    Temporal transcriptional response of Candida glabrata during macrophage infection reveals a multifaceted transcriptional regulator CgXbp1 important for macrophage response and fluconazole resistance

    Maruti Nandan Rai, Qing Lan ... Koon Ho Wong
    The dynamic transcription responses of the human fungal pathogen Candida glabrata during macrophage infection is revealed and a novel transcription factor important for the responses to macrophage, proliferation within macrophage, as well as anti-fungal drug resistance has been discovered.

    Ctf4 organizes sister replisomes and Pol α into a replication factory

    Zuanning Yuan, Roxana Georgescu ... Huilin Li
    Eukaryotic replisomes are strongly connected together to replicate both sister DNAs produced from a bidirectional origin.

    Post-meiotic DNA double-strand breaks occur in Tetrahymena, and require Topoisomerase II and Spo11

    Takahiko Akematsu, Yasuhiro Fukuda ... Josef Loidl
    The first genetic compelling evidence for post-meiotic DNA double-strand breaks and its relation to chromatin remodeling in haploid pronuclei is shown.

    Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

    Cecilia Lövkvist, Pawel Mikulski ... Martin Howard
    Extra protein memory storage elements with positive feedbacks, in addition to histone modifications, can explain epigenetic switching and memory at the PRC2 target gene FLOWERING LOCUS C (FLC).

    HP1α is a chromatin crosslinker that controls nuclear and mitotic chromosome mechanics

    Amy R Strom, Ronald J Biggs ... Andrew D Stephens
    Micromanipulation experiments demonstrate that HP1α strengthens interphase and mitotic chromosome mechanics and maintains nuclear shape by chromatin crosslinking, separate from histone methylation.

    DNA-mediated association of two histone-bound complexes of yeast Chromatin Assembly Factor-1 (CAF-1) drives tetrasome assembly in the wake of DNA replication

    Francesca Mattiroli, Yajie Gu ... Karolin Luger
    After DNA replication, nucleosomes are assembled by two histone chaperone complexes each bound to an H3-H4 histone dimer, suggesting the feasibility for a semi-conservative mode of epigenome inheritance.

    Systematic analysis of the molecular and biophysical properties of key DNA damage response factors

    Joshua R Heyza, Mariia Mikhova ... Jens C Schmidt
    Live-cell single-molecule imaging of DNA repair factors can be used to analyze their localization to DNA lesions and dissect the hierarchy of their recruitment.

    Insights into the molecular architecture and histone H3-H4 deposition mechanism of yeast Chromatin assembly factor 1

    Paul Victor Sauer, Jennifer Timm ... Daniel Panne
    The CAF1 complex binds single histone H3-H4 dimers, and two such complexes associate with extended DNA elements to ensure the deposition of H3-H4 tetramers, the first step in the assembly of nucleosomes.

    Modular UBE2H-CTLH E2-E3 complexes regulate erythroid maturation

    Dawafuti Sherpa, Judith Mueller ... Arno F Alpi
    Erythroid maturation-dependent remodelling of CTLH E3 complex, along with its cognate E2, controls the orderly progression of human erythropoiesis, thus establishing a paradigm for other E2-E3 ubiquitylation modules involved in developmental processes.
