UBI4

SCD2, UB14, ubiquitin, L000002414, YLL039C
Ubiquitin; becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; protein abundance increases in response to DNA replication stress

Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

The Vps27p Hse1p complex binds ubiquitin and mediates endosomal protein sorting.

Bilodeau PS, Urbanowski JL, Winistorfer SC, Piper RC

Membrane proteins that are degraded in the vacuole of Saccharomyces cerevisiae are sorted into discrete intralumenal vesicles, analogous to the internal membranes of multi-vesiculated bodies (MVBs). Recently, it has shown that the attachment of ubiquitin (Ub) mediates sorting into lumenal membranes. We describe a complex of Vps27p and Hse1p that localizes to endosomal compartments and is required for the recycling ... [more]

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
