Suppression of the effects of an spt10 mutation on ADH2 expression is a phenotype shared by a small number of genes whose protein products are either components of the CCR4-NOT complex required for mRNA deadenylation and degradation (CCR4, CAF1, NOT4) or have been shown to interact with the complex (DBF2, SRB9, SRB10). In this work, we conducted a screen for additional suppressors of spt10 at ADH2 to identify new factors related to CCR4 function. In addition to reisolating ccr4 and caf1 alleles, three previously unidentified suppressors …


Characterization Of The Infectivity Of Non-Replicating Human Immunodeficiency Virus (Hiv)-Derived Viral Vectors., Vanessa E. Rodriguez, Manuel Llano, Luis Valdes Jul 2012

Characterization Of The Infectivity Of Non-Replicating Human Immunodeficiency Virus (Hiv)-Derived Viral Vectors., Vanessa E. Rodriguez, Manuel Llano, Luis Valdes

COURI Symposium Abstracts, Summer 2012

The ability of HIV-derived viral vectors to integrate genes of interest into the host genome causing permanent phenotypic modifications makes them excellent tools in gene therapy. However, integration also causes insertional mutagenesis and controlling integration site selection will increase the biosafety of these molecular tools. HIV DNA integration site selection is influenced by LEDGF/p75, a chromatin-bound cellular protein that interacts with the viral enzyme integrase through the integrase binding domain (IBD). Integrase catalyzes viral DNA integration and non-covalently associates with the HIV genome forming the pre-integration complex (PIC). Therefore, interaction of chromatin-bound LEDGF/p75 with the PIC-associated integrase tethers the HIV …


The Effects Of Cytokinin On The Transcriptional Regulation Of Pin Expression In Arabidopsis Thaliana, Elizabeth Burgess Jul 2012

The Effects Of Cytokinin On The Transcriptional Regulation Of Pin Expression In Arabidopsis Thaliana, Elizabeth Burgess

Honors Theses and Capstones

The processes of cell division and differentiation are critical to the development of any multicellular organism. During the formation of plant roots these processes take place at a region of the root tip called the meristem. Cytokinin and auxin are two plant growth hormones that influence this process. Although these two growth hormones are both necessary they also appear in many ways to have an antagonistic relationship. As meristematic root cells undergo differentiation they cease dividing. It has been proposed that the size of the root meristem and thus the overall rate of root growth are determined by the balance …

Use Of Two-Dimensional Agarose-Gel Analysis To Characterize Processing Of Uv-Irradiated Plasmids And The Composition Of The Replisome Following Uv-Induced Arrest, Harout Arthur Jeiranian Jan 2012

Use Of Two-Dimensional Agarose-Gel Analysis To Characterize Processing Of Uv-Irradiated Plasmids And The Composition Of The Replisome Following Uv-Induced Arrest, Harout Arthur Jeiranian

Dissertations and Theses

In this thesis, I address two fundamental questions related to our understanding of how DNA damage is processed and repaired during replication. Using Two-dimensional (2-D) agarose gel analysis, I first examine whether DNA damage on plasmids introduced by transformation is processed in a manner similar to that observed on endogenously replicating plasmids and the chromosome. The original intent for using this approach was to develop a technique that could examine how different DNA adducts would be repaired in various sequence contexts. However, I found that distinct differences exist between the processing of DNA damage on transforming plasmids and the chromosome. …
