![]() | ![]() Title: The dynamics of signal triggering in a gp130-receptor complex. Authors: Rishi Matadeen / Wai-Ching Hon / John K Heath / E Yvonne Jones / Stephen Fuller / ![]() Abstract: gp130 is a shared signal-transducing membrane-associated receptor for several hematopoietic cytokines. The 30 A resolution cryo-electron microscopy (cryo-EM) structure of the Interleukin 11(IL-11)-IL- ...gp130 is a shared signal-transducing membrane-associated receptor for several hematopoietic cytokines. The 30 A resolution cryo-electron microscopy (cryo-EM) structure of the Interleukin 11(IL-11)-IL-11 Receptor-gp130 extracellular complex reveals the architecture and dynamics of this gp130-containing signaling complex. Normal-mode analysis reveals a repertoire of conformational changes that could function in signal triggering. This suggests a concerted mechanism of signaling involving all the components of the complex. This could provide a general mechanism of signal transfer for cytokines utilizing the JAK-STAT signaling cascade. | |||||||||
