'''C domain of human cyclophilin-33(hcyp33)'''<br />


==Overview==
==C domain of human cyclophilin-33(hcyp33)==
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.

== Function ==
[https://www.uniprot.org/uniprot/PPIE_HUMAN PPIE_HUMAN] PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Combines RNA-binding and PPIase activities. May be involved in muscle- and brain-specific processes. May be involved in pre-mRNA splicing.
