Phenotypes of Saccharomyces cerevisiae cells lacking Isw2 chromatin remodelling factor
Frýdlová, Ivana ; Hašek, Jiří (advisor) ; Janderová, Blanka (referee) ; Sychrová, Hana (referee)
8 SUMMARY nd invasive growth. We showed that this phenotype is caused by de-repression that ncentrations of pheromone. Detailed analysis however uncovered some differences birth scar, rea that is commonly prohibited for budding. Based on our microarray data and double eletion mutant analyses, we identified one gene that is responsible for this phenotype. w2Δ cells as well as rth-scar phenotype as well as CWI pathway activation. These data prove, that de-regulation of expression of the daughter cell-specific gene DSE1 is The non-essential Saccharomyces cerevisiae protein Isw2 is a subunit of the ATP- dependent chromatin remodelling complex Isw2 that regulates the structure of chromatin, and thus plays an important role in regulation of transcription. Absence of the Isw2p induces the α-mating type-specific aberrant "shmoo-like" morphology a of a-specific genes in MATα cells and production of inappropriate a-factor which in turn activates the pheromone response pathway of isw2Δ MATα cells. Our results showed isw2Δ MATα cells can express the MATa-specific genes at the level which enables them to mate with other MATα cells. Invasion of isw2Δ MATα cells depends neither on the cell surface protein Flo11, nor on the invasive growth-specific transcription factor Tec1. On the other hand it requires components of the...
