Function

TOM22_YEAST Central component of the TOM (translocase of outer membrane) receptor complex responsible for the recognition and translocation of cytosolically synthesized mitochondrial preproteins. Together with TOM20 and TOM70 functions as the transit peptide receptor at the surface of the mitochondrion outer membrane and facilitates the movement of preproteins into the TOM40 translocation pore. Docks TOM20 and TOM70 for interaction with the general TOM40 import pore (GIP) complex. May regulate the TOM machinery organization, stability and channel gating.^{[1] [2] [3]}
