    Vps8 overexpression inhibits HOPS-dependent trafficking routes by outcompeting Vps41/Lt

    Péter Lőrincz, Lili Anna Kenéz ... Gábor Juhász
    Recruitment of HOPS tethering complex to target membranes to promote vesicle fusions requires proper complex assembly and specific small GTPases, and HOPS is not transformed from the related miniCORVET complex.

    Serial attentional resource allocation during parallel feature value tracking

    Christian Merkel, Luise Burgmann ... Jens-Max Hopf
    The strong limitation of human subjects in tracking two color streams simultaneously as they independently traverse color space can be attributed to attention alternating slowly and sequentially between streams.

    Fusion of tethered membranes can be driven by Sec18/NSF and Sec17/αSNAP without HOPS

    Hongki Song, William T Wickner
    The coordinate activity of Sec17/SNAP and Sec18/NSF for membrane fusion is not limited to systems with homotypic fusion and vacuole protein sorting (HOPS), the lysosomal/vacuolar tethering, and SNARE assembly complex.

    Transcription dynamically patterns the meiotic chromosome-axis interface

    Xiaoji Sun, Lingzhi Huang ... Andreas Hochwagen
    Distributed cohesin rings flexibly tether the axial element structure of meiotic chromosomes to the underlying chromatin to readily accommodate ongoing transcription.

    The multi-subunit GID/CTLH E3 ubiquitin ligase promotes cell proliferation and targets the transcription factor Hbp1 for degradation

    Fabienne Lampert, Diana Stafa ... Matthias Peter
    Proteomic, biochemical and cell-based analyses of the heterodecameric core GID/CTLH E3 ligase complex reveal its molecular architecture, activity determinants, and function in targeting the tumor suppressor Hbp1 and other substrates required for cell proliferation.

    Interplay between charge distribution and DNA in shaping HP1 paralog phase separation and localization

    Tien M Phan, Young C Kim ... Jeetain Mittal
    Despite highly conserved sequences, subtle variations in HP1 paralog charge distribution influence distinct liquid-liquid phase separation behaviors, ultimately impacting DNA-mediated heterochromatin organization.

    An open label randomized controlled trial of tamoxifen combined with amphotericin B and fluconazole for cryptococcal meningitis

    Nguyen Thi Thuy Ngan, Nhat Thanh Hoang Le ... Jeremy N Day
    Despite evidence of significant anti-cryptococcal activity in vitro and animal models, including synergy with other antifungal agents, high-dose tamoxifen has no impact on cerebrospinal fluid sterilization in cryptococcal meningitis.

    Nanoscopic anatomy of dynamic multi-protein complexes at membranes resolved by graphene-induced energy transfer

    Nadia Füllbrunn, Zehao Li ... Changjiang You
    The axial organization and dynamics of the HOPS complex at membrane surface are resolved by graphene-induced energy transfer with subnanometer resolution.

    Sec17 (α-SNAP) and an SM-tethering complex regulate the outcome of SNARE zippering in vitro and in vivo

    Matthew L Schwartz, Daniel P Nickerson ... Alexey J Merz
    Sec17 is shown to have divergent effects on pre-fusion SNARE complex activity, depending on the state of SNARE zippering and HOPS, an SM-tether complex, controls the outcome of Sec17-SNARE engagement.

    Transcription-associated topoisomerase 2α (TOP2A) activity is a major effector of cytotoxicity induced by G-quadruplex ligands

    Madeleine Bossaert, Angélique Pipier ... Dennis Gomez
    Topoisomerase 2α DNA breaks induced by G-quadruplex ligands are associated with a topological stress resulting from a transcription-dependent mechanism and counteracted by DNA topoisomerase 1 and factors promoting transcription elongation.
