Mitochondrial assembly of ribosomal large subunit protein 1 (Malsu1)

May be the ribosomal silencing element. Interacts with mitochondrial ribosomal protein L14 (MRPL14), probably blocking formation of intersubunit bridge B8, preventing association of the 28S and 39S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.

May also participate in the regulation or assembly of the stability of the large subunit of the mitochondrial ribosome (By similarity). .
