Identifying transcription factors for a list of genes

Is there a way to find transcription factors for mouse genes if Ensemble IDs are known?

In an article I'm trying to recreate, transcription factor features were retrieved from GTRD database, which is no longer in service. Here is the study and corresponding citation:

"For transcription factors, we mapped the Gene Transcription Regulatory Database (v18_06)14 to ±200 nucleotides to transcriptional start sites supplied by BioMart for the human reference genome build GRCh38.p12 and the mouse reference genome build GrCm38.p6."

Unfortunately, I wasn't able to find a substitute for GTRD. Any suggestions?

*I have found a list of all known TF for mice in AnimalTFGB V4.0, but no luck how to link them to my list of Ensemble gene IDs

Are you sure? I see it here.

Yep, it doesn't really work in Ukraine. I tried VPN and it didn't work out

It also doesn't load for me so you're not going crazy

Funnily enough, I had to do something similar recently. After a good amount of backgrond research, it turns out that this is the best/well-cited resource for this.

Let me know what you think!

AnimalTFDB 4.0

Thank you very much for the response! I've came across this resource as well? but the only thing I've found is the list of TFs for mice. Is there a way to "connect" TFs to the genes They regulate?

My final goal is a matrix with genes as rows and TFs as columns, with 1 and 0 describing the interaction

  • 1 - TF regulates the expression of the gene
  • 0 - TF does not interact with a gene
gene Ensemble ID / TF Symbol  Tbx2  Dmtf1  Irx4  Irf3 
ENSMUSG00000000001            1     0      1     1
ENSMUSG00000000003            0     0      0     0
ENSMUSG00000000028            0     1      0     0
ENSMUSG00000000031            0     1      0     0
ENSMUSG00000000037            0     0      0     1

Funnily enough, I was also trying to do this. It seems like you want what I also recently needed.

A mouse-specific all-known-TFs to their targets network.

JASPAR was the only place where I found genome-wide scans for TONS of different TFs.

HOCOMOCO v11 is also another great resource but the problem as compared to JASPAR is that there's a tradeoff. HOCOMOCO is experimental evidence which is biased depending on the tissue as opposed to straight up scanning the entire DNA of the genome.

You can use an R package called dorothea to access gene regulatory transcription factors. It contains a comprehensive resources of curated collection of TFs and their target genes.

library(dorothea)
library(OmnipathR)
library(decoupleR)

#it is available for only human and mouse
net <- decoupleR::get_dorothea(levels = c('A', 'B', 'C', 'D'), organism = "human")
[2023-08-29 09:44:20] [SUCCESS] [OmnipathR] Loaded 278830 interactions from cache.
