摘要

The interleukin 2 receptor (IL-2R) generates proliferative signals in T lymphocytes by ligand-induced heterodimerization of two chains, IL-2Rβ and γ_c, which associate with the tyrosine kinases Jak1 and Jak3, respec- tively. Genetic and molecular studies have demonstrated that Jak3 is essential for mitogenic signaling by the γ_c chain; because it is also the only molecule known to associate with γ_c, we speculated that Jak3 might be sufficient for signaling by this chain.
