Lecture "Structural basis of Apoptosis signal-regulating kinase 1 (ASK1) regulation"

24. 6. 2024, start: 15:00

Apoptosis signal-regulating kinase 1 (ASK1) is a crucial stress sensor, directing cells toward apoptosis, differentiation, and senescence via the p38 and JNK signaling pathways. ASK1 dysregulation has been associated with cancer and inflammatory, cardiovascular, and neurodegenerative diseases, among others. However, our limited knowledge of the underlying structural mechanism of ASK1 regulation hampers our ability to target this member of the MAP3K protein family towards developing therapeutic interventions for these disorders. Nevertheless, as a multidomain Ser/Thr protein kinase, ASK1 is regulated by a complex mechanism involving dimerization and interactions with several other proteins, including thioredoxin 1 (TRX1) and 14-3-3. This talk will discuss recent advances in the study of the molecular mechanism of ASK1 regulation and the role of protein-protein interactions in this process.
