Mast1,2, Song Li1, John D. Aitchison1,2 1Institute for Systems Biology, 2Center for Infectious Disease Research We present a method for quantifying growth phenotypes of individual yeast cells as they grow into colonies on solid media using time-lapse microscopy termed, One-cell Doubling Evaluation of Living Arrays of Yeast (ODELAY). Population heterogeneity of genetically identical cells growing into colonies can be directly observed and quantified. Immunology and Infection Peptide-based Identification of Functional Motifs and their Binding Partners Martin N. Shelton1,2, Ming Bo Huang1, Syed Ali1,3, Kateena Johnson1, William Roth1, Michael Powell1, Vincent Bond1 1Department of Microbiology, Biochemistry, & Immunology, Morehouse School of Medicine, 2Institute for Systems Biology, 3Advanced Medical & Dental Institute, Universiti Sains Malaysia Techniques to dissect the mechanisms underlying the secretion of HIV-1 Nef in exosomes are described. Specific short peptides derived from Nef and protein transfection were exploited to determine the structure, function, and binding partners of Nef’s Secretion Modification Region. These procedures have general relevance in many mechanistic studies. Biology Quantitative Phosphoproteomics in Fatty Acid Stimulated Saccharomyces cerevisiae Ramsey A. Saleem1, John D. Aitchison1 1Institute for Systems Biology Description of a quantitative phosphorylation procedure using cryolysis, urea solubilziation, HILIC fractionation and IMAC enrichment of phosphorylated peptides.
