Comments concerning this interaction

Source was live S2 cells; bait produced from transfected construct; prey produced from transfected construct.

Orc6 forms dimers in vivo at the plasma membrane, but not in the nucleus or cytoplasm, as deduced by FRET analysis of live S2 cells.

Comments concerning this interaction

Source was cell extract of baculovirus-infected cell line; protein produced and purified from transfected construct.

Orc6 forms dimers in vitro.

Orc6 dimerization is important for Orc6-facilitated septin filament formation.

Purified Orc6 was separated by size exclusion chromatography and fractions analyzed by western blot.
