  text: Understanding how the activity of membrane receptors and cellular signaling
    pathways shapes cell behavior is of fundamental interest in basic and applied
    research. Reengineering receptors to react to light instead of their cognate ligands
    allows for generating defined signaling inputs with high spatial and temporal
    precision and facilitates the dissection of complex signaling networks. Here,
    we describe fundamental considerations in the design of light-regulated receptor
    tyrosine kinases (Opto-RTKs) and appropriate control experiments. We also introduce
    methods for transient receptor expression in HEK293 cells, quantitative assessment
    of signaling activity in reporter gene assays, semiquantitative assessment of
    (in)activation time courses through Western blot (WB) analysis, and easy to implement
    light stimulation hardware.

  text: "Proteins and their complex dynamic interactions regulate cellular mechanisms
    from sensing and transducing extracellular signals, to mediating genetic responses,
    and sustaining or changing cell morphology. To manipulate these protein-protein
    interactions (PPIs) that govern the behavior and fate of cells, synthetically
    constructed, genetically encoded tools provide the means to precisely target proteins
    of interest (POIs), and control their subcellular localization and activity in
    vitro and in vivo. Ideal synthetic tools react to an orthogonal cue, i.e. a trigger
    that does not activate any other endogenous process, thereby allowing manipulation
    of the POI alone.\r\nIn optogenetics, naturally occurring photosensory domain
    from plants, algae and bacteria are re-purposed and genetically fused to POIs.
    Illumination with light of a specific wavelength triggers a conformational change
    that can mediate PPIs, such as dimerization or oligomerization. By using light
    as a trigger, these tools can be activated with high spatial and temporal precision,
    on subcellular and millisecond scales. Chemogenetic tools consist of protein domains
    that recognize and bind small molecules. By genetic fusion to POIs, these domains
    can mediate PPIs upon addition of their specific ligands, which are often synthetically
    designed to provide highly specific interactions and exhibit good bioavailability.\r\nMost
    optogenetic tools to mediate PPIs are based on well-studied photoreceptors responding
    to red, blue or near-UV light, leaving a striking gap in the green band of the
    visible light spectrum. Among both optogenetic and chemogenetic tools, there is
    an abundance of methods to induce PPIs, but tools to disrupt them require UV illumination,
    rely on covalent linkage and subsequent enzymatic cleavage or initially result
    in protein clustering of unknown stoichiometry.\r\nThis work describes how the
    recently structurally and photochemically characterized green-light responsive
    cobalamin-binding domains (CBDs) from bacterial transcription factors were re-purposed
    to function as a green-light responsive optogenetic tool. In contrast to previously
    engineered optogenetic tools, CBDs do not induce PPI, but rather confer a PPI
    already upon expression, which can be rapidly disrupted by illumination. This
    was employed to mimic inhibition of constitutive activity of a growth factor receptor,
    and successfully implement for cell signalling in mammalian cells and in vivo
    to rescue development in zebrafish. This work further describes the development
    and application of a chemically induced de-dimerizer (CDD) based on a recently
    identified and structurally described bacterial oxyreductase. CDD forms a dimer
    upon expression in absence of its cofactor, the flavin derivative F420. Safety
    and of domain expression and ligand exposure are demonstrated in vitro and in
    vivo in zebrafish. The system is further applied to inhibit cell signalling output
    from a chimeric receptor upon F420 treatment.\r\nCBDs and CDD expand the repertoire
    of synthetic tools by providing novel mechanisms of mediating PPIs, and by recognizing
    previously not utilized cues. In the future, they can readily be combined with
    existing synthetic tools to functionally manipulate PPIs in vitro and in vivo."

