Chromatin conformations of HSP12 during transcriptional activation in the Saccharomyces cerevisiae stationary phase.
Title: Chromatin conformations of HSP12 during transcriptional activation in the Saccharomyces cerevisiae stationary phase.
PiP2 favors an alpha-helical structure of non-recombinant Hsp12 of Saccharomyces cerevisiae.
Title: PiP(2) favors an α-helical structure of non-recombinant Hsp12 of Saccharomyces cerevisiae.
Using the anhydrobiote, budding yeast, the authors show that trehalose and Hsp12, a small intrinsically disordered protein (sIDP) of the hydrophilin family, synergize to mitigate completely the inviability caused by the lethal stresses of desiccation.
Title: Synergy between the small intrinsically disordered protein Hsp12 and trehalose sustain viability after severe desiccation.
these results demonstrate that the combined action of Hsp12p, Pau5p and a killer toxin is sufficient to steer a yeast community.
Title: Hsp12p and PAU genes are involved in ecological interactions between natural yeast strains.
Hsp12 expression contributes to lifespan extension, possibly via membrane alterations
Title: NMR structure of Hsp12, a protein induced by and required for dietary restriction-induced lifespan extension in yeast.
NMR spectra collected in presence of paramagnetic spin relaxation agents (5DSA, 16DSA, and Gd(DTPA-BMA)) indicated that the amphipathic alpha-helices of Hsp12 in SDS micelles lie on the membrane surface.
Title: Structural characterization of Hsp12, the heat shock protein from Saccharomyces cerevisiae, in aqueous solution where it is intrinsically disordered and in detergent micelles where it is locally α-helical.
Hsp12 is completely unfolded; however, in the presence of certain lipids, it adopts a helical structure. The presence of Hsp12 does not alter the overall lipid composition of the plasma membrane but increases membrane stability.
Title: Hsp12 is an intrinsically unstructured stress protein that folds upon membrane association and modulates membrane function.
The decrease of the turgor pressure in the case of WT strain upon addition of Congo red is shown to be consistent with an upregulation of Hsp12p in the close vicinity of the plasma membrane.
Title: The role of the heat shock protein Hsp12p in the dynamic response of Saccharomyces cerevisiae to the addition of Congo red.
Hsp12 contributes to yeast tolerance to freezing stress. Hsp12p plays a role in freezing tolerance in a way that seems to be interchangeable with trehalose.
Title: Small heat-shock protein Hsp12 contributes to yeast tolerance to freezing stress.
Hsp12p played a role in maintaining plasma membrane integrity during applied oxidative stress.
Title: A compensatory increase in trehalose synthesis in response to desiccation stress in Saccharomyces cerevisiae cells lacking the heat shock protein Hsp12p.
