Here, we used a workflow with lysine-specific crosslinking and offline nano-liquid chromatography matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry to explore the interaction between the plant small heat-shock protein Hsp21 and a thermosensitive model substrate protein, malate dehydrogenase.

24, 2018. The chloroplast‐localized small heat shock protein Hsp21 associates with the thylakoid membranes in heat‐stressed plants. K Bernfur, G Rutsdottir,

Using a reverse genetics approach We took interest in Hsp21, a chloroplast-localized sHsp crucial for plant stress resistance, which has even longer N-terminal arms than Hsp16.9, with a functionally 3 May 2017 Structural model of dodecameric heat-shock protein Hsp21: Flexible N-terminal arms interact with client proteins while C-terminal tails maintain The apparent size of native HSP21 complexes was > 200 kD and they did not dissociate during heat stress. We found no evidence that HSP21 or the plant HSP21 | Chloroplastic heat shock protein. Product information. Immunogen. Recombinant Hsp21 protein derived from the sequence of Arabidopsis thaliana Identification of core subunits of photosystemÂ II as action sites of HSP21, which is activated by the GUN5â€ mediated retrograde pathway in Arabidopsis [2017]. Heat shock protein 21, chloroplastic · HSP21 ·

This section provides any useful information about the protein, mostly biological knowledge.

Those interactions were detected by several methods such as yeast two hybrid, co-IP, pull-down and so on. We selected proteins and molecules interacted with HSP21 here. Most of them are supplied by our site. Hope this information will be useful for your research of HSP21.

The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function.

Furthermore, we show that HSP21 interacts with plastid nucleoid protein pTAC5, which is also essential for maintaining PEP function under heat stress. Our results deﬁne pTAC5 as a physiological target of HSP21 and In Paper D, cryo-electron microscopy together with complementary structural methods, obtained a structure model which showed that the Hsp21 dodecamer (12-mer) is kept together by paired C-terminal interactions.The human protein DNAJB6 functions as a very efficient suppressor of polyglutamine (polyQ) and amyloid-β42 (Aβ42) aggregation. We found that sustained memory requires that HSP21 levels remain high and that HSP21 abundance is regulated by FtsH6. Lack of a functional FtsH6 protein promotes HSP21 accumulation during the later stages of thermomemory and increases thermomemory capacity (Sedaghatmehr et al., 2016). WHIRLY1 Regulates HSP21.5A Expression to Promote Thermotolerance in Tomato Kunyang Zhuang, Kunyang Zhuang State Key Laboratory of Crop Biology, A chloroplast-localized sHsp, Hsp21, provides protection to client proteins to increase plant stress resistance.

Hsp21's skyddande funktion kan alltså regleras genom oxidering/reducering i ett provrör. Exakt hur värme-stress proteinerna fungerar i cellen vet man inte. Genom att använda rent Hsp21 protein och studera Hsp21´s skyddande funktion utanför cellen har vi fått ledtrådar om hur Hsp21 kan fungera i …
