    Enzyme activity and selectivity filter stability of ancient TRPM2 channels were simultaneously lost in early vertebrates

    Iordan Iordanov et al.
    Invertebrate TRPM2 channels have stable pores but act as chanzymes that hydrolyze their activating ligand ADP ribose (ADPR), whereas vertebrate TRPM2 channels are catalytically dead but undergo pore inactivation.

    Neurodegenerative disease mutations in TREM2 reveal a functional surface and distinct loss-of-function mechanisms

    Daniel L Kober et al.
    Structural, biophysical, and functional analyses reveal that mutations in TREM2 trigger either misfolding or reduced binding to cell-surface glycosaminoglycans, which segregate with neurodegenerative disease link and highlight a functional surface linked to the pathogenesis of Alzheimer's disease.

    Definition of two agonist types at the mammalian cold-activated channel TRPM8

    Annelies Janssens et al.
    Two natural cooling agents activate the cold-activated channel TRPM8 via two opposite mechanisms, evoking distinct electrical responses in cold-sensitive neurons.

    Sensory Neurons: A new target for G protein signaling

    László Csanády
    G protein-coupled receptor stimulation inhibits TRPM3 channel activity through direct binding of the Gβγ subunit to the channel.

    The ion selectivity filter is not an activation gate in TRPV1-3 channels

    Andrés Jara-Oseguera et al.
    The TRPV1, TRPV2 and TRPV3 channels are gated on the cytosolic side of the pore, whereas structural changes in the ion selectivity filter associated with activation don't control cation access.

    Inhibition of Transient Receptor Potential Melastatin 3 ion channels by G-protein βγ subunits

    Doreen Badheka et al.
    Electrophysiological experiments, Ca2+ imaging, and behavioral studies in mice identify the TRPM3 ion channel as a novel target of G-protein βγ subunits.

    The proposed channel-enzyme transient receptor potential melastatin 2 does not possess ADP ribose hydrolase activity

    Iordan Iordanov et al.
    TRPM2 is simply a ligand gated channel and does not to possess enzymatic activity, even though it shows sequence similarity to Nudix hydrolases.

    Reciprocal regulation among TRPV1 channels and phosphoinositide 3-kinase in response to nerve growth factor

    Anastasiia Stratiievska et al.
    A dual-color TIRFM study reveals a new form of inflammatory regulation, in which a lipid kinase and ion channel reciprocally regulate each other to amplify the response to painful stimuli.

    Hemozoin produced by mammals confers heme tolerance

    Rini H Pek et al.
    Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.
