Please also cite the original paper if you use a paticular descriptor in your research. The feature input of our model is the combination of one-hot encoding and the PSSM of a protein. Each sequence is transformed into a one-hot matrix with 100 rows and 20 columns and a PSSM matrix with 100 rows and 20 columns, which are integrated into a combination matrix with 200 rows and 20 columns as the feature input. "Python for Bioinformatics", which was translated and surpervised by Higuchi Chihiro, will be published.

Accordingly, PSSM-based feature descriptors have been successfully applied to improve 2005-02-19 · Background Detection of DNA-binding sites in proteins is of enormous interest for technologies targeting gene regulation and manipulation. We have previously shown that a residue and its sequence neighbor information can be used to predict DNA-binding candidates in a protein sequence. This sequence-based prediction method is applicable even if no sequence homology with a previously known DNA PSSM. From Bioinformatikpedia. Jump to: navigation.

Accordingly, PSSM-based feature descriptors have been successfully applied to improve the performance of various predictors of protein attributes. A bioinformatics toolkit for generating numerical sequence feature descriptors based on PSSM profiles. Evolutionary information in the form of a Position-Specific Scoring Matrix (PSSM) is a widely used and highly informative representation of protein sequences. Accordingly, PSSM-based feature descriptors have been successfully applied to improve the performance of various predictors of protein attributes. 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.

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.

Bioinformatics is the science that happens when computers are joined with the latest discoveries in genomics, biochemistry, and biophysics. It is a rapidly growing field that brings together elements of biology, chemistry, computer science, physics, and statistics. 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. using amino acid composition and PSSM profiles.
