NOTE: - when using rsa tools, the reference position depends on whether you are searching for upstream or downstream regions.
For upstream:
- position 0 is the first nucleotide of the start codon
For downstream:
- position 0 is the last nucleotide of the stop codon (last nucleotide in the ORF)
start codons - ATG stop codons - TAA, TAG or TGA
TRANSFAC database - transcription factor database where all all regulatory elements are between -1 & -800 relative to start codon.
