Accumulation and Phosphorylation of RecQ-Mediated Genome Instability Protein 1 (RMI1) at Serine 284 and Serine 292 during Mitosis.
Li et al., Tianjin, China. In Int J Mol Sci, 2014
BTR complex, composed of BLM, topoisomerase IIIα (Topo IIIα), RMI1 (RecQ-mediated genome instability protein 1, BLAP75) and RMI2 (RecQ-mediated genome instability protein 2, BLAP18), is crucial for maintaining genome stability.
DNA2 cooperates with the WRN and BLM RecQ helicases to mediate long-range DNA end resection in human cells.
Janscak et al., Zürich, Switzerland. In J Biol Chem, 2014
In addition, we present in vitro and in vivo data suggesting that BLM promotes DNA end resection as part of the BLM-TOPOIIIα-RMI1-RMI2 complex.
Holliday junction processing enzymes as guardians of genome stability.
West et al., London, United Kingdom. In Trends Biochem Sci, 2014
In mammalian cells, HJs are processed by the BTR (BLM-topoisomerase IIIα-RMI1-RMI2) complex, the SLX-MUS (SLX1-SLX4-MUS81-EME1) complex, and the GEN1 resolvase.

West et al., London, United Kingdom. In Genes Dev, 2014
Three pathways for HJ processing exist in human cells and involve the following enzymes/complexes: BLM-TopoIIIα-RMI1-RMI2 (BTR complex), SLX1-SLX4-MUS81-EME1 (SLX-MUS complex), and GEN1.
Molecular mechanism of double Holliday junction dissolution.
Costa et al., London, United Kingdom. In Cell Biosci, 2013
Within the dissolvasome, the RecQ-like BLM helicase provides the translocase function for Holliday junction migration, while the topoisomerase III alpha-RMI1 subcomplex works as a proficient DNA decatenase, together resulting in double-Holliday-junction unlinking.
