although fork rotation and precatenation facilitate unwinding in hard-to-replicate contexts, they intrinsically disrupt normal chromosome duplication and are therefore restricted by Timeless/Tipin
Title: Fork rotation and DNA precatenation are restricted during DNA replication to prevent chromosomal instability.
The replication stalling complex, Mrc1/Tof1/Csm3, reduces CAG repeat contraction rates independently of replication checkpoint and DNA damage checkpoint factors.
Title: Mrc1, Tof1 and Csm3 inhibit CAG.CTG repeat instability by at least two mechanisms.
Authors show that minisatellite length expansions are controlled by the products of the CSM3 and TOF1 genes, while contractions are controlled by MRC1.

Bouquet formation and rapid prophase movements depend on NDJ1, MPS3, and a new member of this pathway, CSM4, which encodes a meiosis-specific nuclear envelope protein required specifically for telomere mobility.
Title: Rapid telomere movement in meiotic prophase is promoted by NDJ1, MPS3, and CSM4 and is modulated by recombination.
analyzed sister-chromatid cohesion in double mutants of mrc1Delta, tof1Delta, and csm3Delta and identified additive cohesion defects that indicated the existence of at least two pathways that contribute to sister-chromatid cohesion
Title: Genetic dissection of parallel sister-chromatid cohesion pathways.
Data show that the Tof1/Csm3/Mrc1 checkpoint complex interacts directly with the MCM helicase during both replication fork progression and when the replication fork is stalled.
Title: Uncoupling of unwinding from DNA synthesis implies regulation of MCM helicase by Tof1/Mrc1/Csm3 checkpoint complex.
