Apoptosis, or programmed cell death, occurs during normal cellular differentiation and development of multicellular organisms. Recently, five novel apoptotic genes (named DAP genes for: Death Associated Proteins) have been identified that code for proteins, which display a diverse spectrum of biochemical activities. These include a novel type of calcium/calmodulin-regulated kinase, which carries ankyrin repeats and a death domain (DAP-kinase), a nucleotide-binding protein (DAP-3), a small proline-rich cytoplasmic protein (DAP-1), and a novel homolog of the eIF4G translation initiation factor (DAP-5). DAP-5 (also named p97 and NAT1) is a ubiquitously expressed member of the translation initiation factor eIF4G family that lacks the eIF4E binding site. DAP-5 was cloned from HeLa cells using a functional approach in attempt to isolate cDNA fragments, which convey resistance to gamma interferon (IFN-g)-induced programmed cell death. A fragment of the cDNA when expressed as a mini-protein of 28 kDa protects the cell from IFN-g induced apoptosis. The full-length DAP-5 cDNA codes for a protein of approximate molecular weight of 97 kDa. Low level of expression protects the cells, whereas high level of expression results in cell death (3-4).
