General annotation (Comments)

Function

Transcription factor that binds to a symmetrical DNA sequence (E-boxes) (5'-CACGTG-3') that is found in a variety of viral and cellular promoters.

Subunit structure

Interacts with MAF By similarity. Efficient DNA binding requires dimerization with another bHLH protein. Binds DNA as an homodimer or a heterodimer (USF1/USF2). In vivo, the USF1/USF2A heterodimer represents over 66% of the usf binding activity whereas the USF1 and USF2A homodimers represent less than 10%. The USF1/USF2B heterodimer accounted for almost 15% in some cell.

Subcellular location

Nucleus.

Tissue specificity

Ubiquitous.

Sequence similarities

Contains 1 basic helix-loop-helix (bHLH) domain.
