Finding Ultraconserved elements between human and zebrafish

Hi all,

I am looking to find ultraconserved elements between human and zebrafish. I understand multiple genomes (including these species) have already been aligned and ultraconserved elements have been identified. For example Miller et al. 2007.

Is there a website where I can download a list of ultraconserved elements found in two species? Ideally with some additional information such as genomic location and percentage identity.

Thanks in advance.

You can download/browse the conserved elements between human/zebrafish from ANCORA browser maintained by Lenhard's group. http://ancora.genereg.net/

You can select multiple CNEs based on similarity of 100%, 90%, 80% and so on.

Thanks for the suggestion. I have a follow-up question. Do you know how to download all conserved elements as a single table at once? So far, I can only select specific elements from the browser and download them individually.

Not sure, try with wget. Or contact the authors.

Files are available for download at Ancora. See an example folder: http://ancora.genereg.net/downloads/danRer10/vs_human/

HCNE location files are named

HCNE_asm1_asm2_Xpc_Ycol.bed.gz

where asm1 and asm2 are identifiers for the compared genome assemblies, X is the percent identity threshold used for HCNE detection and Y is the number of alignment columns (window size) over which percent identity is computed
