CC -!- FUNCTION: Mitochondrial GTPase that mediates the disassembly of
CC ribosomes from messenger RNA at the termination of mitochondrial
CC protein biosynthesis. Acts in collaboration with MRRF. GTP hydrolysis
CC follows the ribosome disassembly and probably occurs on the ribosome
CC large subunit. Not involved in the GTP-dependent ribosomal
CC translocation step during translation elongation. {ECO:0000255|HAMAP-
CC Rule:MF_03059}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000255|HAMAP-Rule:MF_03059}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q8R2Q4-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8R2Q4-2; Sequence=VSP_038195;
CC Name=3;
CC IsoId=Q8R2Q4-3; Sequence=VSP_038196;
CC -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC transit peptide but none has been predicted. {ECO:0000255|HAMAP-
CC Rule:MF_03059}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. EF-G/EF-2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_03059}.
