The length of the interleukin-11 receptor stalk determines its capacity for classic signaling.

ABSTRACT: Interleukin (IL)-11 is a multifunctional cytokine that was traditionally recognized for its hematopoietic and anti-inflammatory functions, but has recently been shown also to be involved in tumorigenesis. IL-11 signaling is initiated by binding of the cytokine to the IL-11 receptor (IL-11R), which is not directly involved in signaling but required for IL-11 binding to the signal-transducing receptor glycoprotein (gp) 130. In classic signaling, IL-11 binds to the membrane-bound IL-11R to initiate signal transduction. Additionally, IL-11 signaling can be initiated via soluble IL-11R, known as trans-signaling, and this pathway only requires the three extracellular domains of the IL-11R, but not stalk, transmembrane, or intracellular region. Here, we analyzed the role of the IL-11R stalk regio
