Hi Vaibhav,

In order to obtain a list of tissue specific genes, please see this 
answer from a previous question (substitute rn4 where it says hg18):
https://lists.soe.ucsc.edu/pipermail/genome/2006-September/011685.html

We don't currently have a track with transcription factor binding sites 
for rn4. However, you may find the TFBS Conserved track on the hg18 
human assembly useful. This track contains some rat transcription factor 
data. The track description is here: 
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg19&g=tfbsConsSites.

You can obtain a list of the rat transcription factors that are in the 
TFBS conserved track along with their hg18 coordinates using the table 
browser (click "Tables" on the top blue menu bar). Select the Human Mar. 
2006 (NCBI36/hg18) and make the following selections:
group: Regulation
track: TFBS Conserved
table: tfbsConsSites
filter: click 'create'; under Linked Tables (bottom of page), select 
"hg18.tfbsConsFactors" & click "Allow filtering Using Fields in Checked 
Tables"; where you see 'species "does" match' delete the * and enter 
'rat' (without quotes); click submit.
output format: selected fields and related tables
output file: since there will be a lot of results,  enter the name you 
would like an output file to have
file type returned: plain text

Click "get output". Under Linked Tables, select 'hg18.tfbsConsFactors' 
and click "Allow filtering Using Fields in Checked Tables". select all 
the fields from both tables except 'bin' and click 'get output.'

If you want to convert these rat TFBS coordinates from hg18 to rn4, you 
can do most of the same directions as above, but set the 'output of 
format' to 'BED - browser extensible data' and enter a new file name. 
Then you can use the liftOver utility 
(http://genome.ucsc.edu/cgi-bin/hgLiftOver) to convert the hg18 
coordinates to rn4 coordinates. However, because file is so large, 
rather than using the web version you'll need to download the liftOver 
executable (http://hgdownload.cse.ucsc.edu/admin/exe/) and necessary 
chain file (hg18ToRn4.over.chain.gz from 
http://hgdownload.cse.ucsc.edu/goldenPath/hg18/liftOver/). For more 
information on using the liftOver executable, please see this previously 
answered Mailing list question: 
https://lists.soe.ucsc.edu/pipermail/genome/2008-August/016898.html

For a list of the rat transcription factors from the TFBS conserved site 
without hg18 coordinates, you can make the same selections in my 
original directions, but for table select tfbsConsFactors. Filter that 
table the same way I described above, and after clicking get output, 
select your fields interest and sumbit.

I hope this information is helpful. Please don't hesitate to contact the 
mail list again if you have any further questions.
