Tim44-like (IPR039544) includes the mitochondrial import inner membrane translocase subunit Tim44 and its bacterial homologs. They all possess a domain that is similar to Tim44. Tim44 is an important part of the PAM complex, which moves proteins with transit peptides from the inner membrane to the mitochondrial matrix with the help of ATP. It recruits mitochondrial HSP70 and uses ATP as an energy source to facilitate protein translocation into the matrix.
