There is provided an isolated and purified BNIP3 protein. There is also provided a method for inducing necrosis in cells by transfecting a cell with a BNIP3 protein. A method for inducing necrosis in cells by creating a transgene overexpressing the gene for the BNIP3 protein is also provided. A transgenic animal and progeny thereof is provided having an expression factor consisting essentially of a BNIP3 protein selected from the group consisting essentially of Seq. ID 1 and 2. Also provided is a vector for use in treating disease including BNIP3 or DN NIP and a promoter. A gene therapy having DNA encoding BNIP3 or DN NIP and a promoter, whereby said gene therapy is used to induce necrosis or inhibit necrosis is also provided.
