Membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase wee-1.3; Acts as a negative regulator of entry into mitosis (G2 to M transition) by phosphorylation of the CDK1 kinase during oocyte maturation. Required for oocyte maturation, embryonic development, germline proliferation and initiation of meiosis during spermatogenesis. Required for chromosome structure during mitosis and negative regulation of nuclear envelope breakdown. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WEE1 subfamily.

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.

Cyclin N-terminal domain-containing protein; Belongs to the cyclin family.

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).

Cyclin N-terminal domain-containing protein; Belongs to the cyclin family.

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.

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.

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 [...]
