Protein

NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 11, mitochondrial

Gene

NDUFB11

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.

Involvement in diseasei

Linear skin defects with multiple congenital anomalies 3 (LSDMCA3)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA disorder characterized by dermal, ocular, neurological and cardiac abnormalities. LSDMCA3 clinical features include linear skin defects on face and neck at birth, lacrimal duct atresia, myopia, nystagmus, strabismus, cardiomyopathy, axial hypotonia, seizures, corpus callosum agenesis, and dilation of lateral ventricles.

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.
