CC -!- FUNCTION: Essential component of the PAM complex, a complex required
CC for the translocation of transit peptide-containing proteins from the
CC inner membrane into the mitochondrial matrix in an ATP-dependent manner
CC (By similarity). Seems to control the nucleotide-dependent binding of
CC mitochondrial HSP70 to substrate proteins (By similarity). Binds ATP
CC (By similarity). Interacts with copper ions Cu(2+) (PubMed:20018591).
CC Confers thermotolerance to long-term exposure at moderately high
CC temperature (TMHT at 35 degrees Celsius) (PubMed:22128139).
CC {ECO:0000250|UniProtKB:P38523, ECO:0000250|UniProtKB:Q9FLP3,
CC ECO:0000250|UniProtKB:Q9HAV7, ECO:0000269|PubMed:20018591,
CC ECO:0000269|PubMed:22128139}.
CC -!- SUBUNIT: Probable component of the PAM complex, at least composed of
CC SSC1 (mtHsp70), MGE1, TIM44, PAM16/TIM16, PAM17 and PAM18/TIM14.
CC Interacts with SSQ1. {ECO:0000250|UniProtKB:P38523}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000269|PubMed:22128139}.
CC -!- INDUCTION: Induced by heat treatment at 38 degrees Celsius in a HSFA1-
CC dependent manner (at protein level). {ECO:0000269|PubMed:22128139}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype in normal conditions.
CC Defective for thermotolerance to moderately high temperature (TMHT at
CC 35 degrees Celsius), but normal basal thermotolerance (BT), short-term
CC acquired thermotolerance (SAT) and long-term acquired thermotolerance
CC (LAT) at 37 and 44 degrees Celsius. {ECO:0000269|PubMed:22128139}.
CC -!- SIMILARITY: Belongs to the GrpE family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAA13686.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
