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.
Gene Set Association Analysis for RNA-Seq GSAASeq are computational methods that assess the differential expression of a pathway/gene set between two biological states based on sequence count data. GeneSCF a real-time based functional enrichment tool with support for multiple organisms.
CHEK2 regulates cell cycle progression and spindle assembly during mouse oocyte maturation and early embryo development. [ 13 ] [ 14 ] Although CHEK2 is a down stream effector of the ATM kinase that responds primarily to double-strand breaks it can also be activated by ATR (ataxia-telangiectasia and Rad3 related) kinase that responds primarily ...
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.
Fig. 1 The diagram shows the role of Cdk1 in progression through the S. cerevisiae cell cycle. Cln3-Cdk1 leads to Cln1,2-Cdk1 activity, eventually resulting in Clb5,6-Cdk1 activity and then Clb1-4-Cdk1 activity. [5] When bound to its cyclin partners, Cdk1 phosphorylation leads to cell cycle progression.
The CDK4 gene is located on chromosome 12 in humans. [7] The gene is composed of 4,583 base pairs which together code for the 303 amino acid protein with a molecular mass of 33,730 Da. [7] [8] All CDK proteins, including CDK4, have two lobes: the smaller N-terminal lobe (which contains an inhibitory G-loop), and the C terminal lobe (which contains an activation domain and a T-loop).
The cell division cycle protein 20 homolog is an essential regulator of cell division that is encoded by the CDC20 gene [5] [6] in humans. To the best of current knowledge its most important function is to activate the anaphase promoting complex (APC/C), a large 11-13 subunit complex that initiates chromatid separation and entrance into anaphase .
The murine double minute (mdm2) oncogene, which codes for the Mdm2 protein, was originally cloned, along with two other genes (mdm1 and mdm3) from the transformed mouse cell line 3T3-DM. Mdm2 overexpression, in cooperation with oncogenic Ras , promotes transformation of primary rodent fibroblasts, and mdm2 expression led to tumor formation in ...
