Mitochondrial import receptor subunit TOM34 (TOMM34)

Plays a role in the import of cytosolically synthesized preproteins into mitochondria. Binds the mature part of precursor proteins.

Interacts with mobile components, and possesses weak ATPase activity. May be a chaperone-like protein which helps to keep newly synthesized precursors in an unfolded import harmonious state.
