Role Of Sumoylation In Mitochondrial Division In Tetrahymena Thermophila, Ramya Modi, James Forney

The Summer Undergraduate Research Fellowship (SURF) Symposium

SUMOylation is a post translation modification that involves the addition of a small protein called SUMO, Small Ubiquitin-like MOdifier to a target protein. It is an important mechanism for the regulation of gene expression, the maintenance of genomic stability and in modifying nuclear proteins. More recently evidence has emerged for its importance in regulating mitochondrial fission and fusion in mammalian cells. This study evaluates the parameters for optimal staining of Tetrahymena thermophila mitochondria using two different dyes and then examines different cell lines with defects in the SUMOylation pathway. The first staining method uses Mitotracker Green, a vital stain that …
