First, we define two commonly used sequence conservation scoring methods: the entropy, and the parsimony score.
The row-and-column effect is caused by sites with a common pattern of conservation scoring high against each other – these sites are the ones that evolve more "accordingly" to the phylogenetic tree.
A similar performance was reached by Hu and Li [22] with a method based on support vector machines using features from position conservation scoring functions.
A FASTA file containing known mature metazoan miRNA sequences in miRBase was used as input to allow for conservation scoring.
The conservation scoring system relies on calculated "delta scores" – differences in estimated alignment scores between query and homologs, and query variants and homologs.
We refined the motif in the aligned C/EBP RDM sequence segments and then deployed a protocol involving keyword enrichment, native disorder prediction and conservation scoring in a survey of protein sequence databases.
Default commands were used in the miRDeep2 analysis except that conservation scoring was omitted and the parameter g was set to −1 to allow all precursors to be analyzed during automatic excision gearing.
A similar approach in combination with disorder prediction and conservation scoring, has shown that KEN-box destruction motifs are significantly enriched in the set of UniProt/Swiss-Prot entries annotated with cell-cycle keywords and Gene Ontology (GO) terms (Michael et al., 2008).
