Motif Detection in Protein Sequences

Designing Of Degenerate Primers-Based Polymerase Chain Reaction (PCR) For Amplification Of WD40 Repeat-Containing Proteins Using Local Allignment Search Method

Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...

Expression Analysis of RNA-Binding Motif Gene on Y Chromosome (RBMY) Protein Isoforms in Testis Tissue and a Testicular Germ Cell Cancer-Derived Cell Line (NT2)

a key factor in spermatogenesis and disorders associated with this protein have been recognized to be related to male infertility. Although it was suggested that this protein could have different functions during germ cell development, no studies have been conducted to uncover the mechanism of this potential function yet. Here, we analyzed the expression pattern of RBMY protein isoforms in test...

Development of an Efficient Hybrid Method for Motif Discovery in DNA Sequences

This work presents a hybrid method for motif discovery in DNA sequences. The proposed method called SPSO-Lk, borrows the concept of Chebyshev polynomials and uses the stochastic local search to improve the performance of the basic PSO algorithm as a motif finder. The Chebyshev polynomial concept encourages us to use a linear combination of previously discovered velocities beyond that proposed b...

A Comparative Analysis of Computational Motif-Detection Methods

The detection of motifs within and among families of protein sequences can provide useful information regarding the function, structure and evolution of a protein. With the increasing number of computer programs available for motif detection, a comparative evaluation of the programs from a biological perspective is warranted. This study uses a set of 20 reverse transcriptase (RT) protein sequen...

CpG Motif as an Adjuvant in Immunization of a Recombinant Plasmid Encoding Hepatitis C Virus Core Protein

Mining Protein Sequences for Motifs

We use methods from Data Mining and Knowledge Discovery to design an algorithm for detecting motifs in protein sequences. The algorithm assumes that a motif is constituted by the presence of a "good" combination of residues in appropriate locations of the motif. The algorithm attempts to compile such good combinations into a "pattern dictionary" by processing an aligned training set of protein ...
