35921500, PMID:39384753). Loss-of-function mutations in AXIN1 are recurrently found in hepatocellular carcinoma, where conditional deletion cooperates with c-Met to drive β-catenin- and YAP/TAZ-dependent tumorigenesis (PMID:10700176, PMID:30737831, PMID:35921500).
