RUNX3 also known as Runt-related transcription factor 3 is a protein that plays an important role in regulating gene expression. The protein has a mass of approximately 44 kDa. RUNX3 is found mainly in tissues like the gastrointestinal tract and neural systems. It functions as a DNA-binding transcription factor that regulates various genes responsible for important cellular processes.
Biological function summary

The function of RUNX3 involves the regulation of cell proliferation differentiation and apoptosis. RUNX3 often forms a complex with the core-binding factor beta (CBFβ) enhancing its stability and DNA-binding capability. This protein is essential in maintaining cellular homeostasis and influencing the immune response particularly through its role in T cell development.

Pathways

RUNX3 is heavily involved in the TGF-beta signaling pathway and the Wnt signaling pathway. It interacts with several proteins such as SMADs in the TGF-beta pathway to modulate gene expression that affects cell growth and survival. Interaction with beta-catenin in the Wnt signaling pathway further emphasizes its importance in regulating cell fate decisions.

Alterations in RUNX3 expression or function are linked to cancer including gastric cancer and colorectal cancer. It often shows reduced activity or expression in these cancers which associates with proteins like TGF-beta leading to impaired cell growth control. RUNX3 dysregulation is also connected to neurological disorders due to its role in neural development and function.

Target data

Forms the heterodimeric complex core-binding factor (CBF) with CBFB. RUNX members modulate the transcription of their target genes through recognizing the core consensus binding sequence 5'-TGTGGT-3', or very rarely, 5'-TGCGGT-3', within their regulatory regions via their runt domain, while CBFB is a non-DNA-binding regulatory subunit that allosterically enhances the sequence-specific DNA-binding capacity of RUNX. The heterodimers bind to the core site of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, LCK, IL3 and GM-CSF promoters (By similarity). May be involved in the control of cellular proliferation and/or differentiation. In association with ZFHX3, up-regulates CDKN1A promoter activity following TGF-beta stimulation (PubMed : 20599712). CBF complexes repress ZBTB7B transcription factor during cytotoxic (CD8+) T cell development. They bind to RUNX-binding sequence within the ZBTB7B locus acting as transcriptional silencer and allowing for cytotoxic T cell differentiation. CBF complexes binding to the transcriptional silencer is essential for recruitment of nuclear protein complexes that catalyze epigenetic modifications to establish epigenetic ZBTB7B silencing (By similarity). Necessary for the development and survival of sensory neurons expressing parvalbumin (By similarity).
