G-protein-coupled receptors (GPCRs) are one of the largest families of cell surface proteins in the human body that recognize hormones, neurotransmitters, and drugs. These receptors regulate a wide ...

A new study found that a single mutation to the hemagglutinin protein of an H5N1 virus isolated from a dairy worker in Texas this spring switched the protein’s binding specificity from avian- to human ...

The SARS-CoV-2 virus is continuously evolving and structural changes to the virus may impact the efficacy of antibody therapies and vaccines. A study describes the structural and functional landscape ...

Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the ...

Researchers created a tool capable of comprehensively mapping crucial interactions underlying drug efficacy in one superfamily of cell receptors. One in every three FDA-approved drugs targets a single ...

The behaviour of a receptor protein can be influenced by the presence of certain lipids in the membrane it is embedded in.

BUFFALO, N.Y. – Touch a hot plate and your hand flies back. While the response is almost instant, researchers are still working to better understand the molecular mechanisms behind these sensations of ...

Lefkowitz started to trace cell receptors in 1968. Using radioactivity, he managed to unveil several receptors, including one for adrenalin, the β-adrenergic receptor. His team then extracted the ...

Drug discovery requires two separate steps: checking whether a drug can bind to a harmful molecule or its receptor, and ...

Up to 20% of hormone receptor-positive breast cancers don't respond to antiestrogen therapies. A study led by researchers at ...
