Function

As a component of the mitochondrial large ribosomal subunit, plays a role in mitochondrial translation. When present in mitochondria as a free protein not associated with the ribosome, associates with mitochondrial RNA polymerase POLRMT to activate transcription. Required for POLRMT stability
