atp8 — Daucus carota subsp. sativus

Summary

DCAR_032428 (atp8, also known as orfB-CMS) on carrot chromosome Mt encodes a YMF19-like protein with ATP-binding activity and EC 7.1.2.2, as part of the F1-F0 complex in the mitochondrial membrane. The gene is associated with ATP anabolism and proton transmembrane transport. It is also associated with cytoplasmic male sterility. Studies of related genes in other species, such as the OrfB protein and YMF19, further connect the family to mitochondrial function and male sterility, though these associations are not yet established for carrot itself.
