    • Development of molecules with the ability to selectively inhibit particular protein-protein interactions is important in providing tools for understanding cell biology In this work, we describe efforts to select small Ras- and Raf-specific three-helix bundle affibody binding proteins capable of inhibiting the interaction between H-Ras and Raf-1, from a combinatorial library displayed on bacteriophage Target-specific variants with typically high nanomolar or low micromolar affinities (K-D) could be selected successfully against both proteins, as shown by dot blot, ELISA and real-time biospecific interaction analyses Affibody molecule variants selected against H-Ras were shown to bind epitopes overlapping each other at a site that differed from that at which H-Ras interacts with Raf-1 In contrast, an affibody molecule isolated during selection against Raf-1 was shown to effectively inhibit the interaction between H-Ras and Raf-1 in a dose-dependent manner Possible intracellular applications of the selected affibody molecules are discussed

  • Affibody-mediated retention of the epidermal growth factor receptor in the secretory compartments leads to inhibition of phosphorylation in the kinase domain
  • 2009

    • Abnormal activity of the epidermal growth factor receptor (EGFR) is associated with various cancer-related processes and motivates the search for strategies that can selectively block EGFR signalling. In this study, functional knockdown of EGFR was achieved through expression of an affibody construct, (Z(EGFR:1907))(2)-KDEL, with high affinity for EGFR and extended with the amino acids KDEL to make it resident in the secretory compartments. Expression of (Z(EGFR:1907))(2)-KDEL resulted in 80% reduction of the cell surface level of EGFR, and fluorescent staining for EGFR and the (Z(EGFR:1907))(2)-KDEL construct showed overlapping intracellular localisation. Immunocapture of EGFR from cell lysates showed that an intracellular complex between EGFR and the affibody construct had been formed, further indicating a specific interaction between the affibody construct and EGFR. Surface depletion of EGFR led to a dramatic decrease in the amount of kinase domain phosphorylated EGFR, coincident with a significant decrease in the proliferation rate.
