Protein timeless; Required for the production of circadian rhythms. The biological cycle depends on the rhythmic formation and nuclear localization of the TIM-PER complex. Light induces the degradation of TIM, which promotes elimination of PER. Nuclear activity of the heterodimer coordinatively regulates PER and TIM transcription through a negative feedback loop. Behaves as a negative element in circadian transcriptional loop. Does not appear to bind DNA, suggesting indirect transcriptional inhibition. Belongs to the timeless family.

CDC45L (CDC45L) encodes a protein that contributes to 3'-5' DNA helicase activity of the Cdc45/Mcm2-7/GINS complex. It is involved in chromosome condensation and the regulation of the mitotic G1/S transition.

Serine/threonine-protein kinase grp; Serine/threonine-protein kinase which is required for checkpoint-mediated cell cycle arrest and activation of DNA repair in response to the presence of DNA damage or unreplicated DNA. May also negatively regulate cell cycle progression during unperturbed cell cycles. May phosphorylate the CDC25 phosphatase stg, which promotes its degradation. This results in increased inhibitory tyrosine phosphorylation of Cdk1-cyclin complexes and consequent inhibition of cell cycle progression. Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase [...]

DNA replication licensing factor Mcm2; 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 [...]

Replication protein A 70 kDa DNA-binding subunit; As part of the heterotrimeric replication protein A complex (RPA/RP-A), binds and stabilizes single-stranded DNA intermediates, that form during DNA replication or upon DNA stress. It prevents their reannealing and in parallel, recruits and activates different proteins and complexes involved in DNA metabolism. Thereby, it plays an essential role both in DNA replication and the cellular response to DNA damage.

Mutagen-sensitive 101 (mus101) encodes a protein involved in the DNA replication checkpoint during mitosis.

Replication protein A3 (RPA3) encodes a protein involved in the maintenance of the neuronal stem cell population.

DNA polymerase epsilon catalytic subunit 1; Catalytic component of the DNA polymerase epsilon complex. Participates in chromosomal DNA replication. Required during synthesis of the leading DNA strands at the replication fork, binds at/or near replication origins and moves along DNA with the replication fork (By similarity). Has 3'-5' proofreading exonuclease activity that corrects errors arising during DNA replication. Has a role in the G1-S transition and/or S-phase progression of the mitotic cycle and endocycle progression. Involved in DNA synthesis during DNA repair (By similarity). [...]
