Hedgehog (Hh) pathway plays a pivotal role in diverse aspects of development and postnatal physiology. Perturbation of Hh signaling and activation of GLI1 (glioma-associated oncogene 1), a dedicated transcription factor for Hh pathway, are highly associated with several cancers, such as medulloblastoma and basal cell carcinoma. Dynamic and precise control of GLI1 activity is thus important to ensure proper homeostasis and tumorigenesis. Here we show that MEKK2 (MAP3K2) and MEKK3 (MAP3K3) inhibit GLI1 transcriptional activity and oncogenic function through phosphorylation on multiple Ser/Thr sites of GLI1, which reduces GLI1 protein stability, DNA-binding ability, and increases the association of GLI1 with SUFU. Interestingly, MEKK2 and MEKK3 are responsible for FGF2-mediated inhibition on Hh signaling. Moreover, expression of MEKK2 and MEKK3 inhibits medulloblastoma cell proliferation and negatively correlates with Hh pathway activity in medulloblastoma clinical samples. Together, these findings reveal a novel noncanonical GLI1 regulation and provide a potential therapeutic target for the treatment of cancers with aberrant Hh pathway activation, such as medulloblastoma.
