Rotation projects are available to study chromatin structure and function. Project 1. Measure histone dynamics in yeast. Histone dynamics play major roles in chromatin metabolism and in the inheritance of chromatin states. To measure histone replacement rates in yeast, we have created yeast strains carrying inducible epitope-tagged histones H3 and H2A. Using microarrays, we will measure histone replacement rates in a variety of mutant yeast to ascertain the role of various chromatin remodeling factors in histone exchange reactions. Project 2. Characterize mechanisms for epigenetic inheritance in yeast. We have identified a variety of genes whose expression state in yeast is epigenetically heritable. We will screen the yeast genome for genes that affect the inheritance of these expression patterns. Project 3. Measure histone dynamics in embryonic stem cells. Embryonic stem cells are pluripotent cells that can give rise to every type of cell in the adult animal. The role of chromatin structure in maintaining this pluripotent state is poorly understood, but it appears that stem cell chromatin is exceptionally labile relative to that in differentiated cells. We will create stem cell lines with inducible tagged histones to measure histone replacement rates across the mouse genome.

Potential Rotation Projects <p >Research in the Munson lab is focused on biochemical/biophysical and cell biological characterization of proteins in the exocyst complex. Potential rotation projects include the following: Cloning of various exocyst protein domains and point mutations. These will be expressed in E. coli for biochemical/structural studies, and their functions tested in yeast. Protein expression and purification. Develop purification strategies for several exocyst proteins and their domains, using chromatography methods such as ion exchange and gel filtration (Fig. 2). Characterization of the purified exocyst proteins. Protein structure, stability, oligomerization state and protein:protein interactions will be monitored by such techniques as circular dichroism, analytical ultracentrifugation and gel filtration (Fig. 3). Crystallography. We have determined the structure of the C-terminal domain of Sec6p (Fig. 4). Crystallization trials ofotherexocyst proteins and their domains are in progress.

Potential Rotation Projects <p >Rotations are available in Dr. Rock’s laboratory for graduate students in the GSBS program. The rotation projects will explore various aspects of how the immune system carries out surveillance to detect viral infections and cancers. Among the potential areas of research are: (1) The alarm signals that alert the immune system to potential danger; (2) The initial innate immune and inflammatory response to infection or other dangerous situations; (3) The biology of the sentinel cells (e.g. dendritic cells) that sense danger and report it the adaptive immune system; (4) The mechanisms by which sentinel cells (e.g. dendritic cells) acquire and display antigens to T cells; and, (5) The antigen presentation pathways by which virally infected or cancer cells display a sampling of their expressed gene products to the activated T cells. Specific rotation projects are chosen based on the student’s interests and state/availability of the various projects in the laboratory. The goals of rotations are for the student to gain knowledge in immunology, to learn how to approach experimental problems, to learn new techniques and methods, and to actually generate data that moves our knowledge forward. In addition, the rotation provides the student the opportunity to evaluate the laboratory as a possible place to conduct their thesis research in the future.

Potential Rotation Projects Rotation projects in my laboratory will involve questions of how cilia are assembled and the function these organelles play in mammals. Projects vary depending on ongoing work in the laboratory and interests of the rotation student. Rotations in my laboratory can give students exposure to a range of techniques from mouse breeding and histological analysis of mouse tissues to mammalian cell culture and other cell biological techniques.
Rotation Projects Project #1: Signaling in the MAP kinase cascade. Membranerecruitment ofthe kinase cascade "scaffold" protein, Ste5, initiates signaling. But our recent work suggests that membrane localization alsoboosts signaling efficiency through the kinase cascade, and similar findings have been reported in a mammalian pathway. Yet the mechanism explaining this effect is unknown.This project would use molecular genetic approaches to probe thisphenomenon. Project #2: Membrane targeting domains. Our recent work identified a small membrane-binding domain that guides Ste5 to the plasma membrane, but it does so only acting in conjunction with protein-protein interactions. Relatedly, we have recently found similar domains, and their cooperative relationship with protein-protein interactions, in several other plasma membrane-localized signaling proteins. We suspect this may be a very common arrangement, and that multiple weak interactions are advantageous to ensuring dynamic localization that constantly probes the availability of membrane-localized binding partners. This project would involve conducting a small-scale survey of polarized proteins in yeast, searching for small membrane-binding domains that are critical for their normal localization and function.
Rotation Project Background
In yeast cells, protein translocation across the endoplasmic reticulum can occur by cotranslational or posttranslational pathways. The objective of this project is to develop a rapid method to inactivate the posttranslational pathway in vivo in yeast cells by appending the CMV-ribosome stalling sequence to the C-terminus of a typical posttranslational translocation substrate (carboxypeptidase Y). Complexes between the posttranslational translocation channel (SEC complex) and the stalled ribosomes will be purified for structural and functional analysis.
A postdoctoral position is available to study in this laboratory. Contact Dr. Craig for additional details.
Potential Rotation Projects Project #1: Lipid-Layer Protein Crystallization for Electron Microscopy.While individual protein molecules can be readily visualized by EM, structural information is greatly enhanced if the molecules can by crystallized into 2-dimensional ordered arrays. Methods for achieving this are well established, making use of lipid monolayers at an air-water interface. Follow literature methods to crystallize "standard" proteins using the lipid-layer method. Observe results by electron microscopy following negative staining. If time permits, carry out preliminary image processing of micrographs and/or crystallization of unknown proteins. Techniques to be learned: lipid layer crystallization methods; grid preparation; use of electron microscope; image processing.
Potential Rotation Projects Several rotation projects are available in structural biology of immune receptors, antigen presentation pathways, T-cell activation, and development of novel T-cell detection reagents. Please see Prof. Stern for details.
Joseph J. Byrne Chair in Biomedical Research
? Rotation Projects Multiple rotation projects are available in several areas related to long-range gene regulation and higher order chromosome organization. Projects include thorough analyses of the biochemical mechanisms of long-range gene regulation of specific disease-related genes, as well as large-scale analyses of chromosome organization using high-throughput genomics technologies (5C and Hi-C). The lab employs a wide range of experimental approaches, including cell culture, protein biochemistry, microscopy, genomics as well computational approaches such as bioinformatics and modeling. Specific rotation projects are determined dependent on the interest of the student.
Potential Rotation Projects <p >Our laboratory combines genetic and biochemical approaches to investigate the molecular underpinnings of adaptation. Potential rotation projects are available in two general (and partially overlapping) areas: exploring fitness landscapes through systematic approaches and investigating the molecular mechanism of the Hsp90 chaperone in signal transduction. Please contact the lab to discuss specific rotation projects in more detail.
Focus: The Munro laboratory develops and applies quantitative biophysical approaches to visualize virus replication, and probe the functions of the proteins and RNAs involved.
