identification of miRNA for zebrafish genes

Question

[rajasekargutha]

how to identify predicted miRNAs for target genes from zebrafish. is there any online databases for this?

[biofalconch]

I don't understand, do you want to find novel miRNAs, conserved miRNAs or predict their targets? To identify novel miRNAs, you might want to look at miRDeep2. To find conserved miRNAs, you will be better off by aligning your sequences against miRBase And last but not least, there is already target predictions for zebrafish, in TargetScanFish

Hope it helps :)

We were trying to get OP to do some work :)

While everyone wants to be super helpful on Biostars we are trying to get new Biostars users to think/do some research themselves instead of handing them ready information/search results.

Did you look for any resources on google? Please try this: http://bfy.tw/8V5o

If there is something I have missed, please clarify the question.

i have searched but i didnt get

Unless your search works in a different dimension than we are in the very first hit I saw was for the thing you are asking about. TargetScanFish.

To identify predicted target genes of zebrafish miRNAs, have a look here http://www.targetscan.org/fish_62/

If you want to correlate the expression of miRNA promoters and predicted target genes (the ones you get from above data), you can use zebrafish CAGE-seq datasets to see how miRNA/target genes correlate across developmental stages.

Have a look here http://nar.oxfordjournals.org/content/early/2015/12/15/nar.gkv1354.full Annotation of Zebrafish pri-miRNAs promoters and CAGE-seq detected active Drosha processing events.

You also have access to histone modifications and RNA-seq data from same stages. You can visualize data from UCSC custom track here: http://genome-euro.ucsc.edu/cgi-bin/hgHubConnect?hgsid=218695066_W0Xr4VlL7iBMcdhAvDjYAfPTS5Na
