N2 - A variety of cytokines, lymphokines and growth factors functionsby interacting with receptors that are members of the cytokine receptor superfamily. These receptors share extracellular motifs and have limited similarity in their cytoplasmic domains. Although lacking catalytic domains, this family of receptors couples ligand binding with the induction of tyrosine phosphorylation. Recent studies have shown that this is mediated by members of the Janus kinase (JAK) family of cytoplasmic protein tyrosine kinases. JAKs physically associate with the membrane-proximal region of the ligand-bound-receptor, leading to their tyrosine phosphorylation and activation. The activated JAKs phosphorylate the receptors as well as cytoplasmic proteins belonging to a family of transcription factors called the signal transducers and activators of transcription (STATs), providing a novel signaling pathway that is shared by all members of the cytokine receptor superfamily.
