High impact information on PDS5

  • Pds5p regulates the maintenance of sister chromatid cohesion and is sumoylated to promote the dissolution of cohesion [1].
  • We report that pds5 mutants establish cohesion, but during mitosis exhibit precocious sister dissociation [1].
  • The PDS5 gene (precocious dissociation of sisters) was identified in a genetic screen designed to identify genes important for chromosome structure [2].
  • PDS5 is an essential gene and homologues are found from yeast to humans [2].
  • Pds5p is required to maintain cohesion at centromere proximal and distal sequences [2].

Biological context of PDS5


Anatomical context of PDS5

  • In HeLa cells, Pds5 proteins physically interact with cohesin and associate with chromatin in a cohesin-dependent manner [5].

Regulatory relationships of PDS5

  • TOP2 suppresses mini-chromosome loss in pds5 mutants indicating that it rescues a chromosome segregation defect [6].
