Ribosome inactivating proteins and apoptosis
Ribosome inactivating proteins (RIPs) are protein toxins that are of plant or microbial origin that inhibit protein synthesis by inactivating ribosomes. Recent studies suggest that RIPs are also capable of inducing cell death by apoptosis. Though many reports are available on cell death induced by RIPs, the mechanism involved is not well studied ...

Ribosome inactivating proteins from plants inhibiting viruses. [PDF]
Many plants contain ribosome inactivating proteins (RIPs) with N-glycosidase activity, which depurinate large ribosomal RNA and arrest protein synthesis. RIPs so far tested inhibit replication of mRNA as well as DNA viruses and these proteins, isolated from plants, are found to be effective against a broad range of viruses such as human ...

Ribosome‐inactivating proteins up to date
Ribosome‐inactivating proteins (RIPs) from plants inactivate eukaryotic ribosomes, as far as studied by rendering their 60 S subunit unable to bind elongation factor 2. These proteins seem widely distributed and possibly ubiquitous in plants. They are either type 1, those consisting of a single polypeptide chain, or type 2 (ricin and related toxins ...

Membrane fusion mediated by ricin and viscumin [PDF]
The ribosome inactivating plant proteins (RIPs) ricin and viscumin but not Ricinus communis agglutinin are able induce vesicle–vesicle fusion. A model is suggested in which the toxicity of the RIPs is partially determined by their fusogenicity.

Viruses and the cellular RNA decay machinery. [PDF]
The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

Bioactive proteins and peptides isolated from Chinese medicines with pharmaceutical potential. [PDF]
Some protein pharmaceuticals from Chinese medicine have been developed to treat cardiovascular diseases, genetic diseases, and cancer. Bioactive proteins with various pharmacological properties have been successfully isolated from animals such as Hirudo ...

Dianthin and Its Potential in Targeted Tumor Therapies [PDF]
Dianthin enzymes belong to ribosome-inactivating proteins (RIPs) of type 1, i.e., they only consist of a catalytic domain and do not have a cell binding moiety.

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Lectin domains at the frontiers of plant defense [PDF]
Plants are under constant attack from pathogens and herbivorous insects. To protect and defend themselves, plants evolved a multi-layered surveillance system, known as the innate immune system.

EIF1AX Nucleolar Condensates Enhance Susceptibilities for the Management of Endometrial Cancer
This schematic illustrates the mechanism of a senolytic strategy in endometrial cancer. EIF1AX facilitates the incorporation of DDX21 into nucleolar condensates, an event that suppresses rDNA transcription and induces cellular senescence. The compound 2,5‐MeC exploits this pathway by promoting EIF1AX nucleolar translocation and condensate formation ...
