Screening For Binding Partners And Protein-Protein Interactions Of A Fungal Transcription Factor- Xdr1, Nishadi Punsara Gallala Gamage
Screening For Binding Partners And Protein-Protein Interactions Of A Fungal Transcription Factor- Xdr1, Nishadi Punsara Gallala Gamage
Masters Theses
Clarireedia spp. (formerly Sclerotinia homoeocarpaF.T. Bennett) is the causal agent dollar spot, the most economically important turfgrass disease impacting golf courses in North America. The most effective strategy for dollar spot control is repeated application of multiple classes of fungicides. However, reliance on chemical application has led to resistance to four classes of fungicides as well as multidrug resistance (MDR). Fungi are known to detoxify xenobiotics, like fungicides, through transcriptional regulation of three detoxification phases: modification, conjugation and secretion. Little is known, however, of the protein-protein interactions that facilitate these pathways. Following next-generation RNA sequencing of Clarireedia spp., a …

Characterization And Discovery Of Short Linear Motifs Mediating Protein Nuclear Import, Tanner M. Tessier
Electronic Thesis and Dissertation Repository
Protein-protein interactions (PPI) mediated through short linear motifs (SLiMs) are ubiquitous throughout the human proteome and are involved in many essential cellular processes. One such type of SLiM is the classical nuclear localization sequence (cNLS), which facilitates nuclear import by binding importin-α (Imp-α). This pathway is indispensable to many cellular processes and is extensively used by viral proteins that function within the nucleus of infected cells. Based on this, I demonstrated that the classical nuclear import pathway inhibitor, ivermectin, can inhibit replication of human adenovirus. Treatment with ivermectin blocks nuclear localization of the E1A protein, an essential viral nuclear protein …
Nascent Dna Proteomics Analysis Uncovers Dna Replication Dynamics In The Human Pathogen Trypanosoma Brucei, Maria Rocha Granados
Nascent Dna Proteomics Analysis Uncovers Dna Replication Dynamics In The Human Pathogen Trypanosoma Brucei, Maria Rocha Granados
Doctoral Dissertations
DNA is the substrate of many cellular processes including DNA replication, transcription and chromatin remodeling. These processes are coordinated to maintain genome integrity and ensure accurate duplication of genetic and epigenetic information. Genome-wide studies have provided evidence of the relationship between transcription and DNA replication timing. A global analysis of DNA replication initiation in T. brucei showed that TbORC1 (subunit of the origin recognition complex, ORC) binding sites are located at the boundaries of transcription units. Although recent studies in T. brucei indicate functional links among DNA replication and transcription, the underlying mechanisms remain unknown. In this study, we adapted …
Investigation Of Respiratory Syncytial Virus Structural Determinants And Exploitation Of The Host Ubiquitin System, Jillian Nicole Whelan
Investigation Of Respiratory Syncytial Virus Structural Determinants And Exploitation Of The Host Ubiquitin System, Jillian Nicole Whelan
USF Tampa Graduate Theses and Dissertations
Respiratory syncytial virus (RSV) is a globally circulating, non-segmented, negative sense (NNS) RNA virus that causes severe lower respiratory infections. This study explored several avenues to ultimately expand upon our understanding of RSV pathogenesis at the protein level. Evaluation of RSV intrinsic protein disorder increased the relatively limited description of the RSV structure-function relationship. Global proteomics analysis provided direction for further hypothesis-driven investigation of host pathways altered by RSV infection, specifically the interaction between the RSV NS2 protein and the host ubiquitin system. NS2 primarily acts to antagonize the innate immune system by targeting STAT2 for proteasomal degradation. The goal …
Comparison Of Immune Correlates, Age Related Changes And Proteomic Profiling Of Healthy Individuals Receiving Influenza Vaccines, Gaurav Basu
Theses and Dissertations in Biomedical Sciences
The burden of influenza related infections is substantial, both in terms of illness, lives lost and economic impact on society. The degree of impact of influenza related infections is much higher in the elderly population where it is a leading cause of catastrophic disability; greatly affecting the quality of life of elderly persons above 65 years of age. Vaccination is the mainstay for control and prevention of influenza infections. There are two vaccine formulations that are licensed for use at present. The inactivated influenza vaccines (TIIV) which have been used for 60 years in all age groups and the new …
