Comments concerning this interaction

Caf1-55, MTA1-like, HDAC1 and MBD-like were coexpressed in a baculovirus expression system, the core NuRD complex affinity purified, and subject to size exclusion chromatography.

Multi-angle laser light scattering of the complex indicated a molecular mass of ~600 kDa.

Source was cell extract of baculovirus-infected Sf21 cell line; bait produced from transfected construct; prey produced from transfected construct.
