WebbProtein secondary structure prediction (PSSP) is an essential task in computational biology. To achieve the accurate. Matrix (PSSM) extraction. However, when only low-quality. PSSM can be obtained due to poor sequence homology, previous PSSP accuracy (merely around 65%) is far from practical usage for subsequent tasks. In this paper, we … WebbA PSSM is a matrix of log-odds ratios per position of a sequence motif. They are also referred to as profiles. They provide a means for computing the match odds for any new sequence. They are typically applied to finding transcription factor binding sites (TFBS) but also used to characterise protein domains.

Webb2.1 Introduction to Motifs. A biological motif, broadly speaking, is a pattern found occurring in a set of biological sequences, such as in DNA or protein sequences. A motif could be an exact sequence, such as TGACGTCA, or it could be a degenerate consensus sequence, allowing for ambiguous characters, such as R for A or G. Motifs can also be ...
