Arabidopsis thaliana HSP21 antibody LS-C129571 is an unconjugated rabbit polyclonal antibody to arabidopsis thaliana Arabidopsis thaliana HSP21. Validated for WB. A model for the structure of Hsp21 from Arabidopsis indicates that this plant sHSP is also a dodecamer with two hexameric disks (Lambert et al., 2011). Recently it has become clear that the sHSPs are polydisperse, meaning that more than one oligomeric state is found (Baldwin, 2011). Stengel et al.

Sustained memory requires that HSP21 levels remain high. The Arabidopsis proteins RAR1 and SGT1 are required for the action of many R proteins, and display some structural similarity to HSP90 co‐chaperones. Each associates with HSP90 in plant cells. Our data suggest that (i) RPM1 is an HSP90 client protein; and (ii) RAR1 and SGT1 may function independently as HSP90 cofactors.

and its downstream target gene HSP21 in Arabidopsis (Yu et al., 2012). 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)

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.
