    basic FUNCTION
  • directly regulates microtubule dynamics at mitosis through phosphorylation of MAP4 (
  • cdc2-mediated phosphorylation is an important regulator of nestin organization and dynamics during mitosis (
  • acting as an histone 1-kinase (H1K)
  • involved in cell cycle regulation (G1 to S and G2 to M transition)
  • phosphorylating JUNB and lowering its level in mitotic and early G1 cells
  • putative upregulated c-Myc target gene
  • G2 phase CCNA1/CDK2 controls the timing of entry into mitosis by controlling the subsequent activation of CCNB/CDK1, but also has an unexpected role in coordinating the activation of CCNB/CDK1 at the centrosome and in the nucleus
  • is the only essential cell cycle CDK (in the absence of interphase Cdks, CDC2 can execute all the events that are required to drive cell division)
  • can activate CDC25C
  • phosphorylates ELAVL1 during G2, thereby helping to retain it in the nucleus in association with 14-3-3 and hindering its post-transcriptional function and anti-apoptotic influence
  • essential for DNA replication downstream formation of replication initiation complexes in hepatocytes but not in fibroblasts
  • involved in CDK1 and CDK2-mediated phosphorylation, a key mechanism governing EZH2 function
  • promote interphase nuclear pore complexes formation in human dividing cells
  • with AURKA and PLK1, participate in a feedback activation loop and activation of CDK1 initiates the feedback loop activity, leading to rapid and timely entry into mitosis
  • implicated in phosphorylation of CHEK1 which participates in cytoplasmic sequestration of CHEK1 activity
  • CDK1, CDK2, CDK5, can phosphorylate human DNMT1 at Ser154, suggesting an important role for CDKs in controlling DNA methylation patterns in mammalian cells
  • robust timing and ordering of cell cycle events depend on gradual changes in the substrate specificity of CDK1
  • CDK1 and AURKB cooperatively modulate microtubule dynamics and AURKB-dependent phosphorylation of INCENP controls spindle function by excluding the CPC from spindle regions engaged in microtubule polymerization
  • permits resection by phosphorylation of RBBP8 but also prevents RAD51 binding to the resected ends during M-phase double-strand break repair
  • is a critical regulator of DSB repair in M phase
  • archetypical kinase and a central regulator that drives cells through G2 phase and mitosis
  • essential for cell proliferation and tumorigenesis, it is not required for DNA replication and liver regeneration
  • is redundant for S phase progression, but its loss results in endoreduplication
  • slow increase in CDK1 activity in meiosis I acts as a timing mechanism to allow stable kinetochore-microtubule (K-MT) attachments only after bipolar spindle formation, thus preventing attachment errors
  • activity of CDK1 and PLK1 allows spatiotemporally controlled suppression of TP53BP1 function during mitosis
  • CDK1 is a novel NFAT protein kinase that negatively regulates osteoclast differentiation

  • separase (
  • inactivation of EEF2K by CDK1 may serve to keep EEF2 active during mitosis (where calcium levels rise) and thereby permit protein synthesis to proceed in mitotic cells
  • CDK1 bind to RALBP1 during mitosis, such that endocytosis is inhibited (increased expression of CDK1 inhibits transport function of RALBP1 and promotes apoptosis)
  • different levels of CCNB1-CDK1 kinase activity trigger different mitotic events, thus revealing how the remarkable reorganization of the cell is coordinated at mitotic entry
  • KMT2E is a novel cellular target of CDK1, and the phosphorylation of KMT2E may have an indispensable role in the mitotic progression
  • combined action of CDK1, NEK6, NEK7, and likely other kinases contributes to hyperphosphorylation of NUP98 during mitosis (
  • CEP63 binds to and recruits CDK1 to centrosomes, and thereby regulates mitotic entry (
  • positive feedback in Cdk1 activation serves to overcome the activity of Cdk-opposing phosphatases and thus sustains forward progression in mitosis (
  • initial phase of chromosome condensation requires CDK1-mediated phosphorylation of the NCAPD3 subunit of condensin II
  • CDK1/CCNB1-dependent hyper-phosphorylation of BCL2L11 during prolonged mitotic arrest is an important cell death signal
  • as cells progress through S phase, CCNA2 initially forms complexes with CDK2, and, later, most CCNA2 molecules are bound to CDK1
  • PBK act as a substrate for CDK1
  • during mitosis the kinetochore (KT)-microtubule (MT)-associated protein CLASP2 is progressively and distinctively phosphorylated by CDK1 and PLK1 kinases, concomitant with the establishment of KT-MT attachments
  • CDK1 and POU5F1 interplay to inhibit ES cell differentiation into trophectoderm and thereby maintain stemness

  • PIN1 interacts with SEPT9 upon mitotic phosphorylation at Thr-24 by CDK1

  • VGLL4 is phosphorylated by CDK1 during antimitotic drug-induced mitotic arrest and also in normal mitosis
