BLAST-Like Alignment Tool. A DNA/protein sequence analysis program to find sequences of ≥ 95% sequence similarity of ≥ 40 bases or more in length. BLAT may miss more divergent or shorter sequence alignments. BLAT on proteins finds sequences of 80% and greater similarity of length 20 amino acids or more.
