== Publication Abstract from PubMed ==

Cyclophilins (CyPs) are a widespreading protein family in living organisms and possess the activity of peptidyl-prolyl cis-trans isomerase (PPIase), which is inhibited by cyclosporin A (CsA). The human nuclear cyclophilin (hCyP33) is the first protein which was found to contain two RNA binding domains at the amino-terminus and a PPIase domain at the carboxyl-terminus. We isolated the hCyP33 gene from the human hematopoietic stem/progenitor cells and expressed it in Escherichia coli, and determined the crystal structure of the C domain of hCyP33 at 1.88 A resolution. The core structure is a beta-barrel covered by two alpha-helices. Superposition of the structure of the C domain of hCyP33 with the structure of CypA suggests that the C domain contains PPIase active site which binds to CsA. Furthermore, C domain seems to be able to bind with the Gag-encoded capsid (CA) of HIV-1 and may affect the viral replication of HIV-1. A key residue of the active site is changed from Ala-103-CypA to Ser-239-hCyP33, which may affect the PPIase domain/substrates interactions.
