>cd03054 GST_N_Metaxin GST_N family, Metaxin subfamily; composed of metaxins and related proteins. Metaxin 1 is a component of a preprotein import complex of the mitochondrial outer membrane. It extends to the cytosol and is anchored to the mitochondrial membrane through its C-terminal domain. In mice, metaxin is required for embryonic development. In humans, alterations in the metaxin gene may be associated with Gaucher disease. Metaxin 2 binds to metaxin 1 and may also play a role in protein translocation into the mitochondria. Genome sequencing shows that a third metaxin gene also exists in zebrafish, Xenopus, chicken and mammals. Sequence analysis suggests that all three metaxins share a common ancestry and that they possess similarity to GSTs. Also included in the subfamily are uncharacterized proteins with similarity to metaxins, including a novel GST from Rhodococcus with toluene o-monooxygenase and glutamylcysteine synthetase activities.
