c-Jun N-terminal kinase (JNK)

JNK, or c-Jun N-terminal kinase, is a type of enzyme involved in cell signaling. It helps cells respond to stress, such as injury or inflammation, by transmitting signals that can influence cell growth, survival, or death. JNK is part of the body's way of maintaining balance when faced with challenging conditions. While essential for normal function, overactivation of JNK has been linked to diseases like cancer and neurodegeneration. Overall, JNK acts as a molecular sensor and responder, helping cells adapt or trigger protective or harmful responses depending on the situation.
