freqAnalysis – Identify Statistically Aberrant k-length Nucleotide Motifs in coding DNA sequences

freqAnalysis

:: DESCRIPTION

freqAnalysis was designed to identify statistically aberrant k-length nucleotide motifs in coding DNA sequences, specifically to identify putative programmed translational frameshift sites. These are short sequences capable of inducing highly efficient ribosomal frameshifting by destabilizing normal ribosome-mRNA interaction. Because of the potentially catastrophic effect of frameshifting on normal protein production, we reasoned, such sites would be selected against by evolution and hence statistically underrepresented in protein-encoding sequences.
