Functional Description
 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. 
Sequence Annotation
