    In vivo reconstitution finds multivalent RNA–RNA interactions as drivers of mesh-like condensates

    Weirui Ma, Gang Zhen ... Christine Mayr
    Binding of a multivalent RNA-binding protein to mRNAs that are able to form pervasive RNA–RNA interactions induces formation of mesh-like condensates, whereas binding of mostly structured mRNAs induces sphere-like condensates.

    Cytoneme delivery of Sonic Hedgehog from ligand-producing cells requires Myosin 10 and a Dispatched-BOC/CDON co-receptor complex

    Eric T Hall, Miriam E Dillard ... Stacey K Ogden
    Sonic Hedgehog is transported inside cytonemes with co-receptors that promote contact-mediated signal delivery to initiate rapid, receptor-dependent responses in recipient cells.

    Bardet–Biedl syndrome 3 protein promotes ciliary exit of the signaling protein phospholipase D via the BBSome

    Yan-Xia Liu, Bin Xue ... Zhen-Chuan Fan
    Bardet–Biedl syndrome 3 (BBS3) protein promotes phospholipase D to load onto the BBSome at the ciliary tip for moving out of the cilium via intraflagellar transport.

    Intact synapse structure and function after combined knockout of PTPδ, PTPσ, and LAR

    Javier Emperador-Melero, Giovanni de Nola, Pascal S Kaeser
    Leukocyte common antigen-related receptor protein tyrosine phosphatases (LAR-RPTPs) are precisely localized to synaptic appositions, but do not control the assembly and function of the presynaptic nerve terminal.

    Reformulation of an extant ATPase active site to mimic ancestral GTPase activity reveals a nucleotide base requirement for function

    Taylor B Updegrove, Jailynn Harke ... Kumaran S Ramamurthi
    Reengineering the nucleotide-binding pocket of an extant ATPase to restore ancestral GTPase activity revealed an ATP-dependent intermediate required for function and suggested why the protein evolved to use ATP.

    Anti-ferroptotic mechanism of IL4i1-mediated amino acid metabolism

    Leonie Zeitler, Alessandra Fiore ... Peter J Murray
    IL4i1 is an amino acid oxidase expressed in the mammalian immune system and snake venoms, which control diametrically opposite cell protection versus cell death pathways, respectively.
