Protein and peptide design
With Resonant Recognition Model frequency and phase identified for particular function/interaction we can:
-
analyse protein biological function;
-
predict key amino acids (“hot spots mutations”) for the particular function;
-
design de novo peptides with the desired biological function or interaction ability;
This approach has been already proved in number of examples including:
​
We have designed de-novo peptide that can inhibit beta-lactamase in resistant bacteria.
​
In the case of Fibroblast Growth Factors (FGF), two RRM characteristic frequencies were identified: one related to receptor recognition and another related to “growth activity”. The aim of that particular project was to design peptide which can competitively bind to the FGF receptor but without inducing growth. Using only receptor recognition frequency the 16-mer peptide was designed, experimentally tested and indeed had receptor recognition activity without inducing growth.
​
In the case of HIV virus, the one common RRM frequency was identified for all HIV envelope protein despite their high variability. This frequency was used to design peptide that can immunologically mimic all HIV isolates and thus could be a good candidate for vaccine.
​
In the case of interleukin-12, which can significantly affect tumour progression, the RRM model was used to design de-novo interleukin-12 like peptide. This peptide has been synthetised and tested experimentally on cancer cell line affecting cancer cell growth and survival causing apoptosis.
​
Similar idea was used to mimic myxoma virus oncolytic function. Myxoma virus (MV) is rabbit-specific poxvirus pathogen that also exhibits unique tropism for human tumor cells and is dramatically oncolytic for human cancer xenografts. The RRM characteristic frequency for MV proteins was identified and used to design peptides that were experimentally shown to mimic myxoma virus oncolytic function.
