From Cdc2 to Cdk1
The two major processes common to all cell cycles are S phase, when chromosomes are replicated, and M phase, when the replicated chromosomes are segregated into two daughter cells. In most cell cycles, an interval of time, G1 phase, separates the previous cell division from the beginning of the next S phase. It is now firmly established that progression of the cell cycle – that is, transitions ...
متن کاملHuman p53 is phosphorylated by p60-cdc2 and cyclin B-cdc2.
The human anti-oncoprotein p53 is shown to be a substrate of cdc2. The primary site of phosphorylation is serine-315. Serine-315 is phosphorylated by both p60-cdc2 and cyclin B-cdc2 enzymes. The phosphorylation of p53 is cell cycle-dependent. The abundance of p53 also oscillates during the cell cycle. The protein is largely absent from cells that have just completed division but accumulates in ...
متن کاملNeuronal cdc2-like kinase: a cdc2-related protein kinase with predominantly neuronal expression.
Recent studies have shown that there exists a family of protein kinases structurally and functionally related to the yeast cell cycle regulatory kinase cdc2 [Meyerson, M., Faha, B., Su, L.-K., Harlow, E. & Tsai, L.-H. (1991) Cold Spring Harbor Symp. Quant. Biol. 56, 177-186 and Meyerson, M., Enders, G. H., Wu, C.-L., Su, L.-K., Gorka, C., Nelson, C., Harlow, E. & Tsai, L.-H. (1992) EMBO J. 11, ...
متن کاملInhibition of cdc2 activation by INH/PP2A.
INH, a type 2A protein phosphatase (PP2A), negatively regulates entry into M phase and the cyclin B-dependent activation of cdc2 in Xenopus extracts. INH appears to be central to the mechanism of the trigger for mitotic initiation, as it prevents the premature activation of cdc2. We first show that INH is a conventional form of PP2A with a B alpha regulatory subunit. We next explore the mechani...
متن کاملRaptor is Phosphorylated by cdc2 during Mitosis
BACKGROUND The appropriate control of mitotic entry and exit is reliant on a series of interlocking signaling events that coordinately drive the biological processes required for accurate cell division. Overlaid onto these signals that promote orchestrated cell division are checkpoints that ensure appropriate mitotic spindle formation, a lack of DNA damage, kinetochore attachment, and that each...
