👉 Dimers, also known as dimeric proteins or di- and tetrameric proteins, are a class of protein structures that consist of two identical monomers joined together by a single peptide bond. These structures have been shown to be important in various biological processes such as signal transduction, cell signaling, and the regulation of gene expression. Dimers can be classified based on their formation mechanism. Some dimeric proteins are formed by the spontaneous rearrangement of the two monomer units, while
