Synonym: (add) promoter proximal region
Def: DNA segment that ranges from about -250 to -40 relative to +1 of RNA transcription start site, where sequence specific DNA-binding transcription factors binds, such as Sp1, CTF (CCAAT-binding transcription factor), and CBF (CCAAT-box binding factor).
Children: CTF binding site, CBF binding site, Sp1 binding site

Hi MeiYee
Is a CTF_binding_site always a part of a proximal promoter region or can it be part of other things?
Does a proximal promoter always have a part that is a CTF binding site?
I am trying to figure out what the relationship should be. part of or has part or neither
