Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

CTCF tethers an insulator to subnuclear sites, suggesting shared insulator mechanisms across species.

Yusufzai TM, Tagami H, Nakatani Y, Felsenfeld G

Insulators can block an enhancer of one gene from activating a promoter on another nearby gene. Almost all described vertebrate insulators require binding of the regulatory protein CTCF for their activity. We show that CTCF copurifies with the nucleolar protein nucleophosmin and both are present at insulator sites in vivo. Furthermore, exogenous insulator sequences are tethered to the nucleolus in ...

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
