as one of the most unfathomable mysteries human beings encounter with, death has always been one of the main concerns of great scholars and one of the major teachings of monotheistic religions. augustine is one of the great scholars who reflect upon and talk about death. interestingly, we do not face with a particular definition of death in augustine’s works. as a platonic philosopher, he consi...

Fyn-related kinase (Frk) was first identified using human breast cancer cells. It shares 51% identity with c-Src. Like all members of the Src family, Frk is thought to cause several cancers via dysregulations in signal transduction from cell-surface receptors. The excess activity of Frk on beta-cells has a crucial role in type-I diabetes. A silent mutation at Ile229 conferred a bacterial expres...

We have expressed recombinant RNase P protein from Escherichia coli in high yield. A hexahistidine sequence at the amino terminus allowed protein purification in a single step. Mass spectrometry confirmed the molecular weight of the purified protein and indicated a purity of > 95%. Protein functionality was demonstrated by reconstitution of active holoenzyme.

Site-specific fluorescent labeling of proteins in vivo remains one of the most powerful techniques for imaging complex processes in live cells. Although fluorescent proteins in many colors are useful tools for tracking expression and localization of fusion proteins in cells, these relatively large tags (>220 aa) can perturb protein folding, trafficking and function. Much smaller genetically enc...

BACKGROUND Making peptide pharmaceuticals involves challenging processes where many barriers, which include production and manufacture, need to be overcome. A non common but interesting research area is related to peptides with intracellular targets, which opens up new possibilities, allowing the modulation of processes occurring within the cell or interference with signaling pathways. However,...
