Dynamic acetylation/deacetylation dictates TRIM27 nuclear-cytoplasmic localization for cancer progression
Listed in NCBI GEO
Cancer invasion and metastasis are governed by intricate molecular mechanisms.
Description
We demonstrate that TRIM27, an E3 ubiquitin ligase, plays dichotomous roles in cancer depending on its subcellular localization, which is controlled by acetylation/deacetylation at K297 independent of its ligase activity. Acetylation by GCN5 directs TRIM27 to the nucleus, while deacetylation by HDAC4 promotes cytoplasmic localization and cell proliferation.
Nuclear TRIM27 binds PARP1 and NELFs, represses PARP1-mediated NELFA ADP-ribosylation, maintains RNA polymerase II pausing, and suppresses PAX6 transcription, thereby inhibiting cancer invasion and metastasis.
