The Tumor Suppressor SCRIB is a Negative Modulator of the Wnt/β‐Catenin Signaling Pathway

SCRIB is a scaffold protein containing leucine‐rich repeats (LRR) and PSD‐95/Dlg‐A/ZO‐1 domains (PDZ) that localizes at the basolateral membranes of polarized epithelial cells. Deregulation of its expression or localization leads to epithelial defects and tumorigenesis in part as a consequence of its repressive role on several signaling pathways including AKT, ERK, and HIPPO. In the present work, a proteomic approach is used to characterize the...
