# Antibody-Target Analysis

**Discipline**: Immunology | **Tools Used**: 4 | **Servers**: 4

## Description

Analyze an antibody target: UniProt protein info, InterPro domains, protein properties, and biotherapeutic data from ChEMBL.

## Tools Used

- **`get_uniprotkb_entry_by_accession`** from `uniprot-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/10/Origene-UniProt`
- **`query_interpro`** from `server-1` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory`
- **`ComputeProtPara`** from `server-29` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio`
- **`get_biotherapeutic_by_name`** from `chembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL`

## Workflow

1. Get full UniProt entry
2. Get domain annotations
3. Compute protein parameters
4. Search ChEMBL biotherapeutics

## Test Case

### Input
```json
{
    "uniprot_accession": "P04637",
    "protein_sequence": "MEEPQSDPSVEPPLSQETFS"
}
```

### Expected Steps
1. Get full UniProt entry
2. Get domain annotations
3. Compute protein parameters
4. Search ChEMBL biotherapeutics

## 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](https://scphub.intern-ai.org.cn).
