General Information

General Information Comment Organism
malfunction loss of SENP7 leads to an increased time spent in mitosis. Single PxVxL SENP7 mutants behave as dominant negatives Mus musculus
metabolism HP1 enrichment at pericentric heterochromatin is essential for proper chromosome segregation, the process requires H3K9me3 and the SUMO protease SENP7 Mus musculus
physiological function a short module comprising two consecutive HP1 interaction motifs on SENP7 is the determinant for HP1 enrichment and acts by restricting HP1 mobility at pericentric domains. Mechanism for maintenance of HP1 enrichment determination in which this module functions on top of H3K9me3 to lock contiguous HP1 molecules already docked on H3K9me3-modified nucleosomes, overview Mus musculus
