The inference is based on the homology mapping from PANTHER. Briefly, reactions for which all involved PhysicalEntities (in input, output and catalyst) have a mapped orthologue/paralogue (for complexes at least 75% of components must have a mapping) are inferred to the other species. High level events are also inferred for these events to allow for easier navigation.

This interaction is E2F independent and is important for targeting of the condensin II complex to chromatin (Longworth et al. 2008). RB1 may be particularly important for targeting of the condensin II complex to centromeres (Manning et al. 2010). RB1 deficient cells exhibit chromosome condensation defects and are prone to aneuploidy caused by aberrant chromosomal segregation. Therefore, tumor suppressor role of RB1 is based both on E2F-dependent control of G1/S transition, as well as on E2F-independent maintenance of genomic stability through regulation of mitotic chromosome condensation (Longworth et al. 20008, Coschi et al. 2010, Manning et al. 2010).

The role of RB1 in the maintenance of genomic stability is supported by studies of the childhood eye cancer retinoblastoma and its precursor, retinoma. Retinoma, a quiescent precursor of malignant retinoblastoma with functional loss of both RB1 alleles, is genomically unstable (Dimaras et al. 2008). Also, while the majority of retinoblastoma tumors are caused by the loss-of-function of the tumor suppressor gene RB1, ~2% of retinoblastoma tumors in unilaterally affected patients are initiated by a high level amplification of MYCN gene, in the presence of two functional, unmutated RB1 alleles. These tumors, with normal RB1 and amplified MYCN show a much lower level of genomic instability than retinoblastoma tumors with RB1 loss-of-function (Rushlow et al. 2013).

MCPH1 binding sequesters condensin II by preventing loading of condensin II on chromatin. Simultaneous binding of MCPH1 to the SET oncogene may contribute to condensin II sequestering (Leung et al. 2011). Mutations in MCPH1 are a cause of microchephaly inhereted in an autosomally recessive manner.

The condensin II complex subunit NCAPD3 binds monomethylated histone H4 (H4K20me1), thereby associating with chromatin (Liu et al. 2010). Binding of the condensin II complex to chromatin is partially controlled by the presence of RB1 (Longworth et al. 2008).

Two mechanisms contribute to the accumulation of H4K20me1 at mitotic entry. First, the activity of SETD8 histone methyltransferase peaks at G2/M transition (Nishioka et al. 2002, Rice et al. 2002, Wu et al. 2010). Second, the complex of CDK1 and cyclin B1 (CDK1:CCNB1) phosphorylates PHF8 histone demethylase at the start of mitosis, removing it from chromatin (Liu et al. 2010).

Condensin II complex needs to be phosphorylated by the CDK1:CCNB1 complex, and then phosphorylated by PLK1, in order to efficiently condense prophase chromosomes (Abe et al. 2011).
