There are many aspects of my Brandeis education for which I am thankful for; however, being able to work on my own research project at the Haber lab was by far the most significant and influential one. Chromatin assembly factors Asf1 and CAF-1 have overlapping roles in deactivating the DNA damage checkpoint when DNA repair is complete. We have identified the proteins necessary to carry out the initial steps in strand invasion and the beginning of new DNA synthesis, which is significantly different from the normal process of replication. Protein phosphatases pph3, ptc2, and ptc3 play redundant roles in DNA double-strand break repair by homologous recombination. Chromosome position determines the success of double-strand break repair. 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). Office of the Vice Provost for Research: I was so happy to meet you at the Alan Alda Center for Communicating Science … About. Dotiwala F, Eapen VV, Harrison JC, Arbel-Eden A, Ranade V, Yoshida S, Haber JE. DNA damage checkpoint triggers autophagy to regulate the initiation of anaphase. Mec1/Tel1-dependent phosphorylation of Slx4 stimulates Rad1-Rad10-dependent cleavage of non-homologous DNA tails. At Macklis lab I enjoy aiding and assisting our many talented researchers while honing my own skills and developing a multitude of new ones. (2013). Homology Requirements and Competition between Gene Conversion and Break-Induced Replication during Double-Strand Break Repair. Author information. Using budding yeast as a model system throughout his career, Jim has been a major contributor to our understanding of the processing … Multiplexed precision genome editing with trackable genomic barcodes in yeast. Lydeard JR, Jain S, Yamaguchi M, Haber JE. I graduated from Brandeis University with a Bachelor's in … Re-establishment of nucleosome occupancy during double-strand break repair in budding yeast. See below for the WeSSLLI schedule of courses and workshops, and for the WeSSLLI+ESSLLI student session schedule. A pathway of targeted autophagy is induced by DNA damage in budding yeast. Other protocols that we use in our laboratory can be found in commonly used molecular biology lab manuals and on the web. This finding triggered the applicatio… In addition to repair of a double-strand chromosomal break by homologous recombination mechanisms, we have also demonstrated that yeast--like mammalian cells--also employ several nonhomologous repair pathways. We will send you information for joining the event(s) shortly before the start of WeSSLLI … Lisa Haber-Chalom (Lab Manager & Research Coordinator) E-mail: lhchalom@rutgers.edu. Haber JE. As one of the first postdocs in the lab … DNA Repair: The Search for Homology. (2015). (2014). Break-induced replication repair of damaged forks induces genomic duplications in human cells. Mutations arising during repair of chromosome breaks. … We have identified a number of adaptation-defective mutations where cells remain permanently arrested. WeSSLLI 2020 @ Brandeis. (2014). WeSSLLI 2020 @ Brandeis. Berkeley. We employ a combination of theory and experimentation on single molecules and single cells; while we do not have our own lab space, experiments by students in the group are carried out in life-sciences laboratories at Brandeis that we partner with, currently the Gelles, Haber, and Goode labs. Jessica Star. His research focuses on how cells repair breaks in the DNA of chromosomes that arise from errors in DNA replication, from other endogenous problems, or from irradiation. Victoria Sanchez. Download Full PDF Package. Break-induced replication and telomerase-independent telomere maintenance require Pol32. James Haber is a professor of biology and the director of the Rosenstiel Basic Medical Sciences Research Center at Brandeis University. The Graduate School of Arts and Sciences (GSAS) at Brandeis University in Waltham, Massachusetts, United States was established in 1953 on a 235-acre suburban campus, located 9 miles outside of Boston, and is one of four graduate schools on campus.. Brandeis University, founded in 1948, is named for the late U.S. Supreme Court Justice Louis Dembitz Brandeis … Tsabar, M., D. P. Waterman, F. Aguilar, L. Katsnelson, V. V. Eapen, G. Memisoglu and J. E. Haber (2016). Articles tagged with 'Haber Lab' at Undergraduate Research. We will send you information for joining the event(s) shortly before the start of WeSSLLI … As Research Coordinator in the Gluck lab, I am responsible for the compliance of all documentation regarding human subject testing. Some mutants appear to enhance end-resection and generate more signal. Using synchronized cells undergoing recombination that is initiated at a specific site on a chromosome by an inducible endonuclease, we use physical monitoring techniques (Southern blots, PCR analysis) to follow the sequence of molecular events that occur in real time. MAT switching is an example of a repair process called gene conversion. Prakash R, Satory D, Dray E, Papusha A, Scheller J, Kramer W, et al. He received his A.B. 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. Email: haber@brandeis.edu such as DNA damage can have profound Subsequently we showed that deletions effects on cytoplasmic processes and fur- of genes encoding other GARP proteins Punctum to: Dotiwala F, Eapen VV, Harrison JC, ther expand the burgeoning connections (VPS52, VPS53, VPS54 … A short summary of this paper. Haber Lab Research Graduate students Brenda Lemos (left) and Daneille Gallagher ask which proteins are involved in double strand breaks in DNA. 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. The first talk of the 2014-2015 school year will be given by Grace Rosen of the Gelles Lab: Lazzaro F, Sapountzi V, Granata M, Pellicioli A, Vaze M, Haber JE, et al.
