Summary: Enables GTPase-dependent fusogenic activity. Involved in several processes, including inner mitochondrial membrane organization; negative regulation of apoptotic signaling pathway; and positive regulation of T-helper 17 cell lineage commitment. Acts upstream of or within neural tube closure. Located in dendrite; mitochondrial inner membrane; and mitochondrial intermembrane space. Is expressed in several structures, including early conceptus; heart; liver; lung; and visual system. Used to study optic atrophy. Human ortholog(s) of this gene implicated in Behr syndrome; dominant optic atrophy plus syndrome; mitochondrial DNA depletion syndrome 14; optic atrophy; and optic atrophy 1. Orthologous to human OPA1 (OPA1 mitochondrial dynamin like GTPase). [provided by Alliance of Genome Resources, Apr 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
