Recombinant Human Crossover junction endonuclease EME1 (EME1)

Uniprot Id

Q96AY2

Target Species

Human

Target Name

EME1

Target Full Name

Crossover junction endonuclease EME1

Target Function

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, replication forks and nicked Holliday junctions. May be required in mitosis for the processing of stalled or collapsed replication forks.

Target Subcellular Location

Nucleus, nucleolus. Note=Recruited to regions of DNA damage in S-phase cells.

Target Protein Families

EME1/MMS4 family

Target Background

This gene encodes a protein that complexes with methyl methanesulfonate-sensitive UV-sensitive 81 protein to form an endonuclease complex. The encoded protein interacts with specifc DNA structures including nicked Holliday junctions, 3'-flap structures and aberrant replication fork structures. This protein may be involved in repairing DNA damage and in maintaining genomic stability. Alternative splicing results in multiple transcript variants.
