Sequence Logos: A New Way to Display Consensus Sequences

Sequence logo for 38 LexA binding sites on E.  coli DNA
covering the range from the 5' side at -10 to the 3' side
at 11.  The vertical scale is from 0 to 2 bits.  The logo
letters approximately follow a sine wave running from 1 to
2 bits with wavelength 10.6 bases because LexA binds into
two adjacent major grooves of the DNA.

Graph of citations to the logo and weblogo papers versus
time is exponentional from 1991 to 2015.
Citations to sequence logo papers per year.
blue: logo paper (from 1991 to present)
green: weblogo paper (from 2004 to present)
red: both papers (from 1991 to present, top curve)
The data are from the ISI Web of Science's Cited Reference Search. Total growth is exponential to at least 2010, but citations to the original logo paper leveled out starting in 2004 when Weblogo became available. The total may be leveling out by 2015.

Historical Note: We devised the title of this paper before we realized that a sequence logo is more than merely a way to display consensus sequences. Of course it is that, since one can read the strict consensus from the top letter at each position of the logo. But in addition one gets the frequencies and the total sequence conservation, so logos are more that just a display of consensus. It takes time to begin to think in a new way!
