Hot topic: Cryo-EM structures of Mucolipin TRP Channels in the Lysosome: Five Together at Once

The mucolipin subfamily of Transient Receptor Potential (TRP) channels, which consist of TRPML1, TRPML2, and TRPML3 (a.k.a. MCOLN1- 3), are Ca2+-permeable cation channels localized in intracellular endosomes and lysosomes. In response to cellular stimulation, TRPMLs mediate Ca2+ release from the

Hot topic: A new research avenue investigating mitochondrial GPCR biology

As one of the first propositions for GPCRs being present in mitochondrial membranes, a recent report from Robert Friedlander and colleagues [1] follows on from previous work characterising synaptic and extrasynaptic mitochondria in human cortex (post-mortem samples) and their role

Hot topic: Crystal structure of LPA6, a receptor for lysophosphatidic acid, at 3.2A

Lysophospholipids (LPs) have myriad roles as extracellular signals that activate cognate G protein-coupled receptors (GPCRs) (2). LPs for which receptors have been reported include lysophosphatidic acid (LPA) (receptors: LPA1-6), sphingosine 1-phosphate (S1P1-5), lysophosphatidyl serine (LPS1-3, 2L (2L is a pseudogene

Hot topic: FZD6 dimers dissociate after stimulation – briefly

GPCRs of all classes are widely thought to form homodimers, heterodimers and higher-order oligomers. The functional significance of dimerization is well understood for Class C receptors but less certain for the other GPCR classes, including the rather unconventional class F
