Role Of Integrase-Pp2a Interaction In Human T-Cell Leukemia Virus Type-1 Replication And Pathogenesis, Shayna Turbin
Senior Honors Papers / Undergraduate Theses
Human T-cell leukemia virus type-1 (HTLV-1) is an oncogenic retrovirus that causes multiple disorders, including adult T-cell leukemia and HTLV-1-associated myelopathy/tropical spastic paraparesis. HTLV-1 retroviral integrase binds to the regulatory B’56γ subunit of the host cell Protein Phosphatase 2A (PP2A). Integrase contains a highly conserved LxxIxE motif that is essential for binding, which increases integration efficiency and facilitates HTLV-1 hijack of host cell machinery. We aim to understand how mutations introduced in the highly conserved binding site can affect viral particle production and infectivity. We transfected 729B human lymphoblastoid cells and 293T cells with mutant and wildtype virus. Mutations L213A, …

Arts & Sciences Electronic Theses and Dissertations
Human immunodeficiency virus type 1 (HIV-1) relies on a handful of essential enzymes for replication. Among these, the viral integrase enzyme (IN) plays a pivotal role in the viral life cycle by catalyzing the integration of the reverse-transcribed viral DNA into the host chromosome. While integration is the canonical role of IN, new research has uncovered an additional vital role for IN during virion morphogenesis. This dissertation elucidates how IN contributes to proper packaging of the viral RNA genome (vRNA) within the viral capsid and examines the fate of improperly formed viral particles in target cells.IN is proposed to mediate …
