XlinkCyNET

XlinkCyNET visualizes residue-to-residue protein cross-links derived from chemical cross-linking coupled with mass spectrometry (XL-MS) within Cytoscape to support analysis of protein interaction networks.

Key Features:

• Cytoscape integration: Implements a Java plugin integration with Cytoscape to represent XL-MS-derived protein interactions within Cytoscape networks.
• XL-MS data processing: Processes chemical cross-linking coupled with mass spectrometry (XL-MS) data to extract residue-to-residue cross-link connections.
• Rectangular-bar cross-link visualization: Renders intra- and interprotein cross-links using a rectangular-bar style that represents cross-linked residue positions on protein sequences.
• 3D structural mapping: Maps and visualizes cross-links onto three-dimensional protein structures to relate cross-link positions to spatial arrangements.
• Scalability: Supports large-scale networks, managing datasets containing thousands of proteins and cross-links.

Scientific Applications:

• Structural Biology: Investigates spatial organization and interaction dynamics of proteins at residue-level resolution using XL-MS constraints.
• Proteomics: Integrates cross-linking data into proteomic network analyses to elucidate protein interactions and complex topology.
• Drug Discovery: Supports identification of interaction interfaces and potential targets by providing residue-level interaction maps.

Methodology:

XlinkCyNET processes XL-MS data to generate residue-to-residue connections within protein networks.
