ClustalW2 (EBI)

ClustalW2 (EBI) performs global multiple sequence alignment of DNA and protein sequences to identify conserved regions for comparative genomics, phylogenetic analysis, and functional annotation.

Key Features:

• Global multiple sequence alignment: Performs global alignments of multiple DNA and protein sequences.
• C++ implementation: The alignment engine was completely rewritten in C++.
• Advanced alignment algorithms: Uses advanced alignment algorithms that were optimized in the C++ rewrite to improve accuracy and computational efficiency.
• Conserved-region detection: Identifies conserved regions across aligned sequences to support evolutionary and functional inference.

Scientific Applications:

• Comparative genomics: Detects conserved sequences across organisms to support comparative analyses.
• Phylogenetic analysis: Produces aligned sequences suitable for phylogenetic tree construction and evolutionary inference.
• Functional annotation: Enables identification of conserved motifs and regions for predicting structural or functional characteristics of genes and proteins.

Methodology:

Performs global multiple sequence alignment using advanced alignment algorithms optimized through a C++ rewrite to improve alignment accuracy and computational efficiency.
