    enzyme involved in cell signaling and immune response

    Janus Kinase (JAK) is a type of enzyme that plays a crucial role in the signaling pathways of cells, particularly in the immune system. It helps transmit signals from various cytokines and growth factors to the cell nucleus, influencing cell growth, survival, development, and differentiation. Dysregulation of JAK activity is associated with various diseases, including certain types of alopecia and autoimmune disorders, making it a target for specific therapeutic drugs known as JAK inhibitors.
