Protein function research focuses on understanding the specific roles that proteins play in biological processes. This includes studying how proteins interact with other molecules, how they are regulated, and how their functions contribute to various cellular activities such as signaling, metabolism, and DNA replication. Researchers use a variety of experimental techniques, such as protein purification, structural analysis, and functional assays, to investigate the function of proteins in both normal and disease states. The goal of protein function research is to deepen our knowledge of cellular mechanisms and ultimately develop new therapeutics for treating various diseases.
