    Dynamic post-translational modification profiling of Mycobacterium tuberculosis-infected primary macrophages

    Jonathan M Budzik et al.
    Measurement of post-translational modifications in primary macrophages infected with Mtb revealed phosphorylation of TAX1BP1, an autophagy receptor that enables full maturation of the Mtb autophagosome.

    Exploration of CTCF post-translation modifications uncovers Serine-224 phosphorylation by PLK1 at pericentric regions during the G2/M transition

    Brian C Del Rosario et al.
    The chromosome architectural protein, CTCF, is phosphorylated at Ser224 in a cell-cycle-dependent manner and abrogation of phosphorylation leads to a cell growth defect.

    Site-specific phosphorylation and caspase cleavage of GFAP are new markers of Alexander disease severity

    Rachel A Battaglia et al.
    GFAP protein carries a distinct post-translational modification signature that facilitates its pathogenic accumulation and aggregation in astrocytes of patients who succumb to Alexander Disease very early in life.

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

    Ahmad Abdelzaher Zaki Khalifa et al.
    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.

    Cardiac ryanodine receptor distribution is dynamic and changed by auxiliary proteins and post-translational modification

    Parisa Asghari et al.
    Repositioning the type II ryanodine receptors on the sarcoplasmic reticulum membrane is a potential new mechanism regulating their function, and therefore the strength of cardiac contraction.

    The Chd1 chromatin remodeler shifts hexasomes unidirectionally

    Robert F Levendosky et al.
    Oriented hexasomes can be generated using the Widom 601 positioning sequence, which enables straightforward production of nucleosomes with asymmetrically modified H2A/H2B dimers.

    The deca-GX3 proteins Yae1-Lto1 function as adaptors recruiting the ABC protein Rli1 for iron-sulfur cluster insertion

    Viktoria Désirée Paul et al.
    Two newly identified assembly factors for the ribosome-associated iron-sulfur protein Rli1 reveal a general mechanism for how the cytosolic iron-sulfur protein assembly (CIA) machinery recruits apoproteins.

    Evolution-guided functional analyses reveal diverse antiviral specificities encoded by IFIT1 genes in mammals

    Matthew D Daugherty et al.
    Evolutionary innovation and turnover in the IFIT1 antiviral gene family has led to diverse repertoires of antiviral specificity across mammals.

    Specific depletion of the motor protein KIF5B leads to deficits in dendritic transport, synaptic plasticity and memory

    Junjun Zhao et al.
    Two homologous kinesin motors, KIF5A and KIF5B, have distinct functions in dendritic spine morphogenesis, and KIF5B plays a role in synaptic plasticity and memory.
