abstractText | SUMOylation promotes targeting of HP1alpha to pericentric heterochromatin. Here we identify the SUMO-specific protease SENP7 in mouse as a maintenance factor for HP1alpha accumulation at this location. SENP7 interacts directly with HP1alpha, localizes at HP1-enriched pericentric domains and can deconjugate SUMOylated HP1alpha in vivo. Depletion of SENP7 delocalizes HP1alpha from pericentric heterochromatin without affecting H3K9me3 levels. We propose that following targeting of HP1alpha, a subsequent deSUMOylation event enables HP1alpha retention at these domains. |
