Model for relief of the NCoR-dependent checkpoint on AP-1 target genes. Signal-dependent phosphorylation of c-Jun results in TBLR1-dependent recruitment of UbcH5 and proteolytic removal of the NCoR/HDAC3 complex. This procedure allows binding of c-Jun/c-Fos heterodimers and transcriptional activation.
