RUNX3
From Wikipedia, the free encyclopedia
Runt-related transcription factor 3 is a protein that in humans is encoded by the RUNX3 gene.[1]
This gene encodes a member of the runt domain-containing family of transcription factors. A heterodimer of this protein and a beta subunit forms a complex that binds to the core DNA sequence 5'-YGYGGT-3' found in a number of enhancers and promoters,[2] and can either activate or suppress transcription. It also interacts with other transcription factors. It functions as a tumor suppressor, and the gene is frequently deleted or transcriptionally silenced in cancer. Multiple transcript variants encoding different isoforms have been found for this gene.[3]
In melanocytic cells RUNX3 gene expression may be regulated by MITF.[4]
Knockout mouse
Runx3 null mouse gastric mucosa exhibits hyperplasia due to stimulated proliferation and suppressed apoptosis in epithelial cells, and the cells are resistant to TGF-beta stimulation.[5]
Interactions
RUNX3 has been shown to interact with TLE1.[6]
