In plants, members of the UCP family have been associated with several physiological roles, including thermogenesis regulation, abiotic stress responses and climacteric increases in respiration. And some researches show that AtUCP1 responses to abiotic stresses.

Rubisco activase (RCA) is a key photosynthetic protein, it catalyses the activation of Rubisco and thus plays an important role in photosynthesis.

TIC40 is a protein in the chloroplast inner membrane translocon complex. It is involved in protein precursor import into chloroplasts and reinsertion of proteins from the chloroplast stroma into the inner membrane. Three components of the chloroplast protein translocon, Tic110(AT1G06950), Hsp93 (ClpC), and Tic40(AT5G16620), have been shown to be important for protein translocation across the inner envelope membrane into the stroma.

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.

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).
