Protein

Mitochondrial import receptor subunit TOM22 homolog

Gene
TOMM22, TOM22
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Central receptor component of the translocase of the outer membrane of mitochondria (TOM complex) responsible for the recognition and translocation of cytosolically synthesized mitochondrial preproteins. Together with the peripheral receptor TOM20 functions as the transit peptide receptor and facilitates the movement of preproteins into the translocation pore.1 Publication

Domaini

Requires the transmembrane domain (TMD), a short segment (the import sequence) in the cytoplasmic domain localizing separately from the TMD and the C-tail signal in the C-terminal domain for efficient targeting and integration into the TOM complex By similarity. The N-terminal domain (residues 1-62) is important for binding to the unfolded mature imported proteins. Residues (49-71) of the cytoplasmic domain interacts with TOMM20 while the C-terminal segment (residues 63-82) binds presequence of preproteins.

Sequence similaritiesi

Belongs to the Tom22 family.
