A Characterization Of Key Residues In Class I Viral Fusion Proteins Important For Fusogenic Activity, Hadley E. Neal
A Characterization Of Key Residues In Class I Viral Fusion Proteins Important For Fusogenic Activity, Hadley E. Neal
Theses and Dissertations--Molecular and Cellular Biochemistry
Viral fusion proteins are critical for viral entry and subsequent infection. Class I fusion proteins are characterized by synthesis as an inactive precursor requiring cleavage by a host cell protease to become fusion competent. Though vaccine and antiviral therapeutic developments often target the fusion protein, questions surrounding cleavage dynamics and protein stability remain. The work presented in this dissertation investigates specific regions of three class I viral fusion proteins in an effort to identify key residues involved in proteolytic processing and membrane fusion.
