HSP21.7 - 21.7 kDa class VI heat shock protein - Arabidopsis thaliana (Mouse-ear cress) - HSP21.7 gene & protein UniProtKB - Q9FIT9 (HS217_ARATH)

A structure model of Hsp21, obtained by homology modeling, single-particle electron microscopy, and lysine-specific chemical crosslinking, shows that the Hsp21 subunits are arranged in two hexameric discs, rotated by 25 degree in relation to each other. We show that an Arabidopsis thaliana knockout mutant of HSP21 had an ivory phenotype under heat stress. Quantitative real-time RT-PCR, run-on transcription, RNA gel blot, and polysome association analyses demonstrated that HSP21 is involved in plastid- encoded RNA polymerase (PEP)–dependent transcription.

Here, we used a set of Arabidopsis mutants such as salicylic acid (SA) signaling mutants nonexpressor of pathogenesis-related gene 1 (npr1-1 and npr1-5) and heat-shock proteins (HSPs) mutants (hsp21 and hsp70-1) to understand the requirement of SA signaling and HSPs in elevated CO2-induced HS tolerance.

"Chloroplast small heat shock protein HSP21 interacts with plastid nucleoid protein pTAC5 and is essential for chloroplast development in Arabidopsis under heat stress." Zhong L., Zhou W., Wang H., Ding S., Lu Q., Wen X., Peng L., Zhang L., Lu C. The chloroplast-localized sHsp, named Hsp21 with reference to its monomeric size, has an N-terminal region that is some 40 amino acids longer compared to the cytosolic sHsps, and increases plant stress tolerance as shown by Arabidopsis thaliana plants which overexpress Hsp21.

Here, we used a set of Arabidopsis mutants such as salicylic acid (SA) signaling mutants nonexpressor of pathogenesis-related gene 1 (npr1-1 and npr1-5) and heat-shock proteins (HSPs) mutants (hsp21 and hsp70-1) to understand the requirement of SA signaling and HSPs in elevated CO2-induced HS tolerance. We have also analyzed isolated Arabidopsis HSP21 protein, purified in large amounts as recombinant protein after overexpression in E. coli. The HSP21 protein belongs to the small heat shock proteins (sHSPs), which share an evolutionary conserved C-terminal domain with α-crystallin [1]. Encodes Hsp21, a chloroplast located small heat shock protein. A structure model of Hsp21, obtained by homology modeling, single-particle electron microscopy, and lysine-specific chemical crosslinking, shows that the Hsp21 subunits are arranged in two hexameric discs, rotated by 25 degree in relation to each other.

In Arabidopsis, the involvement of tetrapyrrole in retrograde signaling was identiﬁed in gen-ome-uncoupled mutants (gun) that continuously express photosynthesis-associated nuclear genes (PhANG), includ-ing the light-harvesting complex of photosystem II (Lhcbs) Using transgenic Arabidopsis thaliana plants that overexpress Hsp21 I found that Hsp21 improves the plant performance during concomitant heat and light stress and that Hsp21 undergoes conformational changes during stress. LifeSpan BioSciences currently sells 2 antibodies specific for Arabidopsis thaliana HSP21. Chloroplast small heat shock protein HSP21 interacts with plastid nucleoid protein pTAC5 and is essential for chloroplast development in Arabidopsis under heat stress. Compared with small heat shock proteins (sHSPs) in other organisms, those in plants are the most abundant and diverse.
