Background Information

RECQ protein-like 4(RECOL4), which has helicase domains contain 7 consensus motifs in the middle, is a gene responsible for Werner syndorme and Bloom syndrome. It forms a stable complex with UBR1 adn UBR2, which has a DNA-stimulated ATPase activity. RECOL4 may involve in repairment of DNA damage by interaction with APE1 and FEN1, key participants in base excision repair. This is a rabbit polyclonal antibody raised against part of C-terminal of RECQ4 of human origin. The calculated molecular weight of EIF3B is 133 kDa, but the modified EIF3B protein is about 145-150 kDa.
