    An unexpected INAD PDZ tandem-mediated plcβ binding in Drosophila photo receptors

    Fei Ye et al.
    Biochemical and structural studies uncover an unexpected mode of interaction, with unprecedented high affinity, between INAD scaffold and NORPA that is critical for Drosophila compound eye photo-transduction.

    A gonad-expressed opsin mediates light-induced spawning in the jellyfish Clytia

    Gonzalo Quiroga Artigas et al.
    Gamete release in the jellyfish Clytia is mediated by an opsin photopigment expressed in neurosecretory cells of the gonad ectoderm, which release an oocyte maturation hormone in response to light.

    Blue light-induced LOV domain dimerization enhances the affinity of Aureochrome 1a for its target DNA sequence

    Udo Heintz, Ilme Schlichting
    Light absorption by the algal transcription factor Aureochrome 1a causes dimerization at the light-oxygen-voltage (LOV) sensing domain, which has implications for the design of synthetic photoreceptors for optogenetics.

    The formation of the light-sensing compartment of cone photoreceptors coincides with a transcriptional switch

    Janine M Daum et al.
    Correlating changes in structure and gene expression in cone photoreceptors of mice daily, between birth and eye opening, created a resource that supports research in photoreceptor function, development, transplantation and repair.

    The β-alanine transporter BalaT is required for visual neurotransmission in Drosophila

    Yongchao Han et al.
    BalaT-dependent β-alanine trafficking pathway in retinal pigment cells is critical for maintaining synaptic transmission of photoreceptor neurons in Drosophila.

    Light-dependent pathways for dopaminergic amacrine cell development and function

    Teona Munteanu et al.
    Rods, not ipRGCs, are the major retinal photoreceptor impacting development of dopaminergic signaling in the retina.

    Rhodopsin targeted transcriptional silencing by DNA-binding

    Salvatore Botta et al.
    Photoreceptor genomic binding of a 20 base-pair-long DNA sequence by a synthetic DNA-binding protein turns off Rhodopsin expression.

    Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis

    Ashutosh Pudasaini et al.
    In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.
