Signal peptide-regulated toxicity of a plant ribosome-inactivating protein during cell stress.

Marshall RS, D’Avila F, Di Cola A, Traini R, Spano L, Fabbrini MS, Ceriotti A (2011) Signal peptide-regulated toxicity of a plant ribosome-inactivating protein during cell stress. Plant J 65(2):218-29. doi: 10.1111/j.1365-313X.2010.04413.x

Summary: Type I ribosome inactivating proteins (RIPs) are thought to have a role in defending plants against viral or fungal infections. Most type I RIPs have signal peptides for insertion into the endoplasmic reticulum, followed by transportation to a vacuole or the cell wall. The authors examined signal peptide regulation under stress in tobacco plants transfected with saporin. One method of analysis was western blots using anti-saporin (Cat. #AB-15).
