Transcription factor 20 is a protein that in humans is encoded by the TCF20 gene.^[3][4][5]

The protein encoded by this gene binds a platelet-derived growth factor-responsive element in the matrix metalloproteinase 3 (stromelysin 1) promoter. The protein localizes to the nucleus and displays DNA-binding and transactivation activities. It is thought to be a transcriptional coactivator, enhancing the activity of transcription factors such as JUN and SP1. Alternative splicing results in two transcript variants encoding different isoforms.^[5]

Interactions

TCF20 has been shown to interact with RNF4.^[6]
