    The inner junction complex of the cilia is an interaction hub that involves tubulin post-translational modifications

    Ahmad Abdelzaher Zaki Khalifa, Muneyoshi Ichikawa ... Khanh Huy Bui
    A structure of the ciliary inner junction at 3.6 Å resolution permits atomic modeling of six inner junction proteins and their interactions with acetylated lysine 40 loops of alpha tubulins.

    MICOS coordinates with respiratory complexes and lipids to establish mitochondrial inner membrane architecture

    Jonathan R Friedman, Arnaud Mourier ... Jodi Nunnari
    A conserved mitochondrial inner membrane complex called MICOS works together with the mitochondrial lipid cardiolipin and respiratory complexes to direct the position, copy number and stabilization of cristae structures for efficient respiration.

    Molecular architecture underlying fluid absorption by the developing inner ear

    Keiji Honda, Sung Huhn Kim ... Andrew J Griffith
    Genome-wide RNA-seq analysis of single cells of the developing mouse endolymphatic sac reveals its molecular-cellular architecture and a model for salt and fluid absorption required for acquisition of normal inner ear structure and function.

    Habitat loss weakens the positive relationship between grassland plant richness and above-ground biomass

    Yongzhi Yan, Scott Jarvie, Qing Zhang
    Habitat loss rather than fragmentation per se can weaken the positive BEF relationship by reducing the percentage of grassland specialists in the community.

    Aim24 and MICOS modulate respiratory function, tafazzin-related cardiolipin modification and mitochondrial architecture

    Max Emanuel Harner, Ann-Katrin Unger ... Walter Neupert
    Interactions between Aim24 and the mitochondrial outer and inner membrane contact site complex (MICOS) are essential for mitochondrial ultrastructure, lipid composition and oxidative phosphorylation.

    Oligodendrocyte-encoded Kir4.1 function is required for axonal integrity

    Lucas Schirmer, Wiebke Möbius ... David H Rowitch
    Ultrastructural and loss-of-function experiments show that oligodendrocyte-encoded Kir4.1 is located near active axonal structures, including within myelin inner tongue, and has critical functions to promote axonal activity and preserve integrity.

    Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

    Ian A Swinburne, Kishore R Mosaliganti ... Sean G Megason
    The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.

    QIL1 is a novel mitochondrial protein required for MICOS complex stability and cristae morphology

    Virginia Guarani, Elizabeth M McNeill ... J Wade Harper
    A comprehensive analysis of the human MICOS complex has identified a novel subunit called QIL1 that is required for cristae junction formation in human cells and Drosophila, through its role in the assembly of the MICOS complex.
