PTEN promoter and its transcription
factors. PTEN’s full-length promoter
lies between 1344 and 745 (gray bar), while the minimal promoter lies between
958 and 821 (black bar). Four transcription factors are known to directly
bind upstream of PTEN: PPARγ (solid gray bar), USF1 (stripped gray bar),
p53 (dotted gray bar), and EGR1 (dashed gray bar).
