Protein
Mitochondrial import inner membrane translocase subunit TIM44
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Essential component of the PAM complex, a complex required for the translocation of transit peptide-containing proteins from the inner membrane into the mitochondrial matrix in an ATP-dependent manner. Recruits mitochondrial HSP70 and its co-chaperone (MGE1) to drive protein translocation into the matrix using ATP as an energy source.
Similarity
Belongs to the Tim44 family.
