Investigating the link between histone phosphorylation and yeast 14-3-3 proteins in programmed cell death

Objective

Post-translational modifications of histones including acetylation and methylation, serve as signals for various cellular processes, such as, transcription, DNA repair, and cell signalling. Histone phosphorylation has recently been connected to programmed cell death, also known as apoptosis, in both mammals and yeast.

Specifically, phosphorylation of serine 10 within histone H2B in the yeast S. cerevisiae has been linked to chromatin compaction during the late stages of apoptosis. Phosphorylation of this am ino acid residue is catalyzed by the yeast kinase Ste20. However, it still remains unknown how the activity of Ste20 towards H2B is controlled.

Interestingly, Ste20 has been shown to interact with the yeast 14-3-3 proteins, bmh1 and bmh2, which play a role in the regulation of histone phosphorylation. Based on these findings and the fact that mammalian 14-3-3 proteins are implicated in the apoptotic process, we hypothesize that the bmh proteins are involved in cell death by associating with phosphorylated histones.

The experiments outlined in this proposal are aimed to determine; 1) whether the bmh proteins have an apoptotic function in yeast, 2) whether the bmh proteins regulate the activity of Ste20, 3) whether the bmh proteins bind specifically to phosphorylated H2B-Ser10, and 4) whether induction of apoptosis affects the localization of bmh proteins.

These experiments should provide a better knowledge of the molecular mechanisms that underlie the apoptotic process. It is critical to understand these mechanisms because a defect in the apoptotic pathway can often lead to human proliferative diseases such as cancer.

Additionally, these studies will provide me with the opportunity to explore and learn to use yeast as an experimental model system. Most importantly, I will be exposed to new molecular approaches that will complement my existing scientific knowledge and thus, allow me to address crucial biological questions concerning chromatin structure in cells.
