abnormal ribosome footprint size distribution increased level of short ribosome footprints during endoplasmic reticulum unfolded protein response increased level of short ribosome footprints during ER unfolded protein response increased level of short ribosome footprints during erUPR A cell phenotype observed in the vegetative growth phase of the life cycle in which the distribution of ribosomal footprint lengths in a cell includes more short footprints than wild type when the cell undergoes an endoplasmic reticulum unfolded protein response (UPR). Ribosomal footprints are RNA fragments protected by the ribosome, and normally range from 28-31 nucleotides long. midori 2017-10-23T14:14:08Z increased level of short ribosome footprints during endoplasmic reticulum unfolded protein response during vegetative growth increased level of short ribosome footprints during endoplasmic reticulum unfolded protein response during mitotic cell cycle FYPO:0006255 increased level of short ribosome footprints upon UPR induction
