This post covers three recent publications with a common theme and whose authors are collaborators with GtoPdb, thus making them as a trio particularly suitable for combined review. These are; Discovery of Human Signaling Systems: Pairing Peptides to G Protein-Coupled…

Hot Topics: Virtual screening on the crystal structure of the G protein-coupled melatonin MT1 receptor reveals several new chemical scaffolds with biological activity
Melatonin targets two high-affinity receptors, MT1 and MT2, that belong to the G protein-coupled receptor (GPCR) superfamily (1,2). Drugs acting on melatonin receptors are subscribed for circadian disorders (jet lag, shift work, etc.), insomnia and major depression (3). All marketed…
Hot Topics: Cardiac Ca2+ Channel Regulation in the Fight-or-Flight Response: the monomeric small G-protein as another piece in the puzzle
Thirty eight years after the discovery that injection of the catalytic subunits of cyclic AMP-dependent protein kinase A (PKA) into isolated pig ventricular cardiac myocytes (1) increases the amplitude of L-type Ca2+ current (today known to be formed by Cav1.2…
Hot topics: Cannabinoid receptor stuctures
Two new reports cover further aspects of cannabinoid receptor binding as defined using cryo-EM. These expand on previous reports of the structure of the human CB1 cannabinoid receptor with the antagonists taranabant and AM6538 bound, and with the agonists MDMB-FUBINACA,…
Hot Topics: A brief update on coronaviruses
The new respiratory coronavirus from Wuhan in China is causing intense research activity in the world. Viruses are evidently associated with respiratory infections ranging in severity from the common cold to pneumonia and death

Hot Topics: Cryo-EM structure of a selective T-type calcium channel blocker bound to the Cav3.1 voltage-gated calcium channel
Nieng Yan’s group has now published the cryo-EM structure of the selective T-type Ca2+ channel blocker Z944 bound to the pore-forming α1-subunit of Cav3.1 T-type Ca2+ channels (1). This nicely adds to recent publications reporting of the high-resolution structures of…

Hot Topics: Deciphering the crystal structure of the leukotriene receptor CysLT2 opens up for improved therapeutics
Leukotrienes are lipid mediators of inflammation, initially recognized for their role in asthma, but also having potent effects in for example cardiovascular and neurological diseases as well as in cancer. The initial pharmacological classification of leukotriene receptors based on antagonist…
