Human mitochondrial translational initiation factor 3 (IF3mt) has been identified from the human expressed sequence tag data base and the predicted mature form of IF3mt was cloned, and the protein was expressed in Escherichia coli in a His-tagged form.
Evidence for an active role of IF3mt in the initiation of translation in mammalian mitochondria.

The results suggest that IF3(mt) plays an active role in initiation of translation, and appears to lead to a factor defective in the ability to displace the large subunit of the ribosome from the 55S monosomes in an active process.

The cryo-EM structure analysis of the small (28S) subunit (SSU) of the 55S mitoribosome is presented, finding that the mito-specific extensions in homologous MRPs generally are involved in inter-MRP contacts and in contacts with mito -specific MRPs, suggesting a stepwise evolution of the current architecture of the mitorIBosome.
