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.

Oligomeric complexes link Rab5 effectors with NSF and drive membrane fusion via interactions between EEA1 and syntaxin 13.

McBride HM, Rybin V, Murphy C, Giner A, Teasdale R, Zerial M

SNAREs and Rab GTPases cooperate in vesicle transport through a mechanism yet poorly understood. We now demonstrate that the Rab5 effectors EEA1 and Rabaptin-5/Rabex-5 exist on the membrane in high molecular weight oligomers, which also contain NSF. Oligomeric assembly is modulated by the ATPase activity of NSF. Syntaxin 13, the t-SNARE required for endosome fusion, is transiently incorporated into the ... [more]
