SpectrAI-Initiative/protein_function_annotation

Protein Function Annotation Pipeline

Discipline: Proteomics | Tools Used: 4 | Servers: 2

Description

Annotate protein function: UniProt metadata, InterPro domains, functional prediction, and GO enrichment.

Tools Used

• query_uniprot from server-1 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory
• query_interpro from server-1 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory
• predict_protein_function from server-1 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory
• get_functional_enrichment from string-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/6/Origene-STRING

Workflow

1. Get UniProt metadata
2. Get InterPro domain annotations
3. Predict protein function
4. Run GO enrichment analysis

Test Case

Input

{
    "uniprot_id": "P04637"
}

Expected Steps

1. Get UniProt metadata
2. Get InterPro domain annotations
3. Predict protein function
4. Run GO enrichment analysis

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.
