RMI1

NCE4, L000004399, YPL024W
Subunit of the RecQ (Sgs1p) - Topo III (Top3p) complex; stimulates superhelical relaxing, DNA catenation/decatenation and ssDNA binding activities of Top3p; involved in response to DNA damage; functions in S phase-mediated cohesion establishment via a pathway involving the Ctf18-RFC complex and Mrc1p; stimulates Top3p DNA catenation/decatenation activity; null mutants display increased rates of recombination and delayed S phase
Saccharomyces cerevisiae (S288c)
PREY

SMC3

cohesin subunit SMC3, L000003992, YJL074C
Subunit of the multiprotein cohesin complex; required for sister chromatid cohesion in mitotic cells; also required, with Rec8p, for cohesion and recombination during meiosis; phylogenetically conserved SMC chromosomal ATPase family member
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Rmi1 functions in S phase-mediated cohesion establishment via a pathway involving the Ctf18-RFC complex and Mrc1.

Lai MS, Seki M, Tada S, Enomoto T

Saccharomyces cerevisiae RecQ helicase (Sgs1) combines with DNA topoisomerase III (Top3) and RecQ-mediated genome instability 1 (Rmi1) to form an evolutionarily conserved complex that is required for processing homologous recombination intermediates and restarting collapsed replication forks. It was previously reported that Rmi1 contributes to sister chromatid cohesion; however, the underlying molecular mechanism has been unclear. In the present study, Rmi1 ... [more]

Synthetic Lethality
Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
