Crystal structure of the human MUS81-EME2 complex.
Title: Crystal structure of the human MUS81-EME2 complex.
Avoiding damage formation through invalidation of Mus81-Eme2 and Mre11, or preventing damage signaling by turning off the ATM pathway, suppresses the replication phenotypes of Chk1-deficient cells.
Title: Signaling from Mus81-Eme2-Dependent DNA Damage Elicited by Chk1 Deficiency Modulates Replication Fork Speed and Origin Usage.
Results define distinct and temporal roles for MUS81-EME1 and MUS81-EME2 in the maintenance of genome stability.
Title: MUS81-EME2 promotes replication fork restart.
The presence of a 5' phosphate terminus at nicks and gaps rendered DNA significantly less susceptible to the cleavage by MUS81-EME2 than its absence.
Title: Human MUS81-EME2 can cleave a variety of DNA structures including intact Holliday junction and nicked duplex.
The results indicate that MUS81-EME2 is a more active endonuclease than MUS81-EME1 and exhibits broader substrate specificity.
Title: Substrate specificity of the MUS81-EME2 structure selective endonuclease.

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.
