TRANSFAC Site Quality Scores
Quality scores, ranging from 1 to 6, reflect the
experimental reliability of a particular protein-DNA or miRNA-RNA
interaction. These scores and their meanings are described in the
table below.
Experimental Reliability of
Transcription Factor - Binding Site Interactions
or miRNA - Target Site Interactions
| Score | Meaning |
|---|---|
| 1 | Functionally confirmed transcription factor or miRNA binding site |
| 2 | Binding of pure protein or miRNA (purified or recombinant) |
| 3 | Immunologically characterized binding activity of a cellular extract |
| 4 | Binding activity characterized via a known binding sequence |
| 5 | Binding of uncharacterized extract protein to a bona fide element |
| 6 | No quality assigned |
