DNA replication licensing factor Mcm5; Acts as component of the Mcm2-7 complex (Mcm complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the Mcm2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differential [...]

Dis3 like 3'-5' exoribonuclease 2 (Dis3l2) encodes a 3'-5'-exoribonuclease involved in catabolism of miRNA and tRNA; Belongs to the RNR ribonuclease family.

Exonuclease 1; 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for DNA mismatch repair (MMR) (By similarity).

Proliferating cell nuclear antigen; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. Belongs to the PCNA family.

Recombination repair protein 1; Plays a role in the cellular response to oxidative stress by promoting DNA repair mechanisms such as base excision repair and possibly homologous recombination repair. Functions as an apurinic/apyrimidinic (AP) endodeoxyribonuclease in the DNA base excision repair (BER) pathway of DNA lesions induced by oxidative and alkylating agents. Likely to initiate repair of AP sites in DNA by catalyzing hydrolytic incision of the phosphodiester backbone immediately adjacent to the damage, generating a single-strand break with 5'-deoxyribose phosphate and 3'-hydrox [...]

ATP-dependent DNA helicase II subunit 2; Ku80 (Ku80) encodes a protein that forms a Ku heterodimer with the product of Irbp, which binds to DNA double-strand break ends and is required for the non-homologous end joining pathway of DNA repair.

Putative lipoyltransferase 2, mitochondrial; Catalyzes the transfer of endogenously produced octanoic acid from octanoyl-acyl-carrier-protein onto the lipoyl domains of lipoate- dependent enzymes. Lipoyl-ACP can also act as a substrate although octanoyl-ACP is likely to be the physiological substrate (By similarity).

Protein MCM10 homolog; Proposed to be involved in DNA replication and to participate in the activation of the pre-replication complex (pre-RC). May be involved in chromosome condensation.

RecQ4 helicase (RecQ4) encodes an important protein for genome stability and DNA metabolism. It can utilize energy from ATP hydrolysis to help the DNA strand separation and exchange, playing a critical role in replication and repair.
