Ku-core domain, Ku80 subfamily; Ku80 is a subunit of the Ku protein, which plays a key role in multiple nuclear processes such as DNA repair, chromosome maintenance, transcription regulation, and V(D)J recombination. The mechanism underlying the regulation of all the diverse functions of Ku is still unclear, although it seems that Ku is a multifunctional protein that works in nuclei. In mammalian cells, the Ku heterodimer recruits the catalytic subunit of DNA-dependent protein kinase (DNA-PK), which is dependent on its association with the Ku70/80 heterodimer bound to DNA for its protein kinase activity.

Ku70/Ku80 N-terminal domain. The Ku78 heterodimer (composed of Ku70 and Ku80) contributes to genomic integrity through its ability to bind DNA double-strand breaks (DSB) in a preferred orientation. DSB's are repaired by either homologues recombination or non-homologues end joining and facilitate repair by the non-homologous end-joining pathway (NHEJ). The Ku heterodimer is required for accurate process that tends to preserve the sequence at the junction. Ku78 is found in all three kingdoms of life. However, only the eukaryotic proteins have a vWA domain fused to them at their N-termini. The vWA domain is not involved in DNA binding but may very likey mediate Ku78's interactions with other proteins. Members of this subgroup lack the conserved MIDAS motif.

Ku-core domain; includes the central DNA-binding beta-barrels, polypeptide rings, and the C-terminal arm of Ku proteins. The Ku protein consists of two tightly associated homologous subunits, Ku70 and Ku80, and was originally identified as an autoantigen recognized by the sera of patients with an autoimmunity disease. In eukaryotes, the Ku heterodimer contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by non-homologous end-joining. The bacterial Ku homologs does not contain the conserved N-terminal extension that is present in the eukaryotic Ku protein.

Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains.
