Comprehensive Workflow for the Genome-wide Identification

Accordingly, PSSM-based feature descriptors have been commonly used as indispensable primary features to construct models, filling a major gap in the current bioinformatics research. For example, PSSM-based feature descriptors have successfully improved the prediction performance of structural and functional properties of proteins across a wide spectrum of bioinformatics applications (See Supplementary Table S1 in the Supplementary Material for a comprehensive lists of applications). – Profiles (PWM/PSWM, PSSM) are useful for less conserved motifs. Pattern matching with profiles gives a quantitative result (a score). You can improve your profiles with biological data.

If you read wiki carefully, you can see that PSSM is calculated in 3 steps. First frequency is calculated (how much times was the amino acid or nucleotide on that location in the motif), from that you can calculate probability (in the wiki example there were 10 sequences, so each freq. is divided by 10). Therefore, creating a precise model to predict the function of adaptor proteins is one of the vital tasks in bioinformatics and computational biology. Few computational biology studies have been conducted to predict the protein functions, and in most of those studies, position specific scoring matrix (PSSM) profiles had been used as the features to be fed into the neural networks.

We now have 2 ways to describe a motif! A PSSM-based neural network method for predicting DNA-binding sites in proteins has been developed. PSSMs were developed against different data sets and it was observed that significant computer time can be saved by replacing the reference data sets with much smaller reference data sets without loss of much prediction ability. This course will cover the basic concepts of structural bioinformatics and molecular modeling. A broad qualitative overview of macromolecular structure and protein folding will be provided which includes sequence alignment, secondary structure calculation, and tertiary structure prediction. If you read wiki carefully, you can see that PSSM is calculated in 3 steps.

This data set contains the Position Specific Scoring Matrix (PSSM) used as the LOGICOIL training set. This dataset was compiled from the CC+ coiled-coil database. This PSSM is used by LOGICOIL to predict the oligomeric state of coiled-coil sequences.
