p38 MAP Kinases are a group of proteins that play a crucial role in cellular responses to stress, inflammation, and other stimuli. They are part of the mitogen-activated protein kinase (MAPK) signaling pathway, which helps cells communicate and adapt to changes in their environment. These kinases are activated by various factors, including cytokines and environmental stressors, leading to a cascade of cellular events. p38 MAP Kinases are involved in regulating processes such as cell differentiation, apoptosis, and the immune response, making them important for maintaining cellular health and function.
