Comments concerning this interaction

The specific ubiquitin linkages were also determined by mass spectrometry.

(Zhou et al., 2013)

Source was adults of transgenic fly line; bait produced from tagged transgenic construct; prey produced from endogenous gene.

(Zhou et al., 2013)

morgue specifically associates with K48-linked ubiquitin multimers.

Comments concerning this interaction

Source was adults of transgenic fly line; bait produced as a recombinant fusion protein in bacterial system; prey produced as a recombinant fusion protein and polymerized in vitro.

(Zhou et al., 2013)

Both the N-terminal and C-terminal regions of morgue bind polyubiquitin.
