N-terminal palmitoylation is required for Toxoplasma gondii HSP20 inner membrane complex localization
(Elsevier Science, 2013-03)
Toxoplasma gondii is an obligate intracellular parasite and the causative agent of toxoplasmosis. Protein palmitoylation is known to play roles in signal transduction and in enhancing the hydrophobicity of proteins thus ...
Protein cryoprotective activity of a cytosolic small heat shock protein that accumulates constitutively in chestnut stems and is up-regulated by low and high temperatures
(2004)
Heat shock, and other stresses that cause protein misfolding and aggregation, trigger the accumulation of heat shock proteins (HSPs) in virtually all organisms. Among the HSPs of higher plants, those belonging to the small ...
Structural and functional characterization of the chaperone Hsp70 from sugarcane. Insights into conformational changes during cycling from cross-linking/mass spectrometry assays
(Elsevier B.V., 2014-06-02)
Hsp70 cycles from an ATP-bound state, in which the affinity for unfolded polypeptides is low, to an ADP-bound state, in which the affinity for unfolded polypeptides is high, to assist with cell proteostasis. Such cycling ...
Tandem duplication events in the expansion of the small heat shock protein gene family in solanum lycopersicum (cv. Heinz 1706)
(Genetics Society of America, 2016-10)
In plants, fruit maturation and oxidative stress can induce small heat shock protein (sHSP) synthesis to maintain cellular homeostasis. Although the tomato reference genome was published in 2012, the actual number and ...
Small heat shock proteins and the postharvest chilling tolerance of tomato fruit
(Wiley Blackwell Publishing, Inc, 2017-02)
Plants have the largest number of small heat shock proteins (sHsps) (15–42 kDa) among eukaryotes, but little is known about their function in vivo. They accumulate in response to different stresses, and specific sHsps are ...
EFFECT OF COLCHICINE AND HEAT-SHOCK ON MULTIDRUG-RESISTANCE GENE AND P-GLYCOPROTEIN EXPRESSION IN RAT-LIVER
(ELSEVIER SCIENCE BV, 1994)
The multidrug resistance genes encode plasma membrane glycoproteins named P-glycoproteins, that act as an ATP-dependent drug efflux pump and decrease the cytosolic concentration of chemotherapeutic agents. It has been ...
