Polyubiquitin chains are composed of ubiquitin monomers that are covalently linked through isopeptide bonds (other than linear, or “Met1-linked” polyubiquitin). Isopeptides are formed between a lysine residue of one Ubiquitin molecule and the C­terminal glycine residue of another Ubiquitin molecule. Seven of the seventy-six amino acids in ubiquitin are lysine residues that can participate in polyubiquitin chain formation. Linkage through specific lysine residues is thought to serve as a signal that affects protein degradation, signaling, trafficking, and other cellular processes. K48-linked polyubiquitin chains attached to substrate proteins often serve as a recognition sequence for targeting and destruction of the substrate by the 26S Proteasome. This antibody detects the K48 linkage. It does not detect monoubiquitin or ubiquitin liked via any other lysine residue. Reactivity across all species is anticipated.
