Abstract:
Death associated protein kinase (DAPK) is a calcium/calmodulin-regulated serine/threonine kinase; its main function is to regulate cell death. DAPK family proteins consist of DAPK1, DAPK2, DAPK3, DAPK-related apoptosis-inducing protein kinases (DRAK)-1 and DRAK-2. In this review, we discuss the roles and regulatory mechanisms of DAPK family members and their relevance to diseases. Furthermore, a special focus is given to several reports describing cross-talks between DAPKs and mitogen-activated protein kinases (MAPK) family members in various pathologies. We also discuss small molecule inhibitors of DAPKs and their potential as therapeutic targets against human diseases.
Insights
Death associated protein kinases (DAPK) regulate cell death and are implicated in diseases. This review explores DAPK family roles, regulation, cross-talk with MAPKs, and therapeutic potential of DAPK inhibitors.
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- Death associated protein kinase (DAPK) is a calcium/calmodulin-regulated serine/threonine kinase.
- The DAPK family includes DAPK1, DAPK2, DAPK3, and DRAK-1/DRAK-2.
- DAPK family members play crucial roles in regulating programmed cell death.
Purpose of the Study:
- To review the diverse roles and regulatory mechanisms of DAPK family members.
- To highlight the involvement of DAPKs in various human diseases.
- To examine the interplay between DAPKs and mitogen-activated protein kinases (MAPKs) in disease pathologies.
Main Methods:
- Literature review of studies on DAPK family proteins.
- Analysis of regulatory mechanisms and disease relevance.
- Investigation of cross-talk between DAPKs and MAPKs.
Main Results:
- DAPKs are key regulators of cell death pathways.
- Dysregulation of DAPKs is linked to several human diseases.
- Cross-talk between DAPKs and MAPKs influences disease progression.
Conclusions:
- DAPK family members are critical regulators of cell death with significant implications in disease.
- Understanding DAPK regulation and interactions, particularly with MAPKs, is vital.
- Small molecule inhibitors targeting DAPKs show promise for therapeutic interventions in human diseases.
