Abbreviations: MW=molecular weight; rBA=relative binding affinity.
The given numbers indicate the position of the peptide in the amino acid sequence of SOX2.
Number of amino acids.
The relative binding affinities were determined by comparing the inhibition of the reporter peptide binding by the analysed peptides in relation to the inhibition obtained with a positive control peptide, which was set as 100%. The positive control peptide was YLLPAIVHI from RNA helicase p72 and the reporter peptide was ILK(FITC)EPVHGV from HIV-1 reverse transcriptase. All peptides were used at a concentration of 10 μM.
