Antigen Preparation
A Human B cell nuclei from plasmacytoid 2p68 cells
Background
The Ku autoantigen is a heterodimer of 70kDa (p70) and ~80kDa (p80) proteins. The p70/p80 dimer is important for function of a 460 kDa DNA-dependent protein kinase that phosphorylates certain ranscription factors, including Sp1, Oct-1, p53, and SV40 large T antigen in vitro. Ku protein plays a role in cell signaling, proliferation, DNA repair, replication, transcriptional activation, and apoptosis. This antibody recognizes p70/p80 dimer which is destroyed during Western Blot.
