CXCL13, a signaling protein that is produced immediately after infection with B. burgdorferi and triggers an immune response, could provide a more accurate diagnosis—if it were known at what ...

Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth ...

but they are more similar in amino acid sequences that interact with common intracellular signaling proteins. Protein families may have many members, and they likely evolved from ancient gene ...

In a recent study, a team of researchers led by Dr. Naoki Yamaji, from the Institute of Plant Science and Resources, Okayama University, Japan, has uncovered a key signaling protein, Shoot-Silicon ...

A new study shows how an anticancer drug triggers an “outside in” signal that gets it sucked into a cancer cell. The work, published Jan. 29 in Nature Communications, reveals a new signaling mechanism ...
