Summary
A member of heat shock protein 90 (HSP90) gene family. Expressed in all tissues and abundant in root apical meristem, pollen and tapetum. Expression is NOT heat-induced but induced by IAA and NaCl. Overexpression reduced tolerance to heat and conferred higher tolerance to calcium.

GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. The amino-terminal and central parts of BES1 are responsible for its physical interaction with HSP90.3 in vitro. Additionally, BZR1 is a novel HSP90 partner aside from two BR signaling components previously identified as its clients.
    Title: Heat shock protein 90 acts in brassinosteroid signaling through interaction with BES1/BZR1 transcription factor.
  2. HSP90s have a central role in sustaining BIN2 nuclear function. BR signaling is mediated by HSP90 activity and via trafficking of BIN2-HSP90 complexes into the cytoplasm. [HSP90.3]
    Title: Brassinosteroid nuclear signaling recruits HSP90 activity.
  3. These results suggest that the preferential translation of Hsp81-3 mRNA in heat-shocked Arabidopsis cells involves a ribosome scanning from the 5'-end of the 5'-UTR rather than ribosome entry to the internal site.
    Title: Preferential translation mediated by Hsp81-3 5'-UTR during heat shock involves ribosome entry at the 5'-end rather than an internal site in Arabidopsis suspension cells.
