Abstract

Janus kinases (JAKs) initiate the intracellular signaling cascade triggered by exposure of cells to cytokines and interferons. In order to achieve this, JAKs are bound to the intracellular domain of specific cytokine receptors immediately adjacent to the cell membrane. In this issue of Structure, Ferrao et al. (2016) provide structural details of such an interaction and in doing so, identify for the first time the motif used by type II cytokine receptors to recruit JAK1.
