Modulation of nongenomic activation of PI3K signalling by tetramerization of N-terminally-cleaved RXRα

Modulation of nongenomic activation of PI3K signalling by tetramerization of N-terminally-cleaved RXRα

The transcription factor retinoid X receptor-alpha (RXRα) can also form homotetramers. Here the authors show that the anti-cancer agent K-80003 selectively inhibits the nongenomic action of N-terminally-cleaved RXRα in tumour cells by stabilizing its tetramerization but not that of full-length RXRα....
