Transdominant negative proto-oncogene

摘要

The present invention provides a transrepressing protein of the Fos proto-oncogene family. The protein, FosB2, is characterized by having a leucine zipper domain and forming a heterodimer with a Jun related protein. This heterodimer is capable of binding to an AP-1 site and suppressing transcriptional transactivation of a promoter containing the AP-1 site.
