CyClus3D

CyClus3D identifies functional modules in integrated molecular interaction networks by clustering composite three-node network motifs using a 3D spectral clustering algorithm within Cytoscape.

Key Features:

• Cytoscape integration: Operates as a Cytoscape plugin to integrate and analyze molecular interaction networks.
• Three-Node Network Motif Clustering: Clusters composite three-node network motifs to capture functional relationships across distinct data types that conventional graph clustering can miss.
• 3D Spectral Clustering Algorithm: Applies a 3D spectral clustering algorithm to analyze spatial relationships in motif-derived network representations and detect dense topological structures.

Scientific Applications:

• Systems biology module detection: Identifies functional modules in integrated molecular networks to support systems-level interpretation of molecular interactions.
• Integrated multi-type interaction analysis: Reveals how distinct interaction types combine within networks by focusing on composite three-node motifs.
• Disease mechanism inference: Pinpoints motif-defined modules that can provide insights into the molecular mechanisms underlying complex biological processes and diseases.

Methodology:

Uses Cytoscape to integrate and analyze molecular interaction networks, focuses analysis on composite three-node motifs, and applies a 3D spectral clustering algorithm to detect dense topological structures.
