Abstract: Depletion of FZR1 leads to BRAF stabilization and subsequent ERK activation. Supplementary Figure S2. Depletion of FZR1 triggers the onset of premature senescence in primary melanocytes. Supplementary Figure S3. APCFZR1 promotes BRAF ubiquitination and subsequent degradation in a D-box dependent manner. Supplementary Figure S4. FZR1 disrupts the BRAF dimerization process. Supplementary Figure S5. Phosphorylation of FZR1 N-terminus by ERK and CYCLIN D1/CDK4 inhibits the APCFZR1 E3 ubiquitin ligase activity. Supplementary Figure S6. Pharmacologically inhibiting BRAF/ERK and CDK4 restores the APCFZR1 E3 ligase activity. Supplementary Figure S7. Depletion of FZR1 co-operates with PTEN deficiency to promote co-activation of BRAF/ERK and AKT oncogenic signaling both in vitro and in vivo. Supplementary Table S1. Mutation and deletion of FZR1 and 14 APC core complex subunits identified in melanoma patients from the TCGA melanoma dataset (cbioportal.org).
