Cartoon representation of ubiquitin-protein, highlighting the secondary structure. α-helices are coloured in blue and β-strands in green. The sidechains of the 7 lysine residues are indicated by orange sticks. The two best-characterised attachment points for further ubiquitin molecules in polyubiquitin chain formation (lysines 48 & 63) are labelled. The image was created using PyMOL from PDB id 1ubi.

Proteins in cells can be ubiquitinated where E3 ligase catalyzes the last step of this process. After conjugating the initial ubiquitin on the target protein, further ubiquitin proteins can be conjugated to the first ubiquitin resulting in a polyubiquitin chain. The conjugation of new ubiquitins to form a poly-chain happens at one of the seven lysines (K) present in ubiquitin. The addition of a new ubiquitin on the lysine at position 63 (K63) provides a different fate to the target protein than if linked to another of the seven lysines.

Our sdAb binds most specifically to this K63 linkage on polyubiquitin chains.
