A variety of parameters were considered in the selection of putative P-sites.
Confirmed P-Sites have lower Hydrophobicity Scores. The P-site Similarity Score
is lower the more that it resembles typical confirmed corresponding P-Ser, P-Thr
or P-Tyr sites. The Maximum KInase Score provides the calculated score for
highest match of 500 human protein kinases for the amino acid sequence
surrounding the target P-site as determined with Kinase Substrate Predictor V2.
The Sum KInase Score provides the additive sum of the positive individual Kinase
Substrate Predictor V2 scores from 500 human protein kinases. The Conservation
Score is the average of the percent similarity of the human P-site with the
equivalent P-site in 20 other diverse species. Click the coloured buttons below
