Functional analysis of novel β-catenin mutants

Creator:: Al-Fageeh, Mohamed B.
Abstract:: β-catenin is a multi functional protein that is involved in cell-cell adhesion and cell signaling. In non-stimulated cells, β-catenin is tightly down-regulated by GSK-3β-dependent phosphorylation at Ser and Thr residues, followed by rapid ubiquitination and proteasomal degradation. It is well established that mutations within the regulatory GSK-3β region lead to...
