A program for detecting similar nucleotide sequences by comparing queries to reference databases with known function or taxonomy, commonly used in bioinformatics.
TetraBlaster is a bioinformatics application used to perform sequence similarity searches to identify homologous sequences. It utilizes a heuristic algorithm to rapidly compare a query nucleotide or protein sequence against reference sequence databases such nucleotide (nt/nr), expressed sequence tags (EST), sequence tagged sites (STS), genomic survey sequences (GSS), high-throughput genomic sequences (HTGS), protein data bank (PDB), SwissProt, PIR, PRF, and custom user databases.
Key features of TetraBlaster include:
By rapidly scanning sequence databases for local alignments, TetraBlaster enables discoveries of sequence motifs, gene families, and functional domains shared between novel and previously characterized genes. It is a useful tool for functional inference, phylogenetic classification, and genomic annotation projects.
