Abstract Prediction of nuclear proteins is one of the major challenges in genome annotation. A method, NcPred is described, for predicting nuclear proteins with higher accuracy exploiting n-mer statistics with different classification algorithms namely Alternating Decision (AD) Tree, Best First (BF) Tree, Random Tree and Adaptive (Ada) Boost. On BaCello dataset [1], NcPred improves about 20% accuracy with Random Tree and about 10% sensitivity with Ada Boost for Animal proteins compared to existing techniques. It also increases the accuracy of Fungal protein prediction by 20% and recall by 4% with AD Tree. In case of Human protein, the accuracy is improved by about 25% and sensitivity about 10% with BF Tree. Performance analysis of NcPred clearly demonstrates its suitability over the contemporary in-silico nuclear protein classification research.

1 Introduction
Nucleus, popularly known as the control center of a cell, is the central unit of eukaryotic cells [2]. Unlike other organelles, its function is regulated by two genomes due to the presence of an explicit nuclear genome. It performs a plethora of biochemical reactions like oxidative phosphorylation, Krebs cycle, DNA replication, transcription, translation, etc. In addition nuclei are also involved in apoptosis and ionic homeostasis [3]. Because of their multidimensional utility, nuclear proteins are associated with several diseases, including Xeroderma pigmentosum, Fanconis anaemia, Bloom syndrome, Ataxia telangiectasia and Retinoblastoma [4] etc.
