Introduction:
The Ku autoantigen is a heterodimer of 70kDa (p70) and 80kDa (p80) proteins. AntiKu antibodies are reported in various connective tissue diseases and the Ku complex can be responsible for a very strong autoimmune answer in autoimmune disease.
Description:
Heterodimer expressed in insect Sf9 cells containing a 633 AA (Mw: 72.8 KDa) Ku70 and a 743 AA (Mw: 84.1 KDa) Ku80.
Ku70 has N-terminal 6xHis-tag and TEV cleavage site with 25 extra AA (highlighted), while Ku80 has C-terminal Flag-tag with 21 extra AA (highlighted). Recombinant antigen for research use or manufacturing only.
Immunological Function:
As an autoantigen, Ku70/80 binds with IgG-type human auto-antibodies.
