There have been several computational methods proposed in the literature to deal with the DNA-binding protein identification. However The experiment results demonstrate that PSSM Distance Transformation is an available protein sequence encoding method and SVM-PSSM-DT is a useful tool for identifying the DNA-binding proteins. A user-friendly web-server of SVM-PSSM-DT was constructed, which is freely accessible to the public at the … Identification of proteins secreted by malaria parasite into erythrocyte using SVM and PSSM profiles BMC Bioinformatics . 2008 Apr 16;9:201. doi: 10.1186/1471-2105-9-201.

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. Bioinformatics Stack Exchange is a question and answer site for researchers, developers, students, teachers, and end users interested in bioinformatics.

DBS-PSSM och DBS-Pred förutsäger DNA-bindningen i ett protein från deras BMC Bioinformatics , 2006, 7: 262; ^ Tjong, H. och Zhou, H.-X. DISPLAR: en  A position weight matrix, also known as a position-specific weight matrix or position-specific scoring matrix, is a commonly used representation of motifs in biological sequences. PWMs are often derived from a set of aligned sequences that are thought to be functionally related and have become an important part of many software tools for computational motif discovery. A Position-Specific Scoring Matrix ( PSSM) is a "profile that gives the log-odds score for finding a particular matching amino acid in a target sequence". A PSSM, or Position-Specific Scoring Matrix, is a type of scoring matrix used in protein BLAST searches in which amino acid substitution scores are given separately for each position in a protein multiple sequence alignment. Thus, a Tyr-Trp substitution at position A of an alignment may receive a very different score than the same substitution at position B. The PSSM gives us a tool to score how close any sequence is to the collected sequences used to create the scoring matrix (also called the training sequences).

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. More details on the training set can be found in the reference below. 2015-02-06 · Background DNA-binding proteins play a pivotal role in various intra- and extra-cellular activities ranging from DNA replication to gene expression control.
