Title: | A neural network method for prediction of proteolytic cleavage sites in neuropeptide precursors | Authors: | LIU, Feng WETS, Geert |
Issue Date: | 2005 | Publisher: | Engineering in Medicine and Biology Society | Source: | 27TH ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE AND BIOLOGY SOCIETY: vol. 1-7. p. 2805-2808. | Series/Report: | PROCEEDINGS OF ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE AND BIOLOGY SOCIETY | Abstract: | Proteolytic processing occurs predominantly at basic amino acid residues. The existence of the cleavage sites not recognized by rules proposed in previous studies prompts us to test whether, and to what extent, the sites cleave. Due to the imbalanced cleavage site database from SWISS, Smote combined with Tomek links is applied to over-sample the data. A neural network method is then developed to predict the probabilities of proteolytic processing occurrences at the sites in neuropeptide precursors. The sensitivities are 91%, 93%, 91%, 90%, 79% and 83% for KR, RR, RK, KK, R and K, respectively, which is significantly better than previous prediction schemes. | Document URI: | http://hdl.handle.net/1942/4320 | ISBN: | 0-7803-8740-6 | DOI: | 10.1109/IEMBS.2005.1617056 | ISI #: | 000238998402158 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2007 |
