Ribosome Inactivating Proteins from an evolutionary perspective
Toxicon, 2017Ribosome Inactivating Proteins (RIPs) are rRNA N-glycosidases that inhibit protein synthesis through the elimination of a single adenine residue from 28S rRNA. Many of these toxins have been characterized in depth from a biochemical and molecular point of view.

Recent Progress in Research on Ribosome Inactivating Proteins
Current Protein and Peptide Science, 2009The intent of this article is to review recent literature on ribosome inactivating proteins (RIPs) including isolation and characterization of new RIPs, studies on the crystal structures and mechanisms of actions of RIPs, the use of saporin-based neurotoxins to selectively lesion cholinergic neurons in neuroscience research, and the use of RIP-based ...

Ribosome-Inactivating Proteins in Cereals
2010Plants constitutively accumulate proteins that are either toxic or inhibitory against pathogens, including ribosome-inactivating proteins (RIPs) and N-glycosidases that depurinate the universally conserved α-sarcin loop of large rRNAs. Cereal RIPs share a high similarity with all the other RIPs; however, they retain characteristic features forming a ...

Antiviral Activity Of Ribosome Inactivating Proteins In Medicine
Mini-Reviews in Medicinal Chemistry, 2004Pokeweed antiviral protein and several other ribosome inactivating proteins are effective against a broad range of viruses. Recent results have shown that their enzymatic activity is not limited to depurination of the large rRNA, they can depurinate other nucleic acids, including viral RNAs.

Virus resistance mediated by ribosome inactivating proteins
2000Publisher Summary This chapter describes recent advances in understanding the structure and function of ribosome inactivating proteins (RIPs) and the mechanism of their antiviral activity. RIPs are widely distributed among plants, fungi, and bacteria.

Ribosome inactivating proteins of plants.
Seminars in cell biology, 1992Many plant tissues produce single chain proteins which can enzymatically remove a specific adenine residue from ribosomal RNA. Although these proteins are potently toxic to isolated ribosomes, they are non-toxic to intact cells, being unable to gain access to their ribosomal substrate.

Ribosome-inactivating proteins: From toxins to useful proteins
Toxicon, 2013Ribosome-inactivating proteins (RIPs) either single-chain (type 1) or two-chain (type 2) are frequent in plants, often in multiple forms. They are RNA N-glycosidases, have antiviral, antifungal and insecticidal activity. Their expression in plants is increased under stressful conditions.
