Abstract

Proteins serve as the primary executors of cellular activities in organisms, and thus investigating the subcellular localization and interactions of proteins is crucial for understanding protein functions and elucidating the molecular mechanisms in organisms. Proximity labeling is a recently developed effective method for detecting protein-protein interactions in live cells. Compared with the conventional methods for studying protein-protein interactions, proximity labeling demonstrates high sensitivity, strong specificity, and low background and is widely employed in the research of protein-protein interactions between pathogens and hosts. This article reviews the recent progress in the development and applications of the biotin ligase BirA and its mutants and elucidates the functioning principles of several classical biotin ligases. This review aims to clarify the role of proximity labeling based on BirA and its mutants in identifying protein-protein interactions between pathogens and hosts.

Keywords: BirA; biotin; interaction; protein; proximity labeling.
