How can you use “cak” in a sentence? Here are some example sentences to help you improve your vocabulary:

In the case of the Hint-homologous HNT1 gene of S. cerevisiae , the phenotype of the single mutant was mild and the biological pathway, positive regulation of Kin28, the yeast homolog of Cdk7, was revealed by synthetic lethal interactions between hnt1 and hypomorphic alleles of cak1 , kin28 , ccl1 and tfb3 [ 9 ] . Because backup systems to limit problems with hnt2 mutant cells apparently exist, synthetic lethal interactions may be critical to identify the Hnt2 biological pathway.
Recently, discovery that the Hint-homologous HNT1 gene is required for high temperature growth on galactose and observations that alleles of cak1 , kin28 , ccl1 and tfb3 are hypersensitive to loss of Hnt1 enzyme activity provided evidence that Hnt1 enzyme activity positively regulates Kin28 function, particularly on galactose media [ 9 ] . Though phenotypic consequences of hnt2 mutations have yet to be discovered, our observations suggest that synthetic lethal interactions with hnt2 mutations are likely to be found in adenine prototrophic strains undergoing heat shock.
Cdc37 also promotes the production of Cak1.
Loss of Hnt1 enzymatic activity also renders cells hypersensitive to mutations in the cyclin H homolog Ccl1, the MAT1 homolog Tfb3, and to Cak1, the activating kinase for Kin28, all of which lead to destabilized Kin28 complexes and a likely increase in concentration of Kin28 monomers [ 30].
Cak1 in yeast is the human homolog of CAK trimeric enzyme containing CDK7, cyclin H, and MAT1.
