Low frequency damping of metal panels in ambient Air [PDF]

, 2008
Mathematical models of structural dynamics are widely used and applied in many branches of science and engineering and it has been argued that many of the shortfalls with these models are due to the fact that the physics of joint dynamics are not ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.
