BOLA3

Functionⁱ

Acts as a mitochondrial iron-sulfur (Fe-S) cluster assembly factor that facilitates (Fe-S) cluster insertion into a subset of mitochondrial proteins. Probably acts together with NFU1 (PubMed:27532772).By similarity1 Publication

Pathology & Biotechⁱ

Involvement in diseaseⁱ

Multiple mitochondrial dysfunctions syndrome 2 with hyperglycinemia (MMDS2)4 Publications

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

Disease descriptionA severe disorder of systemic energy metabolism, resulting in weakness, respiratory failure, lack of neurologic development, lactic acidosis, hyperglycinemia and early death. Some patients show failure to thrive, pulmonary hypertension, hypotonia and irritability. Biochemical features include severe combined deficiency of the 2-oxoacid dehydrogenases, defective lipoic acid synthesis and reduction in activity of mitochondrial respiratory chain complexes.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:

100%	UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%	UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%	UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
