    Global alignment and assessment of TRP channel transmembrane domain structures to explore functional mechanisms

    Katherine E Huffer, Antoniya A Aleksandrova ... Kenton J Swartz
    Structure-based alignment of TRP channels enables comparison of structural changes, ion permeation pathways and ligand-binding sites and reveals over-representation of structures that represent non-conducting states.

    Mimicry can drive convergence in structural and light transmission features of transparent wings in Lepidoptera

    Charline Sophie Pinna, Maëlle Vilbert ... Marianne Elias
    Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.

    Neural structure mapping in human probabilistic reward learning

    Fabrice Luyckx, Hamed Nili ... Christopher Summerfield
    During learning, human neural codes for experienced reward probability map onto the same mental number line for symbolic numbers.

    Sequence and structural conservation reveal fingerprint residues in TRP channels

    Deny Cabezas-Bratesco, Francisco A Mcgee ... Sebastian E Brauchi
    Joint sequence, structure, and phylogenetic analyses identify highly conserved features in transmembrane domains of transient receptor potential (TRP) ion channel proteins that offer a novel explanation for how TRPs could integrate stimuli into cellular signals.

    Structural and regulatory insights into the glideosome-associated connector from Toxoplasma gondii

    Amit Kumar, Oscar Vadas ... Stephen Matthews
    The glideosome-associated connector protein transitions between open and closed states, and this regulates its assembly and function during apicomplexan parasite motility.

    The prolactin receptor scaffolds Janus kinase 2 via co-structure formation with phosphoinositide-4,5-bisphosphate

    Raul Araya-Secchi, Katrine Bugge ... Birthe B Kragelund
    The prolactin receptor, Janus kinase 2, and PI(4,5)P2 form a co-structure with the membrane resulting in orientations with different accessibility fixing the disordered juxtamembrane domain of the receptor in an extended structure.
