| Primary Identifier | IPR042530 | Type | Homologous_superfamily |
| Short Name | EME1/EME2_C |
| description | This superfamily includes the C-terminal domain found in Eme1 from fission yeasts, and EME1/EME2 from animals. They interact with Mus81 to from a complex, which acts as a structure-specific endonuclease that targets branched DNA structures with a 5'-end at the branch nick [, ]. The typical substrates of this complex include 3'-flap structures, replication forks and nicked Holliday junctions [, ].Similar to MUS81-EME1, human MUS81-EME2 cleaves 3'-flaps, replication forks and nicked Holliday junctions, and exhibits limited endonuclease activity with intact Holliday junctions. However, MUS81-EME2 can also cleave a variety of DNA structures including D-loop recombination intermediates and nicked duplex [, ].Both Mus81 and Eme1 consist of a central nuclease domain, two repeats of the helix-hairpin-helix (HhH) motif at their C-terminal region, and a linker helix []. |
