Abstract
Association-controllable hemoprotein assemblies were constructed from a fusion protein containing two c-type cytochrome units using 3D domain swapping. The hemoprotein assembly exhibited a dynamic exchange between cyclic and linear structures and could be regulated by carbon monoxide (CO) and imidazole binding.

Structural and thermodynamic insights into antibody light chain tetramer formation through 3D domain swapping. Nat Commun 2023; 14:7807. [PMID: 38065949 PMCID: PMC10709643 DOI: 10.1038/s41467-023-43443-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 11/07/2023] [Indexed: 12/18/2023] Open
Abstract
Overexpression of antibody light chains in small plasma cell clones can lead to misfolding and aggregation. On the other hand, the formation of amyloid fibrils from antibody light chains is related to amyloidosis. Although aggregation of antibody light chain is an important issue, atomic-level structural examinations of antibody light chain aggregates are sparse. In this study, we present an antibody light chain that maintains an equilibrium between its monomeric and tetrameric states. According to data from X-ray crystallography, thermodynamic and kinetic measurements, as well as theoretical studies, this antibody light chain engages in 3D domain swapping within its variable region. Here, a pair of domain-swapped dimers creates a tetramer through hydrophobic interactions, facilitating the revelation of the domain-swapped structure. The negative cotton effect linked to the β-sheet structure, observed around 215 nm in the circular dichroism (CD) spectrum of the tetrameric variable region, is more pronounced than that of the monomer. This suggests that the monomer contains less β-sheet structures and exhibits greater flexibility than the tetramer in solution. These findings not only clarify the domain-swapped structure of the antibody light chain but also contribute to controlling antibody quality and advancing the development of future molecular recognition agents and drugs.

The past, present, and future of artificial zinc finger proteins: design strategies and chemical and biological applications. J Biol Inorg Chem 2023; 28:249-261.

Abstract
Zinc finger proteins are abundant in the human proteome and are responsible for a variety of functions. The domains that constitute zinc finger proteins are compact spherical structures, each comprising approximately 30 amino acid residues, but they also have precise molecular factor functions: zinc binding and DNA recognition. Due to the biological importance of zinc finger proteins and their unique structural and functional properties, many artificial zinc finger proteins have been created and are expected to improve their functions and biological applications. In this study, we review previous studies on the redesign and application of artificial zinc finger proteins, focusing on the experimental results obtained by our research group. In addition, we systematically review various design strategies used to construct artificial zinc finger proteins and discuss in detail their potential biological applications, including gene editing. This review will provide relevant information to researchers involved or interested in the field of artificial zinc finger proteins as a potential new treatment for various diseases.
