Enables cyclosporin A binding activity; enzyme binding activity; and peptidyl-prolyl cis-trans isomerase activity. Involved in several processes, including protein peptidyl-prolyl isomerization; regulation of mitochondrial membrane potential; and response to oxidative stress. Located in mitochondrion. Orthologous to human PPID (peptidylprolyl isomerase D). [provided by Alliance of Genome Resources, Apr 2022]
