Transcription factor E2F DNA-binding domain inhibitor peptides and their use

   
   

The present invention provides peptides which bind to the DNA binding domain of transcription factor E2F, and inhibit cell cycle progression. Peptides include FWLRFT (SEQ ID NO:1); WVRWHF (SEQ ID NO:2); WHFIFW (SEQ ID NO:3); IWLSGLSRGVWVSFP (SEQ ID NO:4); and GSRILTFRSGSWYAS (SEQ ID NO:5) and derivatives based upon these sequences. Compositions and the use of the peptides in inhibiting cell cycle progression, such as in uncontrolled cell proliferation, are also provided.

La présente invention fournit les peptides qui lient au domaine obligatoire d'ADN du facteur E2F de transcription, et empêche la progression de cycle de cellules. Les peptides incluent FWLRFT (identification SEQ NO:1) ; WVRWHF (IDENTIFICATION SEQ NO:2) ; WHFIFW (IDENTIFICATION SEQ NO:3) ; IWLSGLSRGVWVSFP (IDENTIFICATION SEQ NO:4) ; et GSRILTFRSGSWYAS (identification SEQ NO:5) et dérivés basés sur ces ordres. Les compositions et l'utilisation des peptides en cellule empêchante font un cycle la progression, comme dans la prolifération non contrôlée de cellules, sont également fournies.
