JNK (c-Jun N-terminal kinase)

JNK (c-Jun N-terminal kinase) is a type of protein that acts as a messenger inside cells, helping them respond to stress, inflammation, and other signals. When cells face challenges like injury, infection, or stress, JNK activates and influences how cells grow, survive, or die. It's involved in critical processes like immune responses, cell development, and even how cancer might progress. Essentially, JNK helps cells adapt to their environment by transmitting signals that regulate their behavior, playing a key role in maintaining health and responding to damage.
