ATP6 — Brassica juncea

Summary

BJUB03G22560S, symbol ATP6, on Indian mustard (Brassica juncea) chromosome B03, encodes a protein with proton transporter activity and proton-transporting ATP synthase activity, rotational mechanism. The protein belongs to the ATP_synth_Bsub_B/MI25 and MI25_plants domain families and localises to the mitochondrial inner membrane as part of the F1-F0 complex. This gene is associated with mitochondrial gene expression, mitochondrial transcription, proton motive force-driven ATP synthesis, and pollen development. It has also been linked to cytoplasmic male sterility and leaf chlorosis. Related genes in other species, such as ORF25 and ATP6 homologues, are linked to similar mitochondrial functions, though these associations are not yet established in Indian mustard.
