Figure 5—figure supplement 2.

LY2090314-mediated WNT stimulation leads to increased ?-catenin stabilization in SMC1A mutant HCT116 cells. LY2090314-mediated WNT stimulation leads to increased β-catenin stabilization in SMC1A mutant HCT116 cells.

Unmodified HCT116 cells (WT), and cells modified to contain SMC1A mutations: SMC1A (1), c.2027A > G; SMC1A (2), c.2479 C > T, were treated with DMSO or LY2090314 at 100 nM for 24 hr. (A) Immunoblot of the membrane fraction of HCT116 wild type (WT) and SMC1A mutant-expressing HCT116 cells. The proteasome-targeted form of β-catenin phosphorylated at Ser33/37/Thr41 is slightly less abundant in the SMC1A mutants, and this phospho isoform is degraded in all cells following treatment with LY2090314. (B) Immunoblot of the cytoplasmic fraction shows increased basal level of phosphorylated β-catenin at Ser675 in the SMC1A mutant-expressing cells compared with HCT116 WT, and LY2090314 treatment markedly increased total β-catenin in the SMC1A mutants compared with HCT116 WT. Untrimmed blots and molecular size markers are available for A,B in Figure 5—source data 4.
