They catalyze the production of the second messengers inositol-1,4,5-trisphosphate (IP3) and diacylglycerol (DAG) from the hydrolysis of phosphatidylinositol-4,5-bisphosphate (PIP2). These enzymes are activated by G-protein-coupled receptors (GPCRs) through the interaction with the alpha subunit of heterotrimeric G-proteins belonging to the Gq family (Gαq), the Gβγ subunits released by the inhibitory G-protein (Gi) and Ca2+ ions. Here we review current structural insights on these important proteins, with a particular focus on the most structurally characterized isoform (PLC-β3) and the activation mechanism operated by Gαq. We propose, following the lead of recent studies, that a tight combination of experiments and molecular simulations are instrumental in further enlightening the structure/function understanding of PLC-βs. - See more at: http://www.eurekaselect.com/116059/article#sthash.cojH1BB1.dpuf LB - PUB:(DE-HGF)16 ; PUB:(DE-HGF)36 C6 - pmid:24384033 UR - <Go to ISI:>//WOS:000329125100002 DO - DOI:10.2174/13892037113146660085 UR - https://juser.fz-juelich.de/record/201303 ER -
