Function

Catalyzes the transfer of a malonyl moiety from malonyl-CoA to the free thiol group of the phosphopantetheine arm of the mitochondrial ACP protein (NDUFAB1) (PubMed:12882974, PubMed:19549604). This suggests the existence of the biosynthesis of fatty acids in mitochondria (PubMed:12882974). Also acts as a mitochondrial small ribosomal subunit (mt-SSU) assembly factor (PubMed:36482135).

Involvement in disease

Optic atrophy 15

OPA15

A disease characterized by visual impairment in association with optic atrophy. Atrophy of the optic disk indicates a deficiency in the number of nerve fibers which arise in the retina and converge to form the optic disk, optic nerve, optic chiasm and optic tracts. OPA15 is an autosomal recessive form.

None

The disease is caused by variants affecting the gene represented in this entry.

Pathway

Lipid metabolism; fatty acid biosynthesis.
