Function
Regulates ATP-dependent protein translocation into the mitochondrial matrix (By similarity). Involved in the uptake of thaxtomin, a phytotoxin produced by Streptomyces bacteria, that causes dramatic cell swelling, reduced seedling growth, and inhibition of cellulose synthesis (PubMed:12897252, PubMed:23638731). Modulates polar auxin transport (PubMed:23638731). Involved in importing a negative regulator of plant immunity into mitochondria, thus protecting plants from over-accumulation of reactive oxygen species (ROS) and preventing autoimmunity. Confers sensitivity to virulent pathogens such as the oomycete H.arabidopsidis Noco2 and the bacteria P.syringae pv. maculicola ES4326 (PubMed:24153405).
