| Entry of all eukaryotic cells into M-phase of the cell cycle is regulated by activation of cdc2 kinase. Activation of cdc2 is controlled at several steps including cyclin B1 binding, phosphorylation of cdc2 at threonine 161, and dephosphorylation of cdc2 at Thr14/Tyr15 (1–5). The protein levels of cdk inhibitors and the cdk-associated cyclins are regulated by phosphorylation, ubiquitination and degradation allowing for a stoichiometric regulation of cell cycle events (6). Four cyclin B1 phosphorylation sites (Ser126, 128, 133 and 147) are located in the cytoplasmic retention signal (CRS) domain and are thought to regulate the translocation of cyclin B1 to the nucleus at the G2/M checkpoint (8–10). Phosphorylation of cyclin B1 has been shown to be required for cdc25C-dependent dephosphorylation of cdc2 Tyr15 and subsequent cdc2/cyclin B1 activation (11). While cdc2/cyclin B1 itself can phosphorylate Ser126 and Ser128, polo-like kinase 1 has been shown to phosphorylate cyclin B1 at Ser147 (8,12). | | | Catalog # | C8453-04A | | Applications | Suitable for use in Western Blot.
