CDK1/CDC2-cyclin-B controls pronuclear union in interphase fertilized eggs. Essential for early stages of embryonic development. During G2 and early mitosis, CDC25A/B/C-mediated dephosphorylation activates CDK1/cyclin complexes which phosphorylate several substrates that trigger at least centrosome separation, Golgi dynamics, nuclear envelope breakdown and chromosome condensation. Once chromosomes are condensed and aligned at the metaphase plate, CDK1 activity is switched off by WEE1- and PKMYT1-mediated phosphorylation to allow sister chromatid separation, chromosome decondensation, reformation of the nuclear envelope and cytokinesis. Inactivated by PKR/EIF2AK2- and WEE1-mediated phosphorylation upon DNA damage to stop cell cycle and genome replication at the G2 checkpoint thus facilitating DNA repair. Reactivated after successful DNA repair through WIP1-dependent signaling leading to CDC25A/B/C-mediated dephosphorylation and restoring cell cycle progression. In proliferating cells, CDK1-mediated FOXO1 phosphorylation at the G2-M phase represses FOXO1 interaction with 14-3-3 proteins and thereby promotes FOXO1 nuclear accumulation and transcription factor activity, leading to cell death of postmitotic neurons. The phosphorylation of beta-tubulins regulates microtubule dynamics during mitosis. NEDD1 phosphorylation promotes PLK1-mediated NEDD1 phosphorylation and subsequent targeting of the gamma-tubulin ring complex (gTuRC) to the centrosome, an important step for spindle formation. In addition, CC2D1A phosphorylation regulates CC2D1A spindle pole localization and association with SCC1/RAD21 and centriole cohesion during mitosis. The phosphorylation of Bcl-xL/BCL2L1 after prolongated G2 arrest upon DNA damage triggers apoptosis. In contrast, CASP8 phosphorylation during mitosis prevents its activation by proteolysis and subsequent apoptosis. This phosphorylation occurs in cancer cell lines, as well as in primary breast tissues and lymphocytes. EZH2 phosphorylation promotes H3K27me3 maintenance and epigenetic gene silencing. CALD1 phosphorylation promotes Schwann cell migration during peripheral nerve regeneration. CDK1-cyclin-B complex phosphorylates NCKAP5L and mediates its dissociation from centrosomes during mitosis (PubMed:26549230). Regulates the amplitude of the cyclic expression of the core clock gene ARNTL/BMAL1 by phosphorylating its transcriptional repressor NR1D1, and this phosphorylation is necessary for SCF(FBXW7)-mediated ubiquitination and proteasomal degradation of NR1D1 (PubMed:27238018).FUNCTION (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) in hepatocytes and facilitates its cell entry.ACTIVITY REGULATION Phosphorylation at Thr-14 or Tyr-15 inactivates the enzyme, while phosphorylation at Thr-161 activates it. Activated through a multistep process; binding to cyclin-B is required for relocation of cyclin-kinase complexes to the nucleus, activated by CAK/CDK7-mediated phosphorylation on Thr-161, and CDC25-mediated dephosphorylation of inhibitory phosphorylation on Thr-14 and Tyr-15. Inhibited by flavopiridol and derivatives, pyrimidine derivatives, pyridine derivatives, purine derivatives, staurosporine, paullones, oxoindoles, indazole analogs, indolin-2-ones, pyrazolo[3,4-b]pyridines, imidazo[1,2-a]pyridine (AZ703), thiazolinone analogs(RO-3306), thiazol urea, macrocyclic quinoxalin-2-one, pyrrolo[2,3-a]carbazole, pyrazolo[1,5-a]-1,3,5-triazine, pyrazolo[1,5-a]pyrimidine (Dinaciclib, SCH 727965), 2-(1-ethyl-2-hydroxyethylamino)-6-benzylamino-9-isopropylpurine (roscovitine), olomoucine, AG-024322, AT-7519, P276-00, R547/Ro-4584820 and SNS-032/BMS-387032. Repressed by the CDK inhibitors CDKN1A/p21 and CDKN1B/p27 during the G1 phase and by CDKN1A/p21 at the G1-S checkpoint upon DNA damage. Transient activation by rapid and transient dephosphorylation at Tyr-15 triggered by TGFB1.SUBUNIT Forms a stable but non-covalent complex with a regulatory subunit and with a cyclin. Interacts with cyclins-B (CCNB1, CCNB2 and CCNB3) to form a serine/threonine kinase holoenzyme complex also known as maturation promoting factor (MPF). The cyclin subunit imparts substrate specificity to the complex. Can also form CDK1-cylin-D and CDK1-cyclin-E complexes that phosphorylate RB1 in vitro. Binds to RB1 and other transcription factors such as FOXO1 and RUNX2. Promotes G2-M transition when in complex with a cyclin-B. Interacts with DLGAP5. Binds to the CDK inhibitors CDKN1A/p21 and CDKN1B/p27. Isoform 2 is unable to complex with cyclin-B1 and also fails to bind to CDKN1A/p21. Interacts with catalytically active CCNB1 and RALBP1 during mitosis to form an endocytotic complex during interphase. Associates with cyclins-A and B1 during S-phase in regenerating hepatocytes. Interacts with FANCC. Interacts with CEP63; this interaction recruits CDK1 to centrosomes. Interacts with CENPA (PubMed:25556658). Interacts with NR1D1 (PubMed:27238018). Interacts with proteasome subunit PSMA8; to participate in meiosis progression during spermatogenesis (By similarity).TISSUE SPECIFICITY Isoform 2 is found in breast cancer tissues.INDUCTION Follows a cyclic expression; during interphase, accumulates gradually following G1, S to reach a critical threshold at the end of G2, which promotes self-activation and triggers onset of mitosis. Induced transiently by TGFB1 at an early phase of TGFB1-mediated apoptosis, but later repressed. Triggered by CKS1B during mitotic entry in breast cancer cells. Down-regulated under genotoxic stresses triggered by PKR/EIF2AK2-mediated phosphorylation.PTM Phosphorylation at Thr-161 by CAK/CDK7 activates kinase activity. Phosphorylation at Thr-14 and Tyr-15 by PKMYT1 prevents nuclear translocation. Phosphorylation at Tyr-15 by WEE1 and WEE2 inhibits the protein kinase activity and acts as a negative regulator of entry into mitosis (G2 to M transition). Phosphorylation by PKMYT1 and WEE1 takes place during mitosis to keep CDK1-cyclin-B complexes inactive until the end of G2. By the end of G2, PKMYT1 and WEE1 are inactivated, but CDC25A and CDC25B are activated. Dephosphorylation by active CDC25A and CDC25B at Thr-14 and Tyr-15, leads to CDK1 activation at the G2-M transition. Phosphorylation at Tyr-15 by WEE2 during oogenesis is required to maintain meiotic arrest in oocytes during the germinal vesicle (GV) stage, a long period of quiescence at dictyate prophase I, leading to prevent meiotic reentry. Phosphorylation by WEE2 is also required for metaphase II exit during egg activation to ensure exit from meiosis in oocytes and promote pronuclear formation. Phosphorylated at Tyr-4 by PKR/EIF2AK2 upon genotoxic stress. This phosphorylation triggers CDK1 polyubiquitination and subsequent proteolysis, thus leading to G2 arrest. In response to UV irradiation, phosphorylation at Tyr-15 by PRKCD activates the G2/M DNA damage checkpoint.PTM Polyubiquitinated upon genotoxic stress.MISCELLANEOUS As a key regulator of the cell cycle, CDK1 is a potent therapeutic target for inhibitors in cancer treatment.SIMILARITY Belongs to the protein kinase superfamily.

