Protein

Crossover junction endonuclease MMS4

Gene
MMS4, SLX2, YBR098W, YBR0826, YBR0829, YBR100W
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Interacts with MUS81 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. Typical substrates include 3'-flap structures, D-loops, replication forks with regressed leading strands and nicked Holliday junctions. Cleavage probably occurs approximately half a helical turn upstream of the free 5'-end in these structures. May be required in mitosis for the processing of stalled replication fork intermediates arising spontaneously or subsequent to treatment with DNA damaging agents such as methylmethane sulfonate (MMS), camptothecin (CPT) or UV. May be required in meiosis for the repair of meiosis-specific double strand breaks subsequent to single-end invasion (SEI). This involves consecutive cleavage of D-loops and nicked Holliday junctions leading to sister chromatid crossover. In contrast to MSH4-MSH5 dependent crossover, double Holliday junctions do not seem to be involved. Spore formation and viability are severely impaired in deletion strains.11 Publications

Miscellaneousi

Miscellaneous

Two distinct classes of meiotic crossovers have been demonstrated in budding yeast. Class I crossovers exhibit crossover interference and require MSH4 and MSH5 for their resolution, while class II crossovers exhibit no crossover interference and require MUS81 and MMS4. While class I crossovers represent the majority of crossovers in S.cerevisiae, they are virtually absent in S.pombe which lacks orthologs of MSH4 and MSH5.
