    A model for regulation by SynGAP-α1 of binding of synaptic proteins to PDZ-domain 'Slots' in the postsynaptic density

    Ward G Walkup IV, Tara L Mastro ... Mary B Kennedy
    The α1 isoform of synGAP restricts the binding of AMPA-receptors and other regulatory proteins to PSD-95, and thus regulates synaptic strength.

    Naa12 compensates for Naa10 in mice in the amino-terminal acetylation pathway

    Hyae Yon Kweon, Mi-Ni Lee ... Gholson J Lyon
    Mice doubly deficient for Naa10 and Naa12 display embryonic lethality, with both enzymes compensating for each other with amino-terminal acetylation of proteins in mouse development.

    ARL13B regulates Sonic hedgehog signaling from outside primary cilia

    Eduardo D Gigante, Megan R Taylor ... Tamara Caspary
    ARL13B regulates cell ciliation and cilia length from within cilia and Sonic hedgehog response from outside of cilia indicating the two processes can be spatially uncoupled.

    A transient role of the ciliary gene Inpp5e in controlling direct versus indirect neurogenesis in cortical development

    Kerstin Hasenpusch-Theil, Christine Laclef ... Thomas Theil
    Primary-cilia-mediated processing of the Gli3 transcription factor enables the formation of subtypes of projection neurons in appropriate numbers during the development of the cerebral cortex.

    Antibiotic-induced acceleration of type 1 diabetes alters maturation of innate intestinal immunity

    Xue-Song Zhang, Jackie Li ... Martin J Blaser
    Alteration of host gut microbiota by antibiotic exposure in early life remodeled host intestinal immune development and metabolism and enhanced the induction of type 1 diabetes in genetically predisposed animals.

    PI3K/Akt1 signalling specifies foregut precursors by generating regionalized extra-cellular matrix

    S Nahuel Villegas, Michaela Rothová ... Joshua M Brickman
    A signalling cascade involving PI3K/Akt1 remodels the extra-cellular matrix to achieve atypical cellular responses and control cell fate specification within the embryonic endoderm.

    Endogenous Syngap1 alpha splice forms promote cognitive function and seizure protection

    Murat Kilinc, Vineet Arora ... Gavin Rumbaugh
    Alternatively spliced C-terminal protein sequences encoded by the Syngap1 gene exhibit unique biochemical and functional properties in vivo, which explain in part how individual isoforms can promote cognitive functions and seizure protection.

    Pancreatic tumors exhibit myeloid-driven amino acid stress and upregulate arginine biosynthesis

    Juan J Apiz Saab, Lindsey N Dzierozynski ... Alexander Muir
    Analysis of the tumor microenvironment reveals that pancreatic tumors experience metabolic stress caused by immune cell degradation of the amino acid arginine, and that pancreatic cancers cope by synthesizing arginine to provide access this amino acid despite low tumor availability.

    A missense in HSF2BP causing primary ovarian insufficiency affects meiotic recombination by its novel interactor C19ORF57/BRME1

    Natalia Felipe-Medina, Sandrine Caburet ... Alberto M Pendás
    Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.
