Mba1 is an inner membrane protein that is part of the mitochondrial protein export machinery [1][2]. It binds to the large subunit of mitochondrial ribosomes and cooperates with the C-terminal ribosome-binding domain of Oxa1, which is a central component of the insertion machinery of the inner membrane. In the absence of both Mba1 and the C-terminus of Oxa1, mitochondrial translation products fail to be properly inserted into the inner membrane and serve as substrates of the matrix chaperone Hsp70 [3]. It is proposed that Mba1 functions as a ribosome receptor that cooperates with Oxa1 in the positioning of the ribosome exit site to the insertion machinery of the inner membrane [3].	Domain
