However, additional data are clearly needed to further investigate the roles of calpain proteolysis and proteasome-mediated proteolysis on chromosome segregation as well as the numerous other potential molecular mechanisms of aneuploidy.
Nonetheless, E2F is inactivated and/or downregulated upon progression to S phase, a regulatory feature that appears critical as E2F overexpression or ectopic activation induces apoptosis both in mammalian cells and in flies [ 12 ] [ 13 ] [ 14 ] [ 15 ] . Inactivation of the DNA-binding activity of E2F-1 by the cyclin A/Cdk complex has been shown to be critical for proper S phase progression [ 16 ] . In mammalian cells, E2F-1 is also subject to proteasome-mediated degradation [ 17 ] [ 18 ] [ 19 ] and recent evidence indicates that E2F-1 degradation occurs in S phase [ 20 ] . Control of E2F-1 stability has also been linked to its association with the F-box protein Skp2 [ 20 ] but this has not been tied to a specific phase of the cell cycle.
During this transition, tightly-regulated post-translational phosphorylation-dephosphorylation events and proteasome-mediated proteolytic reactions regulate the activation and inactivation of signal transduction pathways that control chromatin condensation, nuclear membrane dissolution, microtubule nucleation, and formation of a haploid oocyte [ 8 9 10 ] . Several kinases that exert major roles during OM include maturation promoting factor (MPF) [ 9 11 ] , mitogen-activated protein kinases (MAPKs) [ 12 13 ] , and the product of the c-mos protooncogene Mos kinase [ 14 15 ] . Also, during OM oocytes undergo two highly-regulated metaphase-anaphase transitions (MAT) in which homologous chromosomes are equally and randomly segregated to an oocyte and first polar body and a subsequent division in which equational division of sister chromatids results in a haploid oocyte and a second polar body.
Functional characterization of the interaction between Smad1, Az and HsN3 in the signaling pathways of BMPs led us to find a novel functional link between Smad1 and proteasome-mediated degradation events, through which a novel CBP/p300 repressor, SNIP1 [ 25 ] , is removed to allow the transcriptional activation of BMP-responsive genes.
The isolation of Smad1 interacting proteins reveals a physical interaction between Smad1 and components in proteasome-mediated degradation pathways
