IL2RA蛋白背景綜述

Interleukin 2 receptor alpha (IL2Rα), also known as CD25 molecule, is a type I transmembrane glycoprotein with a signal peptide, an extracellular region, a transmembrane region, and a cytoplasmic domain. IL2Rα / CD25 is expressed on activated T cells and regulatory T cells, and is capable of binding IL2 with low affinity by itself. However, a ligand-induced high affinity heterotrimeric receptor complex is produced when IL2Rα is associated non-covelently with the IL2 receptor beta and gamma chain, and subsequently initiates the intacellular signal pathways such as MAPK or JAK/STAT. Accordingly, IL2 receptor complex mediates the IL2 effects via regulating T cell proliferation, activation and other lymphoid functions, and IL2Rα has been shown to deliver IL2 to the signaling complex and act as a regulator of signal transduction. In addition, IL2 induces IL2R transcription via an IL2-responsive enhancer, and IL2R also inhibits IL2 gene expression by activating the expression of CTLA-4 or FOXP3 via the negative feedback loops.
