Fig. 2: CK-CKR Interaction interfaces in CytoSIP.
From: CytoSIP: an annotated structural atlas for interactions involving cytokines or cytokine receptors

IL4 interaction with three different CKRs. CKs are colored in yellow, and CKRs are colored in light gray. All the interactions of each CK or CKR can be found on the corresponding page in CytoSIP. a Interaction interface of IL4 with IL4RA, IL2RG (PDB ID: 3BQL). b Interaction interface of IL4 with IL13RA (PDB ID: 3BQN). c Interaction interface of IL4RA with IL13 (PDB ID: 3BPO).
