Translate gene & protein identifiers across databases

Map identifiers between CARD, NCBI Protein, Nucleotide and Gene, UniProt and KEGG, and explore NCBI identical proteins and UniProt similar gene clusters, all in one place.

Tools

Three tools, one place

Pick the one that fits your question. Each accepts one or many identifiers, or a CSV file.

Identifier mapper

Translate identifiers from one database to another.

6 databases, any direction
Exhaustive and detailed mapping
Through similar genes or identical proteins

Open mapper

Identical proteins

Retrieve the NCBI Identical Protein Group of a protein.

One or many NCBI identifiers
As an ID list or a detailed table
Download as JSON or CSV

Find identical proteins

Similar genes

Fetch UniProt clusters of genes that share a given identity.

100%, 90% or 50% identity clusters
Optionally include cluster names
Batch queries with CSV files

Find similar genes

How it works

From identifier to answer in three steps

Choose your databases

Select where your identifiers come from and where you want to translate them.

Add your identifiers

Type or paste them separated by commas, click an example, or drop a CSV file.

Explore and export

Each identifier gets its own result card. Copy IDs, open them in the source database or download everything.

Supported databases

Six major biological databases

Identifiers are retrieved live from the public services, so results stay up to date.

CARD

Comprehensive Antibiotic Resistance Database.

ARO:3002535

NCBI Protein

Protein sequence records from GenBank, RefSeq and more.

WP_010896559.1

NCBI Nucleotide

Nucleotide sequence records from GenBank and RefSeq.

AY536519

NCBI Gene

Gene-centred information across many organisms.

76524190

UniProt

UniProtKB protein knowledgebase and UniRef clusters.

G0L217

KEGG

KEGG GENES entries linked to pathways and organisms.

Open source

Built on ginmappeR

Gintegrator is built upon the ginmappeR R package, available at the Bioconductor repository, which provides the core identifier translation functionality. You can also run Gintegrator locally or with Docker: see the Gintegrator repository on GitHub.
