Protein Name:
Heat shock 70 kDa protein 1
|
UniprotKB/SwissProt ID: P22953 (P22953)
Gene Name:
HSP70-1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: In cooperation with other chaperones, Hsp70s are key components that facilitate folding of de novo synthesized proteins, assist translocation of precursor proteins into organelles, and are responsible for degradation of damaged protein under stress conditions (Probable). Probably involved in defense response. Chaperone involved in protein targeting to chloroplasts. May cooperate with SGT1 and HSP90 in R gene-mediated resistance towards the oomycete Hyaloperonospora parasitica (downy mildew). Plays a role with WPP-domain proteins in facilitating WIT1 nuclear envelope targeting (PubMed:12805626, PubMed:18065690, PubMed:19617588). Modulates stomatal aperture in response to various environmental conditions and physiological responses to the hormone abscisic acid (ABA) (PubMed:21586649)
