RT repeat proteins in Arabidopsis and rice as putative co-chaperones of

CC -!- FUNCTION: Mediates the association of the molecular chaperones HSP70
CC and HSP90. Mediates nuclear encoded chloroplast preproteins binding to
CC HSP90 prior to chloroplastic sorting (By similarity). Involved in
CC acclimation to heat. {ECO:0000250, ECO:0000269|PubMed:17085506}.
CC -!- SUBUNIT: Co-chaperone that forms a complex with HSP70 and HSP90 and
CC preproteins (e.g. chloroplast preproteins) (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9STH1-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9STH1-2; Sequence=VSP_053940, VSP_053941;
CC -!- DOMAIN: The tetratricopeptide repeat (TPR) domain, forming a
CC carboxylate clamp (CC), mediates interaction with the highly conserved
CC 'EEVD' motif at the C-terminal ends of HSP90 and HSP70. {ECO:0000250}.
CC -!- PTM: Phosphorylated. {ECO:0000250}.
CC -!- PTM: Acetylated. {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Decreased thermotolerance after a long recovery
CC (2 days) under nonstress conditions following an acclimation heat
CC treatment. {ECO:0000269|PubMed:17085506}.
