Protein Interaction Network Analysis

Discipline: Systems Biology | Tools Used: 4 | Servers: 2

Description

Build protein interaction network: map identifiers with STRING, get PPI network, compute enrichment, and link to KEGG pathways.

Tools Used

• mapping_identifiers from string-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/6/Origene-STRING
• get_string_network_interaction from string-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/6/Origene-STRING
• get_ppi_enrichment from string-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/6/Origene-STRING
• kegg_link from kegg-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/5/Origene-KEGG

Workflow

1. Map gene names to STRING IDs
2. Get interaction network
3. Compute PPI enrichment
4. Link to KEGG pathways

Test Case

Input

{
    "genes": [
        "TP53",
        "BRCA1",
        "MDM2"
    ],
    "species": 9606
}

Expected Steps

1. Map gene names to STRING IDs
2. Get interaction network
3. Compute PPI enrichment
4. Link to KEGG pathways

Usage Example

Note: Replace sk-b04409a1-b32b-4511-9aeb-22980abdc05c with your own SCP Hub API Key. You can obtain one from the SCP Platform.
