Overview of Gene Research
Dap, short for Death-associated protein kinase, is a calcium/calmodulin-dependent serine/threonine kinase. It plays a crucial role in several cell death pathways such as apoptosis and programmed necrosis, and is also identified as an essential regulator of autophagy, a cellular self-degradation process [1]. It is associated with the cell cytoskeleton and has ankyrin repeats and a 'death' domain in its structure.
Functional studies suggest that Dap-kinase may direct autophagy specifically towards autophagic cell death. It has been mapped to distinct stages in autophagy signaling, including interactions with the Beclin-1/phosphatidylinositol 3-kinase (PI(3)K) complex necessary for autophagosome formation, and with the LC3-binding protein, MAP1B, which may regulate vesicle trafficking [1]. Also, Dap-kinase exerts apoptotic effects by suppressing integrin functions and integrin-mediated survival signals, thereby activating a p53-dependent apoptotic pathway [2]. In terms of tumor-related research, lung carcinoma clones with highly aggressive metastatic behavior did not express Dap-kinase, while restoration of Dap-kinase to physiological levels in high-metastatic Lewis carcinoma cells suppressed their ability to form lung metastases and delayed local tumor growth [3].
In conclusion, Dap plays significant roles in apoptosis, autophagy, and metastasis-related processes. The functional studies on Dap-kinase, especially those using in vivo models like the ones with Lewis carcinoma cells, contribute to understanding its role in tumor-related diseases, potentially providing new insights for cancer treatment strategies.
