Neural Network Promoter Prediction

Read Abstract Help

PLEASE NOTE: This server runs the 1999 NNPP version 2.2 (March 1999) of the promoter predictor.

Enter a DNA sequence to find possible transcription promoters

Type of organism: prokaryote eukaryote
Include reverse strand? yes no
Minimum promoter score (between 0 and 1):

Cut and paste your sequence(s) here: Use single-letter nucleotides: (A, C, G, T).
You can include multiple sequences if each has a FASTA title line starting with >

Please be patient--promoter prediction takes about 10 seconds per kilobase.

Training set: Our training and test sets of human and Drosophila melanogaster promoter sequences are available to the community for testing transcription start site predictors. These sites also contain our representative, standardized data sets of human and Drosophila melanogaster genes.
