J JAKS cooperation with STATs (signal transducers and activators of transcription). Cytokines 3 JAKS are janus kinases, which are cytoplasmic tyrosine kinases that mediate signal transduction by cytokine receptors. JAKS physically interact with cytokine receptors and are activated by cytokine binding. There are four known mammalian JAKS: JAK1, JAK2, JAK3, and Tyk2. Interferon-γ Jun NH2-Terminal Kinase Jun NH2-terminal kinase (JNK) is mitogenic activated protein (MAP) kinase involved with c-Jun phosphorylation and activation of NF-κB. Interleukin-1β (IL-1β) 3 3 A family of non-receptor protein tyrosin kinases of approximately 130 kDa, consisting of JAK1 (Janus kinase-1), JAK2 (Janus kinase-2), JAK3 (Janus kinase-3), and TyK2 (tyrosine kinase-2).They play a crucial role in the initial steps of cytokine signaling, in Juvenile Periodontitis Juvenile periodontitis is an aggressive and destructive inflammatory disease of the connective tissue of gums affecting adolescents and young adults.
