GTP dependent ribosome recycling factor mitochondrial 2

NCBI Gene: 84340ENSG00000164347UniProt: Q969S9

Mitochondrial GTPase that mediates the disassembly of ribosomes from messenger RNA at the termination of mitochondrial protein biosynthesis (PubMed:19716793, PubMed:33878294). Acts in collaboration with MRRF (PubMed:19716793, PubMed:33878294). Promotes mitochondrial ribosome recycling by dissolution of intersubunit contacts (PubMed:33878294). GTP hydrolysis follows the ribosome disassembly and probably occurs on the ribosome large subunit (PubMed:19716793). Not involved in the GTP-dependent ribosomal translocation step during translation elongation (PubMed:19716793)

Population Genetics & Constraint

gnomAD
Tolerant — LoF & missense variants common in population
LoF Constraint?LOEUF (Loss-of-function Observed/Expected Upper bound Fraction) is the upper bound of the 90% CI for LoF OE — the preferred gnomAD v4 metric. Lower = more intolerant to LoF. LOEUF < 0.35 = highly constrained.

Highly tolerant — LoF variants common in population

Missense Constraint?Missense Z-score: standard deviations fewer missense variants observed vs. expected. Z > 3.09 (p < 0.001) = gene does not tolerate missense variation. OE missense < 0.6 is also considered constrained.
