The death associated protein (DAP) kinase homologue Dlk/ZIP kinase induces p19ARF- and p53-independent apoptosis.

Dlk/ZIP kinase is one of five members of the death associated protein (DAP) kinase family. DAP kinase is able to induce apoptosis in a p19ARF/p53-dependent manner. We elucidated the potential role of the p19ARF/p53 pathway in Dlk/ZIP kinase-triggered cell death. Overexpression of a constitutively pro-apoptotic form of Dlk/ZIP kinase induced apoptosis in rat fibroblast cells which express wild-type p19ARF and p53. Cell death was characterised by apoptotic membrane blebbing, mitochondrial depolarisation, cytochrome c release and activation of caspase-3. However, Dlk/ZIP kinase- triggered cell death was also observed in p19ARF-deficient and p53-deficient mouse fibroblast cells. Quantitative analysis revealed that the status of p53 had no major influence on cellular susceptibility to Dlk/ZIP kinase-triggered cell death. Loss of p53 did not prevent Dlk/ZIP kinase- induced mitochondrial membrane depolarisation and release of cytochrome c. Furthermore, overexpression of Dlk/ZIP kinase did not lead to an increased expression of pro-apoptotic p53 target genes in either cell line. These data suggest that Dlk/ZIP kinase is able to trigger the mitochondrial apoptosis pathway independent of the p19ARF/p53 signalling pathway.[1]
