What's a GeneRIF?

Double mutant mice homozygous for the Mlh3DN/DN and Mus81-/- mutations show losses in chiasmata close to those observed in Mlh3-/- males, indicating that the MUS81-EME1-regulated crossover pathway can only partially account for the increased residual chiasmata in Mlh3DN/DN spermatocytes
Title: A mutation in the endonuclease domain of mouse MLH3 reveals novel roles for MutLγ during crossover formation in meiotic prophase I.
Study found that a Gen1 mutation alone did not affect DNA repair or meiotic recombination in mice; it caused synthetic lethality when combined with Eme1 mutations at an early embryonic stage. Also, combination of Gen1 and Eme1 mutations makes embryonic fibroblasts more sensitive to DNA damage & mice less capable of meiotic recombination. These results indicate that Gen1 and Eme1 are functionally redundant in mice.
Title: Gen1 and Eme1 Play Redundant Roles in DNA Repair and Meiotic Recombination in Mice.
indicate that SLX1 and MUS81-EME1 nucleases act together to resolve Holliday junctions (HJs) in a manner that requires tethering to SLX4.
Title: Cooperative control of holliday junction resolution and DNA repair by the SLX1 and MUS81-EME1 nucleases.
These findings link Eme1 with the replication-associated chromatin modifier functions of Np95 in the cellular response to DNA damage.
Title: Interplay between Np95 and Eme1 in the DNA damage response.
Mus81-Eme1- and Rad54-mediated homologous recombination are involved in the same DNA replication-dependent interstrand crosslinks repair pathway
Title: The structure-specific endonuclease Mus81-Eme1 promotes conversion of interstrand DNA crosslinks into double-strands breaks.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
