A PSSM-FM ℳ of length L is a sequence of L PSSMs ℳ=M 1, M 2, …, M L where M i denotes the PSSM derived from A i, i∈[1, L]. The order ≪ of the PSSMs occurring in ℳ is imposed by the order of the corresponding alignment blocks.

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.

The work is an extension of our PSSM search tool PoSSuMsearch (Beckstette et al., 2006), so we briefly describe previous work on index-based PSSM matching and efficient p-value computation for PSSM matchscores (Sections 2.2 and 2.3) before describing the new concepts and algorithms used in the new version of PoSSuMsearch (Sections 2.4–2.6

This PSSM is used by LOGICOIL to predict the oligomeric state of coiled-coil sequences. More details … 2021-04-10 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.

Note that POSSUM is a generator of currently existed PSSM-based descritors If you read wiki carefully, you can see that PSSM is calculated in 3 steps.

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.
