Lymphocytes expressing the<unk>  can form functional receptors for these cytokine proteins, which transmit signals from one cell to another and direct programs of cellular differentiation. Ligands The<unk><unk>  partners with other ligand-specific receptors to direct lymphocytes to respond to cytokines including IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21. Signalling IL2RG has been shown to interact with Janus kinase 3.
