1-formylisoquinoline thiosemicarbazone

Uses

IQ 1 disrupts Wnt signaling. IQ-1 in conjunction with Wnt3a has been shown to be sufficient to maintain murine embryonic stem cell proliferation in the absence of serum. Binds to the PR72/PR130 subunit of protein phosphatase PP2A preventing β-catenin from switching co-activator usage from CBP to p300 leading to an increase in β-catenin/CBP-driven transcription at the expense of β-catenin/p300-driven transcription.
