The 19 Wnt proteins found in humans are part of a larger superfamily of proteins that are also found in Archaea and Bacteria.

Being abundant primary producers, single-celled eukaryotic diatoms and dinoflagellates dominate marine food webs and significantly impact the ecology of the oceans. These organisms face competition ...

Researchers at University of California San Diego have identified a new signaling process involving G protein-coupled receptors (GPCRs), a cellular target already exploited by hundreds of diverse ...

Galanin is a biologically active neuropeptide, and functions through three distinct G protein–coupled receptors (GPCRs), namely GALR1, GALR2, and GALR3. GALR signaling plays important roles in ...

In the march of metastasis, a molecular trail of crumbs guides some cancer cells from the primary tumor to establish new ...

G protein-coupled receptors (GPCRs) are transmembrane proteins that transduce an extracellular signal—ligand binding—into an intracellular signal—activation of G-protein—which in turn activates ...

Animals depend on their sense of smell to locate food, identify mates and evade danger. In mammals, olfactory perception typically relies on G protein–coupled receptor (GPCR) pathways. Insects, by ...

Researchers have developed a new tool to better understand how chemicals like dopamine and epinephrine interact with neurons. University of Michigan researchers have developed a new tool to better ...
