Reaction: IL21 receptor JAK phosphorylation

- in pathway: Interleukin-21 signaling
The IL21 heteromeric receptor complex can activate JAK1 and JAK3 in response to Interleukin-21 (IL21), leading to JAK tyrosine phosphorylation (Asao et al. 2001, Habib et al. 2002).

This is a black box event because the mechanism leading to JAK phosphorylation is not established for this receptor complex.
