High impact information on CCNB3


Biological context of CCNB3

  • This may suggest a dominant-negative function of human cyclin B3 in competition with activating cyclins in G(0) and the G(1) phase of the cell cycle [3].
  • In order to determine whether downregulation of cyclin B3 at zygotene-pachytene transition was important for normal spermatogenesis, we investigated the consequences of expressing H. sapiens cyclin B3 after zygotene in mouse testes [4].

Physical interactions of CCNB3

  • It had been shown that cyclin B3 coimmunoprecipitates with cdk2; but this complex does not exhibit any kinase activity [3].
