Mitochondrial import receptor subunit Tom22, fungi (IPR020951)

Short name: Tom22_fungi

Overlapping homologous superfamilies


Family relationships


Tom22 is a central component of the TOM (Translocase of Outer Membrane) complex responsible for the recognition and translocation of cytosolically synthesized mitochondrial preproteins. Together with tom20, it functions as the transit peptide receptor at the surface of the mitochondrion outer membrane and facilitates the movement of preproteins into the translocation pore [PMID: 15523480, PMID: 10519552].
