Protein

Probable mitochondrial import receptor subunit TOM20

Gene

TOM20

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Central component of the receptor complex responsible for the recognition and translocation of cytosolically synthesized mitochondrial preproteins. Together with TOM22 functions as the transit peptide receptor at the surface of the mitochondrion outer membrane and facilitates the movement of preproteins into the translocation pore (By similarity).By similarity

Miscellaneous

In mammals and fungi, the transmembrane domain is located at the N-terminus while it is located at the C-terminus in plants. The overall orientation of the protein in the membrane is therefore inverted.
