Summary: Enables ATP hydrolysis activity and metallopeptidase activity. Involved in protein import into mitochondrial matrix; protein-containing complex assembly; and signal peptide processing. Located in mitochondrial inner boundary membrane. Part of m-AAA complex. Used to study hereditary spastic paraplegia; optic atrophy 12; and spinocerebellar ataxia type 28. Human ortholog(s) of this gene implicated in optic atrophy 12; spastic ataxia; spastic ataxia 5; and spinocerebellar ataxia type 28. Orthologous to human AFG3L2 (AFG3 like matrix AAA peptidase subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

replacement of the Yta10 TM2 domain abolishes membrane dislocation for only a subset of substrates, whereas replacement of the Yta12 TM2 domain impairs membrane dislocation for all tested substrates, suggesting different roles of the TM domains in each m-AAA protease subunit
Title: Molecular insights into the m-AAA protease-mediated dislocation of transmembrane helices in the mitochondrial inner membrane.
Observations show a role for the mitochondrial protease Afg3 in modulating cytoplasmic mRNA translation and ER stress resistance, and suggest Afg3 modulates longevity in yeast by a mechanism similar to cytoplasmic ribosomal large subunit proteins.
Title: Stress profiling of longevity mutants identifies Afg3 as a mitochondrial determinant of cytoplasmic mRNA translation and aging.
Inactivation of either of the mitochondrial AAA proteases, Yme1 or Yta10/12, allows fermentative growth of hsc82 or hsp82 strains at 37 degrees C.
Title: Hsp90 and mitochondrial proteases Yme1 and Yta10/12 participate in ATP synthase assembly in Saccharomyces cerevisiae.
Results describe the localizations of the m-AAA protease, its subunits Yta10 and Yta12, and its substrate cytochrome c peroxidase (Ccp1) within yeast mitochondria.
Title: The m-AAA protease processes cytochrome c peroxidase preferentially at the inner boundary membrane of mitochondria.
transmembrane segments of m-AAA protease subunits have a direct role in the dislocation of membrane-embedded substrates
Title: Membrane protein turnover by the m-AAA protease in mitochondria depends on the transmembrane domains of its subunits.
