Afg3l2 Gene Summary [Mouse]
Enables metallopeptidase activity. Involved in protein autoprocessing and regulation of calcium import into the mitochondrion. Acts upstream of or within several processes, including mitochondrion organization; nervous system development; and righting reflex. Located in mitochondrial inner membrane. Part of m-AAA complex. Is expressed in central nervous system and sensory organ. Used to study 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Afg3l2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