  text: "Background\r\nSynaptic vesicles (SVs) are an integral part of the neurotransmission
    machinery, and isolation of SVs from their host neuron is necessary to reveal
    their most fundamental biochemical and functional properties in in vitro assays.
    Isolated SVs from neurons that have been genetically engineered, e.g. to introduce
    genetically encoded indicators, are not readily available but would permit new
    insights into SV structure and function. Furthermore, it is unclear if cultured
    neurons can provide sufficient starting material for SV isolation procedures.\r\n\r\nNew
    method\r\nHere, we demonstrate an efficient ex vivo procedure to obtain functional
    SVs from cultured rat cortical neurons after genetic engineering with a lentivirus.\r\n\r\nResults\r\nWe
    show that ∼108 plated cortical neurons allow isolation of suitable SV amounts
    for functional analysis and imaging. We found that SVs isolated from cultured
    neurons have neurotransmitter uptake comparable to that of SVs isolated from intact
    cortex. Using total internal reflection fluorescence (TIRF) microscopy, we visualized
    an exogenous SV-targeted marker protein and demonstrated the high efficiency of
    SV modification.\r\n\r\nComparison with existing methods\r\nObtaining SVs from
    genetically engineered neurons currently generally requires the availability of
    transgenic animals, which is constrained by technical (e.g. cost and time) and
    biological (e.g. developmental defects and lethality) limitations.\r\n\r\nConclusions\r\nThese
    results demonstrate the modification and isolation of functional SVs using cultured
    neurons and viral transduction. The ability to readily obtain SVs from genetically
    engineered neurons will permit linking in situ studies to in vitro experiments
    in a variety of genetic contexts."

  text: G-protein-coupled receptors (GPCRs) form the largest receptor family, relay
    environmental stimuli to changes in cell behavior and represent prime drug targets.
    Many GPCRs are classified as orphan receptors because of the limited knowledge
    on their ligands and coupling to cellular signaling machineries. Here, we engineer
    a library of 63 chimeric receptors that contain the signaling domains of human
    orphan and understudied GPCRs functionally linked to the light-sensing domain
    of rhodopsin. Upon stimulation with visible light, we identify activation of canonical
    cell signaling pathways, including cAMP-, Ca2+-, MAPK/ERK-, and Rho-dependent
    pathways, downstream of the engineered receptors. For the human pseudogene GPR33,
    we resurrect a signaling function that supports its hypothesized role as a pathogen
    entry site. These results demonstrate that substituting unknown chemical activators
    with a light switch can reveal information about protein function and provide
    an optically controlled protein library for exploring the physiology and therapeutic
    potential of understudied GPCRs.

  text: 'Optogenetik und Photopharmakologie ermöglichen präzise räumliche und zeitliche
    Kontrolle von Proteinwechselwirkung und -funktion in Zellen und Tieren. Optogenetische
    Methoden, die auf grünes Licht ansprechen und zum Trennen von Proteinkomplexen
    geeignet sind, sind nichtweitläufig verfügbar, würden jedoch mehrfarbige Experimente
    zur Beantwortung von biologischen Fragestellungen ermöglichen. Hier demonstrieren
    wir die Verwendung von Cobalamin(Vitamin B12)-bindenden Domänen von bakteriellen
    CarH-Transkriptionsfaktoren zur Grünlicht-induzierten Dissoziation von Rezeptoren.
    Fusioniert mit dem Fibroblasten-W achstumsfaktor-Rezeptor 1 führten diese im Dunkeln
    in kultivierten Zellen zu Signalaktivität durch Oligomerisierung, welche durch
    Beleuchten umgehend aufgehoben wurde. In Zebrafischembryonen, die einen derartigen
    Rezeptor exprimieren, ermöglichte grünes Licht die Kontrolle über abnormale Signalaktivität
    während der Embryonalentwicklung. '

  text: Optogenetics and photopharmacology provide spatiotemporally precise control
    over protein interactions and protein function in cells and animals. Optogenetic
    methods that are sensitive to green light and can be used to break protein complexes
    are not broadly available but would enable multichromatic experiments with previously
    inaccessible biological targets. Herein, we repurposed cobalamin (vitamin B12)
    binding domains of bacterial CarH transcription factors for green-light-induced
    receptor dissociation. In cultured cells, we observed oligomerization-induced
    cell signaling for the fibroblast growth factor receptor 1 fused to cobalamin-binding
    domains in the dark that was rapidly eliminated upon illumination. In zebrafish
    embryos expressing fusion receptors, green light endowed control over aberrant
    fibroblast growth factor signaling during development. Green-light-induced domain
    dissociation and light-inactivated receptors will critically expand the optogenetic
    toolbox for control of biological processes.
