Abstract Functional characterization of a protein sequence is one the most frequent problems in biology. This task usually facilitated by accurate three‐dimensional (3‐D) structure studied protein. In absence an experimentally determined structure, comparative or homology modeling can sometimes provide useful 3‐D model for that related to at least known structure. Comparative predicts given (target) based primarily on its alignment more proteins (templates). The prediction process consists...

The NCBI dbSNP database lists over 9 million single nucleotide polymorphisms (SNPs) in the human genome, but currently contains limited annotation information. SNPs that result amino acid residue changes (nsSNPs) are of critical importance variation between individuals, including disease and drug sensitivity.We have developed LS-SNP, a genomic scale software pipeline to annotate nsSNPs. LS-SNP comprehensively maps nsSNPs onto protein sequences, functional pathways comparative structure...
