"Recent studies show that DUBs play essential roles in proliferation, motility, and chemoresistance of malignant cells through stabilizing critical proteins.5 For example, USP49 deubiquitinates FKBP51, which serves as a scaffold for dephosphorylating Ser473 residue at Akt, and further sensitizes pancreatic cancer cells to gemcitabine."
"Mechanistically, <span class="match term0">USP49</span> deubiquitinates and stabilizes <span class="match term1">FKBP51</span>, which in turn enhances PHLPP's capability to dephosphorylate AKT Furthermore, <span class="match term0">USP49</span> inhibited pancreatic cancer cell proliferation and enhanced cellular response to gemcitabine in a <span class="match term1">FKBP51</span>-AKT-dependent manner."
