## What it does

This skill queries the Human Protein Atlas through a Python wrapper script. While RNA-seq data tracks transcription, this tool confirms actual protein presence. The database measures abundance via immunohistochemistry. Staining levels range from Not Detected to High.

The commands require the `uv` tool on your PATH. It runs subcommands like `get-tissue-expression` through `scripts/hpa_cli.py`. The script manages rate limits and retries failed calls automatically. Output goes straight to disk. Files must be saved in `/tmp/` because payload sizes crash normal terminal streams.

HPA strictly targets wild-type human proteins. Any query for non-human species or QTL variant associations will fail immediately. You must also record user license consent under `.licenses/human_protein_atlas_database_LICENSE.txt` on the initial run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill human-protein-atlas-database -a claude-code
```
```bash
npx skills add google-deepmind/science-skills --skill human_protein_atlas_database -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/human_protein_atlas_database/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/human_protein_atlas_database/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill human_protein_atlas_database -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/human_protein_atlas_database/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill human_protein_atlas_database -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/human_protein_atlas_database/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

## When to use it
- map gene symbols to Ensembl IDs for queries
- retrieve protein expression levels in normal human tissues and cancer types
- identify subcellular protein localization across organelles
- compare RNA-seq consensus levels against observed protein abundance
- filter genes based on tissue-specific protein criteria

## Example prompts
- Resolve the Ensembl ID for TP53 and save output to /tmp/tp53.json
- Get tissue protein expression for ENSG00000130234 in the thyroid gland
- Search HPA for genes with elevated expression in the amygdala

# Human Protein Atlas (HPA) Database Integration

This skill provides semi-quantitative protein expression and spatial
localisation data from the Human Protein Atlas (HPA). While RNA-seq (e.g., GTEx)
tells us if a gene is being transcribed, HPA confirms if the protein product
actually exists, where it is located within the cell (e.g. nucleus vs
cytoplasm), and its concentration in systemic blood circulation. The data is
based on Immunohistochemistry (IHC) across normal human tissues and cancer
types.

## Prerequisites

1.  **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
    `uv` is installed and on PATH.
2.  **User Notification**: If .licenses/human_protein_atlas_database_LICENSE.txt
    does not already exist in the workspace root directory then (1) prominently
    notify the user to check the terms at
    https://www.proteinatlas.org/about/licence, then (2) create the file
    recording the notification text and timestamp.

## When to Use

**Use this skill when you need to:**

-   Map a gene symbol to its Ensembl ID for HPA queries.
-   Retrieve the semi-quantitative protein abundance in normal human tissues and
    cancer types based on IHC staining (High, Medium, Low, or Not Detected).
-   Find the specific organelles or subcellular structures where a protein has
    been localized (e.g., nucleoplasm, mitochondria).
-   Check the consistency/agreement between RNA-seq consensus and protein
    expression levels.
-   Search for genes based on specific protein expression criteria (e.g.,
    "elevated in amygdala" or "secreted proteins").

**Do NOT use when you need to:**

-   Query eQTLs, pQTLs, or any variant-level associations. HPA provides
    wild-type expression data and knows nothing about QTLs.
-   Query gene expression in non-human species. HPA is strictly for human
    proteins.
-   Retrieve purely quantitative RNA expression without interest in the protein
    product (consider using the GTEx skill instead).

## Command Selection Guide

**Pick the right command on the first try.** Match the user's input to the
correct subcommand below.

-   Map a gene symbol to Ensembl ID: `resolve-ensembl-id`
