Identification of a receptor for protein import into mitochondria
D Pain et al. Nature. 1990.
Abstract
Anti-idiotypic antibodies, prepared using a chemically synthesized signal peptide of a mitochondrial precursor protein, recognized a mitochondrial integral membrane protein (p32). Fab fragments derived from both anti-idiotypic antibodies and monospecific antibodies against purified p32 inhibited protein import into mitochondria. Moreover, anti-p32 antibodies specifically immunoprecipitated a precursor-p32 complex after detergent solubilization of mitochondria. Immunoelectron microscopy and subfractionation of mitochondria indicate that p32 is located in contact sites between the outer and inner mitochondrial membranes.
