Overview

Uniprot IDO43676
Protein NameNADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 3
Gene NameNDUFB3
OrganismHomo sapiens

Kla Sites from experimental identification

Position Flanking peptide
13 GHEHGHHKMELPDYR
34 TPLETIQKKLAAKGL

Function

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
