General Information

Paragraph No	Gene Name	Paragraph Text
3	CDK1	Cyclin-dependent kinases (cdks) are a family of serine-threonine kinases that are involved in cell cycle control and cell division in eukaryotes. Cdks are catalytic subunits that are activated by association with proteins called cyclins, forming cyclin-cdk complexes. Cdk kinase activity is regulated by cyclin binding, phosphorylation and dephosphorylation, protein degradation, protein-protein interactions with cdk inhibitors, and subcellular localization.
4	CDK1	Tetrahymena thermophila Cdk1p shares homology with cdk homologs from other eukaryotes. It contains 11 catalytic domains characteristic of protein kinases, conserves all of the regulatory phosphorylation sites found in cdks, and has a slightly modified cyclin-binding PSTAIRE motif that is a hallmark of cdks. The Tetrahymena thermophila Cdk1p was also found to bind Saccharomyces cerevisiae p13suc1, a yeast cyclin.
5	CDK1	The level of Cdk1p fluctuates over the vegetative cell cycle, correlating with its histone H1 kinase activity. Cdk1p is associated with the basal bodies of the ciliary rows of the cell cortex and the oral apparatus. This localization, along with the phenotype of a partial CDK1 knockout phenotype of bent and buckled ciliary rows, suggests that Cdk1p is involved in cortical morphogenesis.
