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.

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.
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.
Distributed cohesin rings flexibly tether the axial element structure of meiotic chromosomes to the underlying chromatin to readily accommodate ongoing transcription.
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.

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.
The axial organization and dynamics of the HOPS complex at membrane surface are resolved by graphene-induced energy transfer with subnanometer resolution.

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.

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.
