Human immunodeficiency virus type 1 (HIV-1) cDNA synthesis is inhibited in cells from some nonhuman primates by an activity called Lv1. Sensitivity to restriction by Lv1 maps to a region of the HIV-1 CA required for interaction with the cellular protein cyclophilin A. A similar antiviral activity in mammalian cells, Ref1, inhibits reverse transcription of murine leukemia virus (MLV), but only w...
TRIM5α (tripartite motif-containing protein-5, isoform α)-cyclophilin A fusion proteins are anti-human immunodeficiency virus (HIV) restriction factors that have evolved in certain nonhuman primates over millions of years and protect against HIV and related viruses. Restriction by TRIM5αCypA is potent and highly resistant to viral escape by mutation and, in combination with a suitable gene deli...
The accumulation of amyloidogenic proteins is a pathological hallmark of neurodegenerative disorders. The aberrant accumulation of the microtubule associating protein tau (MAPT, tau) into toxic oligomers and amyloid deposits is a primary pathology in tauopathies, the most common of which is Alzheimer's disease (AD). Intrinsically disordered proteins, like tau, are enriched with proline residues...
Cyclophilins are a family of ubiquitous proteins that are the intracellular target of the immunosuppressant drug cyclosporin A. Although cyclophilins catalyze peptidylprolyl cis-trans isomerization in vitro, it has remained open whether they also perform this function in vivo. Here we show that Cpr3p, a cyclophilin in the matrix of yeast mitochondria, accelerates the refolding of a fusion prote...
Cyclophilins (CYP), a member of immunophillin group of proteins, are more often conserved in all genera including plants. Here, we report on the identification of a new cyclophilin gene OsCYP-25 (LOC_Os09 g39780) from rice which found to be upregulated in response to various abiotic stresses viz., salinity, cold, heat and drought. It has an ORF of 540 bp, encoding a protein of 179 amino acids, ...
Coronaviruses infect a variety of mammalian and avian species and cause serious diseases in humans, cats, mice, and birds in the form of severe acute respiratory syndrome (SARS), feline infectious peritonitis (FIP), mouse hepatitis, and avian infectious bronchitis, respectively. No effective vaccine or treatment has been developed for SARS-coronavirus or FIP virus, both of which cause lethal di...
