CC -!- FUNCTION: Co-chaperone that regulates diverse cellular pathways, such
CC as programmed cell death and stress responses. {ECO:0000250}.
CC -!- SUBUNIT: Binds to the ATPase domain of HSP70/HSC70 chaperones (By
CC similarity). Interacts with HSP70-1. {ECO:0000250,
CC ECO:0000269|PubMed:16636050}.
CC -!- TISSUE SPECIFICITY: Detected in stems, leaves, flowers and roots.
CC {ECO:0000269|PubMed:16636050}.
CC -!- INDUCTION: By cold, by salicylic acid (SA), by abscisic acid (ABA) and
CC by pathogen B.cinerea attack. {ECO:0000269|PubMed:16636050}.
CC -!- DISRUPTION PHENOTYPE: Early flowering and shorter vegetative and
CC reproductive phases, with more branched roots and inflorescences. Early
CC senescence. Enhanced susceptibility to salt stress. Hypersensitivity to
CC light. {ECO:0000269|PubMed:16636050}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAM63329.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
