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
CC manner. In the complex, it is required to regulate activity of mtHSP70
CC (SSC1) via its interaction with PAM18/TIM14. May act by positioning
CC PAM18/TIM14 in juxtaposition to mtHSP70 at the translocon to maximize
CC ATPase stimulation. {ECO:0000269|PubMed:14981506,
CC ECO:0000269|PubMed:14981507, ECO:0000269|PubMed:15218029}.
CC -!- SUBUNIT: Homodimer and heterodimer with PAM18. Homodimerization may not
CC be relevant in vivo, while heterodimerization is essential for activity
CC regulation of mtHSP70. Component of the PAM complex, at least composed
CC of mtHsp70, MGE1, TIM44, PAM16, PAM17 and PAM18. Interacts with MDJ2.
CC {ECO:0000269|PubMed:14981506, ECO:0000269|PubMed:14981507,
CC ECO:0000269|PubMed:15218029, ECO:0000269|PubMed:16027163,
CC ECO:0000269|PubMed:16105940, ECO:0000269|PubMed:16107694}.
CC -!- INTERACTION:

CC P42949; Q01852: TIM44; NbExp=3; IntAct=EBI-26019, EBI-9141;
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:14981506, ECO:0000269|PubMed:14981507}; Peripheral
CC membrane protein {ECO:0000269|PubMed:14981506,
CC ECO:0000269|PubMed:14981507}.
CC -!- DOMAIN: The J-like region, although related to the J domain does not
CC stimulate ATPase activity of mtHSP70. It nevertheless mediates the
CC heterodimerization with the J domain of PAM18 and is therefore
CC essential for PAM complex function. {ECO:0000269|PubMed:16105940}.
CC -!- MISCELLANEOUS: Present with 3180 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the TIM16/PAM16 family. {ECO:0000305}.
