CD40 — JAK1
Text-mined interactions from Literome
Atamas et al., J Immunol 2002
:
Immunoprecipitation-Western blotting experiments showed that phosphorylation levels of IL-4Ralpha,
Janus kinase 1 , insulin receptor substrate 1, and insulin receptor substrate 2, factors with molecular mass close to the observed 130 kDa major phosphorylation band, increased in
response to the combined
CD40 ligation and IL-4 action
Zhou et al., J Immunol 2003
:
Thus, in humans, IL-4 alone is sufficient to drive AID expression, and
CD40 signaling is required for optimal AID production ; IL-4 induced AID expression is mediated via the JAK/STAT signaling pathway, and can be negatively
regulated by the
JAK phosphatase activity of CD45
