Thanks for using the UCSC Genome Browser and for inquiring about the table location for CTCF binding sites.
Here is a related
previously answered mailing list question.
From the
description page for tfbsConsSites, u
nder the methods section:
The Transfac Matrix Database (v.7.0) contains position-weight matrices for 398 transcription factor binding sites, as characterized through experimental results in the scientific literature. Only binding matrices for known transcription factors in human, mouse, or rat were used for this track (258 of the 398).If a factor isn't in our list of 258, it did not meet our criteria
for inclusion in th
e
tfbsConsSites table
.
Under the credits section, you can see that "these data were generated using the Transfac Matrix and Factor databases created by Biobase."
You can search for any of the 398 full data set of factors on the Transfac site from
BiobaseSearching
the
Transfac
database
for "factor name" does yield 4 results, including
the result for human.
For future reference, t
here are many other UCSC Genome Browser tables that reference CTCF, for example:
Transcription Factor ChIP-seq track This track shows CTCF binding sites from a large collection of ChIP-seq experiments.
In the table wgEncodeRegTfbsClusteredV3, you can filter for "CTCF" in the "name" column.
You can also go to the
hg19 browser
and click on the "track search" button to search for "CTCF."
