The purpose of Current Protein & Peptide Science is to present summaries of specific aspects of research involving proteins, peptides, and interactions between the enzymes, especially proteases; the binding interactions of hormones and their receptors; the properties of transcription factors and other molecules that regulate gene expression; the reactions leading to the immune response; the process of signal transduction; the structure and function of proteins involved in the cytoskeleton and molecular motors; the properties of membrane channels and transporters; and the generation and storage of metabolic energy. In addition, experimental studies of protein folding and design are given special emphasis.
