HSP81-3 heat shock protein 81-3 [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: HSP81-3
Official Full Name: heat shock protein 81-3
Primary source: TAIR:AT5G56010
Locus tag: AT5G56010
See related: Araport:AT5G56010
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: AtHsp90-3; AtHsp90.3; heat shock protein 81-3; HEAT SHOCK PROTEIN 81.3; HEAT SHOCK PROTEIN 90-3; HEAT SHOCK PROTEIN 90.3; HSP81.2; Hsp81.3; MDA7.5; MDA7_5
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.
