WebPTEN is a critical tumor suppressive phosphatase that is active in its dimer configuration at the plasma membrane. Polyubiquitination by the ubiquitin E3 ligase WWP1 (WW domain–containing ubiquitin E3 ligase 1) suppressed the dimerization, membrane recruitment, and function of PTEN. WebFeb 11, 2024 · Reactivated p73 is free to promote the expression of anti-tumorigenic genes, including CDKN1A ( p21) and BBC3 ( PUMA ), resulting in cell-cycle arrest and apoptosis. 14 Notably, we showed that tamoxifen increased ERβ-mutant p53 interaction, and p73-mutant p53 interaction was reciprocally decreased leading to the reactivation of p73 as a tumor …
