multiple Puf proteins coordinately regulate YHB1 mRNA to protect cells from nitric oxide stress.
Title: Conditional regulation of Puf1p, Puf4p, and Puf5p activity alters YHB1 mRNA stability for a rapid response to toxic nitric oxide stress in yeast.
The results point to the stress-related proteins Ahp1, Yhb1 and Oye2, as well as Gln1 and Kes1 as putative candidates for being evaluated as biomarkers for diagnostic assays of S. cerevisiae infections.
Title: Immunoproteomic profiling of Saccharomyces cerevisiae systemic infection in a murine model.
YHb functions in oxidative stress indirectly by consuming NO, which inhibits mitochondrial respiration and leads to enhanced production of reactive oxygen species
Title: Yeast flavohemoglobin, a nitric oxide oxidoreductase, is located in both the cytosol and the mitochondrial matrix: effects of respiration, anoxia, and the mitochondrial genome on its intracellular level and distribution.

Nitric oxide oxidoreductase; flavohemoglobin that plays role in oxidative and nitrosative stress responses; protects against nitration of cellular targets and against cell growth inhibition under aerobic or anaerobic conditions; yeast flavohemoglobin Yhb1p and human homolog neuroglobin NGB protect cells against alpha-synuclein cytotoxicity and aggregate formation; protein increases in abundance, relocalizes from nucleus to cytoplasmic foci upon DNA replication stress
