01 · Input data
Three ways to provide proteins
Accessions
Enter multiple NCBI or UniProt protein accessions separated by commas or new lines. Fetch & preview is optional; Run Prediction can fetch them automatically.
Upload
Upload FASTA directly, or upload a TXT, CSV, or TSV accession list. Accession lists are fetched automatically.
Paste FASTA
Paste one or more amino-acid sequences. Every record must begin with a FASTA header using the > character.
Only amino-acid sequences are supported; nucleotide sequences should not be submitted.
02 · Model strategy
Choose speed or sensitivity
Fast
Uses dipeptide composition features. Best for larger protein sets and faster turnaround.
Sensitive
Uses tripeptide composition features. Best for smaller sets when prediction sensitivity is the priority.
03 · Prediction levels
A four-level hierarchy
Single vs dual
Determines whether a protein has one predicted localization or a dual localization.
Single localization
Classifies single-localized proteins into 10 cellular compartments.
Dual localization
Classifies dual-localized proteins into 6 supported compartment pairs.
Membrane topology
Classifies predicted membrane proteins as single-pass or multi-pass.
04 · Run analysis
One primary action
Select the required levels and model, then choose Run Prediction. Processing status remains on the Prediction page; when the job finishes, the browser moves directly to Results. Email notification is optional.
05 · Read results
Save and navigate results
Copy the private results link when the job is submitted; it can reopen and monitor the job, and remains valid for 30 days. Completed outputs are organized from Level I through Level IV above a full-width, horizontally scrollable table. Download one level or export all available levels together.
