"LEF-1 and TCF-4 sumoylation (by the SUMO ligase PIASy) represses LEF-1 activity by targeting it to nuclear bodies but enhances TCF-4 and beta-catenin transcription, while CBP mediated acetylation of TCF results in decreased TCF and beta-catenin-binding in Drosophila and increased TCF nuclear retention in nematodes, both leading to transcriptional repression."
