Replication factor A protein 1; As part of the replication protein A (RPA/RP-A), a single- stranded DNA-binding heterotrimeric complex, may play an essential role in DNA replication, recombination and repair. Binds and stabilizes single-stranded DNA intermediates, preventing complementary DNA reannealing and recruiting different proteins involved in DNA metabolism; Belongs to the replication factor A protein 1 family.

Serine/threonine-protein kinase mph1; Involved in the regulation of the onset of mitosis. Involved in a pathway that coordinates cell proliferation and differentiation. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.

DNA topoisomerase 3; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. Fina [...]

Swi5-dependent recombination DNA repair protein 1; Involved in DNA recombination repair and meiotic chromosome segregation; Belongs to the SFR1/MEI5 family.

DNA repair protein rad8; Probable helicase, member of the UBC2/RAD6 epistasis group. Functions with DNA repair protein rad18 in error-free postreplication DNA repair. Involved in the maintenance of wild-type rates of instability of simple repetitive sequences such as poly(GT) repeats (By similarity). Plays a role in surviving topoisomerase-mediated DNA damage.

DNA repair protein rhp51; Required both for recombination and for the repair of DNA damage caused by X-rays. Binds to single and double-stranded DNA, in the presence of magnesium, and exhibits DNA-dependent ATPase activity. Promotes DNA strand annealing and strand exchange via DNA recombinase activity and forms helical nucleoprotein filaments. Belongs to the RecA family. RAD51 subfamily.

ATP-dependent DNA helicase hus2/rqh1; Has a role in the repair of UV-induced DNA damage in G2 via recombination-mediated repair. Also has a role in the repair of infrared-induced double DNA strand breaks. Exhibits an ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction; Belongs to the helicase family. RecQ subfamily.

F-box DNA helicase protein 1; Involved in ATP-dependent DNA-unwinding in a 3' to 5' direction, and ATP-ase activities stimulated by the single-stranded DNA-binding protein ssb1. Essential for viability and normal growth of stationary phase cells and in the absence of either srs2 or rqh1 DNA helicase. Involved in DNA recombination repair of strand breaks and stalled or collapsed replication forks, on the rhp51-dependent pathway: promotes rhp51 filament dissolution from stalled forks, thereby inhibiting homologous recombination and preventing excessive recombination. Ubiquitination and D [...]

Meiotic recombination protein dmc1; Required for meiotic recombination and cell cycle progression. Binds to single and double-stranded DNA, in the presence of magnesium, and exhibits DNA-dependent ATPase activity. Promotes DNA strand annealing and strand exchange via DNA recombinase activity and forms helical and stacked ring nucleoprotein filaments. Belongs to the RecA family. DMC1 subfamily.
