Mdm2 arrestin ip6
Indeed, we have shown that the β-arr2-dependent titration of the oncoprotein Mdm2 out of the nucleus and the subsequent enhancement of p53 activity, were inhibited when self-assembly of β-arr2 was prevented by mutation of the binding sites for IP6, a sugar reported to stabilize the association between the N-terminal and C-terminal globular ...
