RHC31, E1 ubiquitin-activating protein AOS1, L000004031, YPR180W
Subunit of heterodimeric nuclear SUMO activating enzyme E1 with Uba2p; activates Smt3p (SUMO) before its conjugation to proteins (sumoylation), which may play a role in protein targeting; essential for viability; relocalizes to the cytosol in response to hypoxia

Reconstituted Complex

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Ubc9p is the conjugating enzyme for the ubiquitin-like protein Smt3p.

Johnson ES, Blobel G

At least one essential function of Smt3p, a Saccharomyces cerevisiae ubiquitin-like protein similar to the mammalian protein SUMO-1, involves its posttranslational covalent attachment to other proteins. Using Smt3p affinity chromatography, we have isolated the second enzyme of the Smt3p conjugation pathway and have found that it is identical to Ubc9p, a previously identified protein that has extensive sequence similarity to ...
