title: Quality control of receptor-kinase signaling complexes.
abstract: The erythropoietin receptor transduces signals leading to the growth, differentiation, and survival of red blood cell precursors via interaction with Janus kinase 2 (JAK2). This interaction was thought to occur only at the plasma membrane. Recent evidence, however, shows that JAK2 assembles with newly synthesized erythropoietin receptors in the endoplasmic reticulum, and that this assembly is essential for efficient expression of the receptors at the cell surface.
