Current Genetics recently published an article by Visiting Instructor of Biology Astrid H. Helfant titled, "Composition of the spindle pole body of Saccharomyces cerevisiae and the proteins involved in its duplication." 

In her review paper, Helfant focuses on the centrosome in the budding yeast Saccharomyces cerevisiae, referred to as the spindle pole body (SPB).  The centrosome is an organelle found in fungi (including yeast) and in most animal cells and is known to play a key role in maintaining the genomic stability of the cell. Upon its duplication, the centrosome forms a bipolar spindle responsible for separating the genomic DNA of a dividing cell. Helfant gives a comprehensive overview of  the genetic and biochemical  studies that have revealed the functional and physical relationships of the SPB (yeast centrosome) components and proteins important for SPB duplication. For more information on Helfant's research, follow the link: http://academics.hamilton.edu/biology/ahelfant/helfant_research_interests.html

Helfant will be teaching Biochemistry this fall (Bio346F) and Genes and Genomes (Bio248S) this coming spring semester.
