The tyrosine kinases Jak1 and Jak3 are known to be associated with the β and γ chains of interleukin‐2 receptor (IL‐2R). They are activated by stimulation with IL‐2, IL‐4, IL‐7, IL‐9, or IL‐15, receptors of which share the γ chain of the IL‐2R. We have obtained direct evidence of Jak1 association with the α chains of receptors for IL‐4, IL‐7 and IL‐9 and with the β chain of IL‐2R, which is also common to the IL‐15R. Furthermore, we have prepared mutant IL‐2R β chains with a mutation in the box 1 region, which is conserved among the IL‐2R β chain and the α chains of the other cytokine receptors sharing the IL‐2R γ chain. Using MOLT‐4 transfectants with the mutant β chains, we found that two conserved proline residues within the box 1 region are essentially involved in association with Jak1. The MOLT‐4 transfectants with the mutant β chains lacking Jak1 association showed IL‐2 responsiveness, in terms of activation of Jak3 and Stat5 and induction of cell growth, indicating that Jak1 is dispensable for IL‐2‐mediated cell growth signaling and that Jak1 activation is not required for activation of Jak3 and Stat5 in the MOLT‐4 transfectants.
