The IFNγ response pathway is associated with response to immunotherapy in cancer. Here the authors show that high levels of the IFNγ-receptor (IFNγ-R1) affect the outcome of immunotherapy in a context-dependent fashion and identify the E3 ubiquitin ligase STUB1 as a negative regulator of IFNγ-R1/JAK1 expression in cancer cells.
