Understanding the APJ Receptor Binding Site

(PhysOrg.com) -- Apelin is a recently discovered peptide that binds to the apelin (or APJ) G-protein-coupled receptor. Apelin-13 (NH2-QRPRLSHKGPMPF-COOH), one of several cleavage products of the proprotein form of the apelin ...

How does body temperature reset the biological clock?

Numerous processes in our body fluctuate in a regular pattern during the day. These circadian (or daily) variations can be driven by local oscillators present within our cells or by systemic signals controlled by the master ...
