When a signaling molecule joins with an appropriate receptor on a cell surface, this binding triggers a chain of events that not only carries the signal to the cell interior, but amplifies it as well.

A new study published in Biochemistry sheds light on how bacteria regulate their genes, challenging long-held assumptions ...

cGMP is found in many human organs and regulates numerous body functions. Interestingly, the signaling molecule may be formed in the vascular cells in several different ways. "Because the overall ...

Bacteria respond to this danger signal by producing a small signaling molecule known as c-di-GMP, which triggers biofilm formation. Biofilms are complex, three-dimensional structures of living ...

A new study led by Dr. Rodrigo Maillard at Georgetown University, “Identifying Allosteric Hotspots in Mycobacterium tuberculosis cAMP Receptor Protein through Structural Homology,” published in ...
