The biological assembly is a filament of alternating homodimers of XRCC4 and XLF. The unit is assembled by the following chains: GF, IH, BA, ED. This has been confirmed by SAXS (Hammel, M., Yu, Y., Fang, S., Lees-Miller, S.P., and Tainer, J.A. (2010). XLF regulates filament architecture of the XRCC4-ligaseIV complex. Structure. 11, 1431-1442.).
