Cyclin-dependent kinase 1; Plays a key role in the control of the eukaryotic cell cycle. It is required in higher cells for entry into S-phase and mitosis. p34 is a component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II (By similarity).

G2/mitotic-specific cyclin-B1; Essential for the control of the cell cycle at the G2/M (mitosis) transition; Belongs to the cyclin family. Cyclin AB subfamily.

Membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase wee-1.1; Acts as a negative regulator of entry into mitosis (G2 to M transition) by phosphorylation of the CDK1 kinase; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WEE1 subfamily.

G2/mitotic-specific cyclin-B3; Could be involved at the G2/M (mitosis) transition (Probable). Interacts with the CDK1 and CDK2 protein kinases (Probable). G2/M cyclins accumulate steadily during G2 and are abruptly destroyed at mitosis (Probable). Plays a role during oocyte meiosis II.

G2/mitotic-specific cyclin-A1; Involved in the control of the cell cycle after S phase. May bind to and activate cdk-1 and/or cdk-2 to promote cell cycle progression. Necessary for embryogenesis. Belongs to the cyclin family. Cyclin AB subfamily.

Serine/threonine-protein kinase chk-1; 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. Required for checkpoint mediated cell cycle arrest in response to DNA damage in germline cells. Delays cell-cycle reentry of the Z2 and Z3 primordial germ cells in response to transcription-induced DNA damage as they emerge from cell cycle arrest in L1 larvae. Essential for embryogene [...]

Cyclin-dependent kinase 2; Serine/threonine-protein kinase which, in association with cye-1, regulates proliferation, quiescent state and cell fate during the development of several cell lineages. . In the embryo, initiates the establishment of cell polarity through the recruitment of the centrosomal proteins spd-2 and spd-5 during prophase. Phosphorylation and inhibition of the translational repressor gld-1 by the cdk-2/cye-1 complex regulates the pool of germline stem cells and the size of the mitotic zone in the gonads by preventing entry into meiosis.

F-box/WD repeat-containing protein lin-23; Functions cell autonomously to negatively regulate cell cycle progression. Required to restrain cell proliferation in response to developmental cues. Probably recognizes and binds to some proteins and promotes their ubiquitination and degradation (By similarity).

Serine/threonine-protein kinase plk-2; Serine/threonine-protein kinase which plays a role, during oogenesis, in chromosome pairing and synapsis, by facilitating the recruitment and attachment of meiotic chromosomes to the nuclear envelope during prophase. Regulates the formation of sun-1 patches along the nuclear envelope. Promotes meiotic nuclei apoptosis in response to chromosomal asynapsis. Plays a redundant role with plk-1 in the establishment of cell polarity downstream of mex-5 and mex-6 during the first embryonic cell divisions. Plays a role in nicotinic acetylcholine receptor- [...]
