IN-MACA-MCC : Integrated Multiple Attractor Cellular Automata with Modified Clonal Classifier for Human Protein Coding and Promoter Prediction

Abstract EN

Protein coding and promoter region predictions are very important challenges of bioinformatics (Attwood and Teresa, 2000).

The identification of these regions plays a crucial role in understanding the genes.

Many novel computational and mathematical methods are introduced as well as existing methods that are getting refined for predicting both of the regions separately; still there is a scope for improvement.

We propose a classifier that is built with MACA (multiple attractor cellular automata) and MCC (modified clonal classifier) to predict both regions with a single classifier.

The proposed classifier is trained and tested with Fickett and Tung (1992) datasets for protein coding region prediction for DNA sequences of lengths 54, 108, and 162.

This classifier is trained and tested with MMCRI datasets for protein coding region prediction for DNA sequences of lengths 252 and 354.

The proposed classifier is trained and tested with promoter sequences from DBTSS (Yamashita et al., 2006) dataset and nonpromoters from EID (Saxonov et al., 2000) and UTRdb (Pesole et al., 2002) datasets.

The proposed model can predict both regions with an average accuracy of 90.5% for promoter and 89.6% for protein coding region predictions.

The specificity and sensitivity values of promoter and protein coding region predictions are 0.89 and 0.92, respectively.
