TAR DNA-binding protein 43 (TDP-43) is a nuclear RNA/DNA binding protein involved in mRNA metabolism. Aberrant mislocalization to the cytoplasm and formation of phosphorylated/aggregated TDP-43 inclusions remains the hallmark pathology in a spectrum of neurodegenerative diseases, including frontotemporal disorders and Alzheimer's disease. Eukaryotic Translation Initiation Factor 5A undergoes a unique post-translation modification of lysine to hypusine (K50), which determines eIF5A binding partners. We used a sodium arsenite-induced cellular stress model to investigate the role of hypusinated eIF5A (eIF5AHypK50) in governing TDP-43 cytoplasmic mislocalization and accumulation in stress granule. Our proteomics and functional data provide evidence that eIF5A interacts …

Seton Hall University Dissertations and Theses (ETDs)
This dissertation reports the synthesis and biological applications of bifunctional trimeric peptides with B7H6-derived NKp30 binding motifs that serve to activate an immunocytotoxic response in natural killer cells and a GRP78-binding motif that can target tumors that express surface GRP78. In this manner the cancer-targeting immunostimulatory peptides are anticipated to directly bind and activate effector NK92-MI cells while also recognizing and binding to target A549 tumor cells to facilitate NK cell-dependent immunocytotoxicity of the targeted tumors. The NKp30 binding peptide motifs are derived from the tumor associated B7H6 antigen that is often downregulated or shed from the surface of tumors …
