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) (1-2). 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 (3). A fragment of the cDNA when expressed as a mini-protein of 28kD protects the cell from IFN-g induced apoptosis. The full-length DAP-5 cDNA codes for a protein of approximate molecular weight of 97kD. Low level of expression protects the cells, whereas high level of expression results in cell death (3-4). Positive Control: Jurkat Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
