Function

[PPIF_HUMAN] PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Involved in regulation of the mitochondrial permeability transition pore (mPTP). It is proposed that its association with the mPTP is masking a binding site for inhibiting inorganic phosphate (Pi) and promotes the open probablity of the mPTP leading to apoptosis or necrosis; the requirement of the PPIase activity for this function is debated. In cooperation with mitochondrial TP53 is involved in activating oxidative stress-induced necrosis. Involved in modulation of mitochondrial membrane F(1)F(0) ATP synthase activity and regulation of mitochondrial matrix adenine nucleotide levels. Has anti-apoptotic activity independently of mPTP and in cooperation with BCL2 inhibits cytochrome c-dependent apoptosis.^[1] ^[2]

Publication Abstract from PubMed

In the pharmaceutical industry, knowledge of the three-dimensional structure of a specific target facilitates the drug-discovery process. Despite possessing favoured analytical properties such as high purity and monodispersion in light scattering, some proteins are not capable of forming crystals suitable for X-ray analysis. Cyclophilin D, an isoform of cyclophilin that is expressed in the mitochondria, was selected as a drug target for the treatment of cardiac disorders. As the wild-type enzyme defied all attempts at crystallization, protein engineering on the enzyme surface was performed. The K133I mutant gave crystals that diffracted to 1.7 A resolution using in-house X-ray facilities and were suitable for soaking experiments. The crystals were very robust and diffraction was maintained after soaking in 25% DMSO solution: excellent conditions for the rapid analysis of complex structures including crystallographic fragment screening.

Crystal engineering yields crystals of cyclophilin D diffracting to 1.7 A resolution.,Schlatter D, Thoma R, Kung E, Stihle M, Muller F, Borroni E, Cesura A, Hennig M Acta Crystallogr D Biol Crystallogr. 2005 May;61(Pt 5):513-9. Epub 2005, Apr 20. PMID:15858260^[3]
