## TL;DR

A new model called GOMER predicts how transcription factors bind to DNA, considering interactions between them.

## Contribution

GOMER introduces a physically principled approach to model transcription factor binding with cooperativity and competition.

## Key findings

- GOMER calculates binding probabilities using position weight matrices.
- The model incorporates effects of cooperativity and competition through equilibrium calculations.

## Abstract

A computational model, GOMER, is presented that predicts transcription-factor binding and incorporates effects of cooperativity and competition.

We have developed a computational model that predicts the probability of transcription factor binding to any site in the genome. GOMER (generalizable occupancy model of expression regulation) calculates binding probabilities on the basis of position weight matrices, and incorporates the effects of cooperativity and competition by explicit calculation of coupled binding equilibria. GOMER can be used to test hypotheses regarding gene regulation that build upon this physically principled prediction of protein-DNA binding.
