RING1 inhibits transactivation of RBP-J by Notch through interaction with LIM protein KyoT2.


The DNA-binding protein recombination signal binding protein-Jkappa (RBP-J) mediates transcriptional activation of the Notch intracellular domain (NIC). In the absence of transcriptional activators, RBP-J suppresses transcription by recruiting co-suppressors. KyoT2 is a LIM domain protein that inhibits the RBP-J-mediated transcriptional activation. Here we… (More)
