Immunochemical characterization and transacting properties of upstream stimulatory factor isoforms.

The Journal of biological chemistry - 19 Jan 1996

Viollet B, Lefrançois-Martinez A M, Henrion A, Kahn A, Raymondjean M, Martinez A

Abstract excerpt

The ubiquitous upstream stimulatory factor (USF) transcription factors encoded by two distinct genes (USF1 and USF2) exist under the form of various dimers able to bind E-boxes. We report the molecular cloning and functional characterization of USF2 isoforms, corresponding to a 44-kDa subunit, USF2a, and a new 38-kDa subunit, USF2b, generated by differential splicing. Using specific anti-USF antibodies, we define...
