James Haber. Broken chromosomes must be repaired if a cell is to survive; consequently cells have evolved a variety of mechanisms to repair double-strand breaks (DSBs). Memisoglu G, Eapen VV, Yang Y, Klionsky DJ, Haber JE. Saponaro M, Callahan D, Zheng X, Krejci L, Haber JE, Klein HL, Liberi G. Mad2 prolongs DNA damage checkpoint arrest caused by a double-strand break via a centromere-dependent mechanism. Systematic triple-mutant analysis uncovers functional connectivity between pathways involved in chromosome regulation. Lee CS, Lee K, Legube G, Haber JE. Some of these mutants prevent the cell from turning off the checkpoint (for example defects in two phosphatases that have to revers the phosphorylations imposed by checkpoint protein kinases).

Phosphorylation of Slx4 by Mec1 and Tel1 regulates the single-strand annealing mode of DNA repair in budding yeast. Chromosome breakage and repair. Regulation of budding yeast mating-type switching donor preference by the FHA domain of Fkh1. Abstract. We are interested in determining what are the specific biochemical roles played by the many proteins implicated in DNA recombination, repair and replication. The registration fee is $10. Daniel Laverty (Nagel Lab, HSPH): Novel Regulators of Double Strand Break Repair and Translesion Synthesis. B.A., Biochemistry, Brandeis University, Advisor: Dr. James Haber Here a DSB at the MAT locus is created by a site specific HO endonuclease, which we can induce synchronously in a large population of cells. We have been studying the phenomenon of adaptation, where cells that have an unrepaired (and unrepairable) DSB will eventually escape from the G2/M DNA damage arrest checkpoint and resume growth, despite the continued presence of the broken chromosome. Break-induced DNA replication. We have recently shown that RE directly interacts with the site of a DSB, and that in so doing it pulls HML close to the break.

We are also interested in gene targeting methods and in figuring out why these types of gene replacement and modification are quite inefficient, even in yeast. Li J, Coïc E, Lee K, Lee CS, Kim JA, Wu Q, Haber JE. As Research Coordinator in the Gluck lab, I am responsible for the compliance of all documentation regarding human subject testing. Victoria Sanchez Student at Brandeis University Greater Boston. We have shown that this regulation involves the action of a small Recombination Enhancer (RE) sequence that enables a donor on the left chromosome arm to recombine preferentially in MATa cells. I graduated from Brandeis University with a Bachelor's in … 37 Full PDFs related to this paper. This element is turned off in MAT cells, so the HMR donor on the right is preferred. (2013).

In addition cells have evolved a damage-sensing checkpoint system whereby the cells delay entry into mitosis until the break has been repaired. (2014). Finally we are interested in comparing how recombination occurs in mitosis and in meiosis. Download. Fast live simultaneous multiwavelength four-dimensional optical microscopy. One interesting class appears to enhance the cytoplasmic degradation of normally nuclear proteins by autophagy. Some mutants appear to enhance end-resection and generate more signal. Laboratory of Molecular Genetics Staff Scientist Dmitry Gordenin, Ph.D., sponsored Haber… On one hand, I was able to start a research project from scratch We are interested in understanding at the molecular level how recombination occurs and what roles are played by the many proteins involved in DNA recombination, repair and replication. Chromosome-refolding model of mating-type switching in yeast. Recombination between homologous sequences is a fundamentally important process both in meiosis and in mitotic cells. To this end we have expressed the site-specific HO endonuclease in meiotic cells so that we can compare recombination events at the same loci where we have used HO to stimulate recombination in mitotic cells.

We have shown that the invasion of DNA strands into a donor template region requires the action of the chromatin remodeling protein Rad54 that enables the recombination machinery to gain access to "closed" regions of DNA. The Haber laboratory focuses on understanding mutations that are acquired by tumors and render them susceptible to specific targeted drug therapies. Visit my ORCI D page for more information..

David Housman was born on July 20, 1946. Articles tagged with 'Haber Lab' at Undergraduate Research. We are analyzing mutants of yeast that fail to respond normally to these checkpoint signals. Contact Information. (2015). See below for the WeSSLLI schedule of courses and workshops, and for the WeSSLLI+ESSLLI student session schedule. In addition to determining how this process occurs and how various mutations affect it, we are particularly interested in the phenomenon of donor preference, whereby MATa cells choose the donor on the left while MAT elects to recombine with the donor on the right, even if we replace HML by HMR; it is the position on the chromosome that dictates donor choice. Academic career. Joe presented his work on selective autophagy in pancreatic cancer and the Mancias Lab future directions. The two donor loci are maintained in a chromatin configuration that prevents them from being transcribed or being cleaved by the HO endonuclease that cuts the same sequence at MAT to initiate switching.
