Overexpression of the glucose transporter GLUT4 in adipose cells interferes with insulin-stimulated translocation.

abstract：:Molecular dynamics simulations have been performed on the intrinsically disordered 39-residue N-terminal transactivation domain of p53 (p53(1-39)). Simulations not only revealed that p53(1-39) is natively compact, but also possesses a folded structure. Furthermore, leucine-rich hydrophobic clusters were found to play ...
