| 摘要 |
The present invention provides substantially pure proapoptotic dependence peptides. The peptides consist substantially of the sequence of an active dependence domain selected from the group of dependence polypeptides consisting of p75NTR, androgen receptor, DCC, huntingtin polypeptide, Machado-Joseph disease gene product, SCA1, SCA2, SCA6 and atrophin-1 polypeptide. Substantially pure proapoptotic dependence peptides include SATLDALLAALRRI (SEQ ID NO:3), Q14 (SEQ ID NO:7), SATLDALLAALGGI (SEQ ID NO:4), SATLDALLAALRGI (SEQ ID NO:5), SATLQALLAALRRI (SEQ ID NO:6), tat-GG-SATLDALLAALRRI (SEQ ID NO:37) and tat-GG-Q14 (SEQ ID NO:36).
