What's a GeneRIF?
  1. overexpression of Bro1, particularly the V domain, prevented Rfu1 degradation in response to heat shock
    Title: The ESCRT-III adaptor protein Bro1 controls functions of regulator for free ubiquitin chains 1 (Rfu1) in ubiquitin homeostasis.
  2. identified a protein designated Rfu1 (regulator of free ubiquitin chains 1), which regulates intracellular concentrations of monomeric ubiquitins; functions as an inhibitor of Doa4
