BCL-2 gene inhibitory element binding factor

Year	Description
1995	Invention patented by John C. Reed and Masayoshi Harigai on February 15th, 1995. Abstract: The present invention provides a bcl-2 gene inhibitory element (BIE), which can inhibit expression of a gene in position-dependent and orientation-dependent manner. The invention provides, for example, BIE-1, having the nucleotide sequence 5'-CAAGAATGCAA-3' (SEQ ID NO: 1), which acts in an orientation-dependent and position-dependent manner to down-regulate the expression of the bcl-2 gene. The invention also provides a BIE binding factor (BBF), which is a cellular factor that can bind to a BIE. The invention provides, for example, BBF-A, which binds to BIE-1, including a nucleic acid sequence (SEQ ID NO: 8) encoding a portion of the amino acid sequence (SEQ ID NO: 9) of BBF-A. The invention further provides an antibody that specifically binds BBF-A. The invention also provides screening assays for identifying agents that can increase or decrease the binding of a BBF to a BIE, modulate the expression of a nucleic acid molecule linked to a BIE or modulate apoptosis in a cell.
