To respond to environmental conditions, cells must be able to detect extracellular stimuli. One way they do so is through G protein-coupled receptors (GPCRs), receptors that play many roles in signaling processes including smell, taste, sight, inflammation, and ...
Autophagy (Greek for “self-eating”) is a process by which cytoplasmic material, including organelles, are targeted to lysosomes for degradation. Autophagy is a dynamic process which involves autophagosome synthesis, delivery of materials to be degraded to the lysosome, and ...
Kinases: they regulate many proteins, with ~1/3 of human proteins predicted to be phosphorylated on at least one site. Phosphorylation is particularly important for regulating signal transduction and measuring kinase activity at the single-cell level can aid in drawing ...
Addgenie Mary Gearing contributed to the content of this article. Biosensors (‘biological sensors’) are biological tools that monitor a process or detect a given molecule. The sensor component is usually a protein that undergoes a conformational change in response to the ...
Rosella is a pH-sensitive fluorescent biosensor that was recently deposited with Addgene by Dr. Mark Prescott. This system was developed for monitoring and analyzing autophagy of cytosol and organelles in yeast cells. Autophagy (Greek for “self-eating”) is induced by a lack of ...
Epigenetics has recently been hitting the headlines, with sotires like the potential devastation of the palm oil industry through epigenetic effects on the Cover of Nature. So what is epigenetics and what tools are available to study it?
Oliver Griesbeck of the Max Planck Institute for Neurobiology has been working on genetically encoded indicators of calcium and other small molecules since the very beginnings of the field. Those engineered sensors were designed to replace synthetic calcium dyes, which had been ...
