Use Chou’s 5-Step Rule to Classify Protein Modification Sites with Neural Network

الملخص EN

Lysine malonylation is a novel-type protein post-translational modification and plays essential roles in many biological activities.

Having a good knowledge of malonylation sites can provide guidance in many issues, including disease prevention and drug discovery and other related fields.

There are several experimental approaches to identify modification sites in the field of biology.

However, these methods seem to be expensive.

In this study, we proposed malNet, which employed neural network and utilized several novel and effective feature description methods.

It was pointed that ANN’s performance is better than other models.

Furthermore, we trained the classifiers according to an original crossvalidation method named Split to Equal validation (SEV).

The results achieved AUC value of 0.6684, accuracy of 54.93%, and MCC of 0.1045, which showed great improvement than before.
