High impact information on CCNA2

  • Mutation of the activating transcription factor (ATF) consensus sequence at bp -80 to -73 of the cyclin A promoter decreased its activity, indicating the critical role of the ATF site [1].
  • Cyclin A2 levels were higher in neonatal versus adult WT or transgenic mouse aortas [2].
  • We also demonstrate that deletion of, or point mutations, in the cyclin A homologue of the 10-residue "destruction box," previously described in cyclin B (Glotzer et al., 1991) abolish cyclin proteolysis at the transition from M-phase to interphase [3].
  • In addition, we find that E1 shuttling occurs in S phase, when cyclin A-Cdk2 is activated [4].
  • Notably, doxazosin inhibited phosphorylation of Rb and expression of cyclin A, both of which are necessary for cell cycle progression [5].
 

Anatomical context of CCNA2

  • Functionally novel tumor necrosis factor-alpha-modulated CHR-binding protein mediates cyclin A transcriptional repression in vascular endothelial cells [6].
 

Other interactions of CCNA2

  • An inconstant elongation of the poly(A) tail was observed for cyclin A2 transcripts after maturation, while a constant lengthening was observed for cyclin B1, occurring during the first 12 hr of incubation [7].
  • Expression of cell cycle associated proteins cyclin A, CDK-2, p27kip1 and p53 in equine sarcoids [8].
 

Analytical, diagnostic and therapeutic context of CCNA2

  • The binding of cyclin A to p34cdc2 and p32cdk2 and the protein kinase activity of the complexes has been measured by cell-free translation of the corresponding mRNA in extracts of frog eggs, followed by immunoprecipitation [3].
