The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
Cycle (cyc) is a gene in Drosophila melanogaster that encodes the CYCLE protein (CYC). The Cycle gene ( c yc) is expressed in a variety of cell types in a circadian manner. It is involved in controlling both the sleep-wake cycle and circadian regulation of gene expression by promoting transcription in a negative feedback mechanism.
Cell division cycle 7-related protein kinase is an enzyme that in humans is encoded by the CDC7 gene. [5] [6] [7] The Cdc7 kinase is involved in regulation of the cell cycle at the point of chromosomal DNA replication. [8] The gene CDC7 appears to be conserved throughout eukaryotic evolution; this means that most eukaryotic cells have the Cdc7 ...
Cdk5 is a proline-directed serine/threonine kinase, which was first identified as a CDK family member due to its similar structure to CDC2/CDK1 in humans, a protein that plays a crucial role in the regulation of the cell cycle. The gene Cdk5 contains 12 exons in a region that contains around 5000 nucleotides (5kb), as it was determined by ...

TGF-𝝱 works by binding to cell-surface receptors and activating the Smad gene regulatory proteins. Smad proteins then trigger an increase in p15, which inhibits cyclin D1 and prevents cell cycle progression. In many cancers, there is a loss-of-function mutation in the Smad proteins, thus negating the entire anti-mitogenic pathway. [5]

Two checkpoint kinase subtypes have been identified, Chk1 and Chk2. Chk1 is a central component of genome surveillance pathways and is a key regulator of the cell cycle and cell survival. Chk1 is required for the initiation of DNA damage checkpoints and has recently been shown to play a role in the normal (unperturbed) cell cycle. [9]
