The specific ubiquitin linkages were also determined by mass spectrometry.
Source was adults of transgenic fly line; bait produced from tagged transgenic construct; prey produced from endogenous gene.
morgue specifically associates with K48-linked ubiquitin multimers.
Source was adults of transgenic fly line; bait produced from tagged transgenic construct; prey produced from endogenous gene.
morgue specifically associates with ubiquitin multimers.
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.
Both the N-terminal and C-terminal regions of morgue bind polyubiquitin.
