CollecTRI: Collection of Transcriptional Regulatory Interactions

Overview

The CollecTRI-derived regulons contain signed transcription factor (TF) - target gene interactions compiled from 12 different resources. This collection provides an increased coverage of transcription factors and was benchmarked against other known GRNs, showing a superior performance in identifying perturbed TFs based on gene expression data using the knockTF data sets.

Data availability

The CollecTRI regulons are available in the DoRothEA and decoupler packages through OmniPath. A tutorial on how to perform TF activity estimation using CollecTRI is available in R and python.

To load the CollecTRI regulons through R or python you can use the following lines:

# processed regulons
decoupleR::get_collectri(organism='human', split_complexes=FALSE)

# raw regulons
OmnipathR::collectri(organism=9606L, genesymbols=TRUE, loops=TRUE)

# processed regulons
import decoupler as dc
dc.get_collectri(organism='human', split_complexes=False)

# raw regulons
import omnipath as op
op.interactions.CollecTRI.get(genesymbols=True, organism=9606L, loops=True)
