RUNX3, also known as runt-related transcription factor 3, belongs to the RUNX family that regulate the expression of genes involved in cellular differentiation and cell cycle progression. A heterodimer of this protein and a beta subunit forms a complex that binds to the core DNA sequence 5-PYGPYGGT-3 found in a number of enhancers and promoters, and can either activate or suppress transcription. It also interacts with other transcription factors. It is a strong candidate as a gastric cancer tumor suppressor.
