Towards "bionic" proteins: Replacement of continuous sequences from HIF-1α with proteomimetics to create functional p300 binding HIF-1α mimics

Abstract

Using the HIF-1α transcription factor as a model, this manuscript illustrates how an extended sequence of α-amino acids in a polypeptide can be replaced with a non-natural topographical mimic of an α-helix comprised from an aromatic oligoamide. The resultant hybrid is capable of reproducing the molecular recognition profile of the p300 binding sequence of HIF-1α from which it is derived.
