MAP kinase signaling cascade plays an important role in the cellular response to various stress stimuli from the external environment. This signaling cascade is divided into three levels: MAP kinase kinase kinases (MAP3K) phosphorylate and thus activate MAP kinase kinases (MAP2K) and those subsequently phosphorylate and thus activate MAP kinase (MAPK) pathway, which regulates many cellular functions such as apoptosis, cell differentiation and morphogenesis. One of the important MAP3K is protein kinase ASK1 (Apoptosis signal-regulating kinase 1), which is an important regulator of cellular immune and stress responses. Given that the increased activity of ASK1 is related to the development of serious diseases such as cancer, cardiovascular and neurodegenerative diseases, ASK1 is an interesting target in the pharmacy in the development of new drugs. Human ASK1 consists of 1374 amino acids and is divided into three domains: a central Ser/Thr catalytic domain and two coiled-coil domains, of which the first is located at the N- and the second at the C-terminus of the molecule of this protein kinase. ASK1 is regulated by its binding partners, which include a small cellular redox protein thioredoxin (Trx-1), which binds to the N-terminal part of ASK1. Trx-1 is a potent antioxidant and so it protects cells...
