Protein
Peptidyl-prolyl cis-trans isomerase FKBP65
Organism
Arabidopsis thaliana
Function
PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Co-chaperone that negatively modulates thermotolerance by interacting with FKBP62 and decreasing the HSFA2-mediated accumulation of chaperones of the small-HSPs family. Plays a positive role in tolerance to intracellular acid stress by maintaining the pH homeostasis. May be a part of transcription regulation pathways upon pathogen infection.
Similarity
Belongs to the FKBP-type PPIase family.