Is regulated by MAD2L1: in metaphase the MAD2L1-CDC20-APC/C ternary complex is inactive and in anaphase the CDC20-APC/C binary complex is active in degrading substrates. The CDC20-APC/C complex positively regulates the formation of synaptic vesicle clustering at active zone to the presynaptic membrane in postmitotic neurons. CDC20-APC/C-induced degradation of NEUROD2 induces presynaptic differentiation.PATHWAY Protein modification; protein ubiquitination.SUBUNIT Found in a complex with CDC20, CDC27, SPATC1 and TUBG1.

Interacts with CDK5RAP2 and SIRT2. Interacts with isoform 1 of NEK2. Interacts with HSF1 (via phosphorylated form); this interaction occurs in mitosis in a MAD2L1-dependent manner and prevents PLK1-stimulated degradation of HSF1 by blocking the recruitment of the SCF(BTRC) ubiquitin ligase complex (PubMed:18794143).

Phosphorylated by NEK2.PTM Dephosphorylated by CTDP1.PTM Ubiquitinated and degraded by the proteasome during spindle assembly checkpoint. Deubiquitinated by USP44, leading to stabilize the MAD2L1-CDC20-APC/C ternary complex, thereby preventing premature activation of the APC/C. Ubiquitinated at Lys-490 during prometaphase.
