AT1G51980 / Anti-Probable mitochondrial-processing peptidase subunit alpha-1, mitochondrial antibody
Mitochondrial ubiquinol-cytochrome c oxidoreductase is also called complex III and it accepts electron from quinol and transferred to cytochrome c. In Arabidopsis mitochondria, ubiquinol-cytochrome c oxidoreductase contains 10 subunits. MPP alpha (AT1G51980) is one of the subunit of Complex III.
PHB1 / Anti-Prohibitin-1, mitochondrial antibody
Prohibitins (PHBs) are highly conserved proteins belonging to the large SPFH (stomatin, prohibitin, flotillin and HflKC) superfamily. The PHB family of proteins includes two members, termed prohibitin 1 (PHB1)(AT4G28510) and prohibitin 2 (PHB2)(AT1G03860). Both proteins are highly homologous and interdependent: disruption of one homolog results in the destabilization and rapid degradation of the other. Most genomes contain two PHB genes (for PHB1 and PHB2, respectively).
