Treatment of S2-derived S2-NP cells with dsRNA made from templates generated with primers directed against cdc2 results in a decrease in Stat92E tyrosine phosphorylation.
When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, an increase in the proportion of G2/M phase cells, a decrease in cell size, a decrease in cytokinetic index, a decrease in the ratio of cells in prometaphase and metaphase versus the total number of mitotic cells and chromosome abnormalities are seen.
RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in Kc167 and S2R+ cells: cell size is increased, microtubules are uniform or disorganised, cell shape is irregular, and cell number is decreased indicative of a failure in cell cycle progression through G1 to S and G2 to M stages.
By attenuating cdc2 function without blocking mitosis, normally asymmetric neural progenitor divisions become defective, failing to correctly localise asymmetric components during mitosis and/or to resolve distinct sibling fates.
A cdc2-dependent checkpoint acts to maintain diplody. In G2, esg is required to maintain a high level of G2/M cdk (a complex that includes the catalytic subunit encoded by cdc2 and a regulatory subunit G2 cyclin) that actively inhibits the entry into S phase.
Mutations in fzy result in metaphase arrest, neither CycA, CycB or CycB3 are degraded in this arrest. Inactivation of a temperature sensitive cdc2 in fzy metaphase arrest causes a reversion to interphase morphology. This reversion is not accompanied by completion of mitosis so there is no increase in anaphase cells or change in cell number or size.
During development changing levels of cell cycle regulators alters the rate limiting step and the mechanism governing progress of the cell cycle. Three phases of developmental progression of cell cycle regulation have been defined. The first seven cycles run in the presence of constitutively active cdc2. Later during cycles 8-13 increasing mitotic destruction of cyclins drives oscillations in cdc2 activity, cyclin accumulation becomes the rate limiting step for mitosis. Degradation of maternally supplied stg causes tyrosine dephosphorylation of cdc2 to become rate limiting for mitosis beginning in cycle 14.
Yeast interaction mating has been used to characterise Cyclin-dependent kinase interactor proteins (the prey) in hunts with either cdc2 or cdc2c as baits.
In contrast to the polo gene product, for which kinase activity peaks cyclically at late anaphase/telophase, CycB-associated cdc2 histone H1 kinase activity is maximal upon entry into mitosis during the rapid syncytial mitoses.
cdc2 function is essential for cell proliferation throughout development, though block occurs in G2 and no function in S phase could be identified. While the mitotic proliferation of imaginal cells was blocked in mutants, non-imaginal cells continue to grow and endoreplicate their DNA. cdc2c cannot compensate for lack of cdc2 function indicating the independence of their action.
Recombination mapping and intensive mapping studies of the Su(var)207 and Su(var)2-1216 chromosomes suggested a closely linked second site lethal. Genetic and molecular analysis of the second site lethal revealed it to be an allele of the cdc2 gene (Lehner, EMBO J. 9: 3573--3581, Jimenez, EMBO J. 9: 3565--3571).
Northern blot and in situ hybridization studies demonstrate that cdc2 and cdc2c are co-expressed during embryogenesis. cdc2 expression is correlated with cell proliferation.
