Biological function summary
JAK3 is instrumental in the signaling mechanism of the immune system. It participates in the activation of various interleukins specifically those that signal through the common gamma chain receptor complex. JAK3's role is essential in the proper functioning and development of immune cells such as T cells and natural killer cells. Within this framework JAK3 pairs with cytokine receptors transmitting signals that regulate both proliferation and differentiation of these immune cells.
Pathways
JAK3 integrates into JAK-STAT signaling pathways. This protein works alongside STAT proteins including STAT5 to facilitate the transcription of genes involved in cell survival and proliferation. It also interacts with JAK1 another member of the Janus kinase family to form functional complexes. These interactions are pivotal in maintaining normal immune responses and ensuring that signaling pathways are activated appropriately in response to extracellular cues.
一般的な情報
機能
Non-receptor tyrosine kinase involved in various processes such as cell growth, development, or differentiation. Mediates essential signaling events in both innate and adaptive immunity and plays a crucial role in hematopoiesis during T-cells development. In the cytoplasm, plays a pivotal role in signal transduction via its association with type I receptors sharing the common subunit gamma such as IL2R, IL4R, IL7R, IL9R, IL15R and IL21R. Following ligand binding to cell surface receptors, phosphorylates specific tyrosine residues on the cytoplasmic tails of the receptor, creating docking sites for STATs proteins. Subsequently, phosphorylates the STATs proteins once they are recruited to the receptor. Phosphorylated STATs then form homodimer or heterodimers and translocate to the nucleus to activate gene transcription. For example, upon IL2R activation by IL2, JAK1 and JAK3 molecules bind to IL2R beta (IL2RB) and gamma chain (IL2RG) subunits inducing the tyrosine phosphorylation of both receptor subunits on their cytoplasmic domain. Then, STAT5A and STAT5B are recruited, phosphorylated and activated by JAK1 and JAK3. Once activated, dimerized STAT5 translocates to the nucleus and promotes the transcription of specific target genes in a cytokine-specific fashion.
