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.
Mitochondrial F0F1-ATP synthase is also called Complex V and it synthesis ATP from ADP and Pi using the proton motive force created by respiratory electron transport. ATP5 (AT5G13450) is a subunit of mitochondrial F0F1-ATP synthase in Arabidopsis.
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.
