Human Mitochondrial import receptor subunit TOM70 (TOMM70A) ELISA Kit

The translocase of outer mitochondrial membrane (TOM) complex is a multisubunit complex involved in the recognition, unfolding, and translocation of preproteins into the mitochondria.TOMM70A is 29% identical to the mitochondrial precursor protein import receptor of Neurospora crassa. RT-PCR analysis detected ubiquitous expression of KIAA0719, with relatively weak expression in pancreas, testis, and spleen.the cytosolic chaperones HSP90 and HSP70 dock onto a specialized tetratricopeptide domain in the import receptor TOMM70 at the outer mitochondrial membrane. This interaction served to deliver a set of preproteins to the receptor for subsequent membrane translocation dependent on the HSP90 ATPase. Disruption of the chaperone/TOMM70 recognition inhibited the import of these preproteins into mitochondria.
