CALM supports clathrin-coated vesicle completion upon membrane tension increase.

Proc Natl Acad Sci U S A 2021 Jun;118(25)

College of Pharmacy, The Ohio State University, Columbus, OH 43210;

The most represented components of clathrin-coated vesicles (CCVs) are clathrin triskelia and the adaptors clathrin assembly lymphoid myeloid leukemia protein (CALM) and the heterotetrameric complex AP2. Investigation of the dynamics of AP180-amino-terminal-homology (ANTH) recruitment during CCV formation has been hampered by CALM toxicity upon overexpression. We used knock-in gene editing to express a C-terminal-attached fluorescent version of CALM, while preserving its endogenous expression levels, and cutting-edge live-cell microscopy approaches to study CALM recruitment at forming CCVs.

Structure of the endocytic adaptor complex reveals the basis for efficient membrane anchoring during clathrin-mediated endocytosis.

Nat Commun 2021 05 17;12(1):2889. Epub 2021 May 17.

European Molecular Biology Laboratory, Hamburg Outstation, Hamburg, Germany.

During clathrin-mediated endocytosis, a complex and dynamic network of protein-membrane interactions cooperate to achieve membrane invagination. Throughout this process in yeast, endocytic coat adaptors, Sla2 and Ent1, must remain attached to the plasma membrane to transmit force from the actin cytoskeleton required for successful membrane invagination. Here, we present a cryo-EM structure of a 16-mer complex of the ANTH and ENTH membrane-binding domains from Sla2 and Ent1 bound to PIP that constitutes the anchor to the plasma membrane. Read More

Early Life Stress and the Fate of Kynurenine Pathway Metabolites.

Front Hum Neurosci 2021 29;15:636144. Epub 2021 Apr 29.

Contemporary Care, Danbury, CT, United States.

Early life stress (ELS) precedes alterations to neuro-immune activation, which may mediate an increased risk for stress-related psychiatric disorders, potentially through alterations of central kynurenine pathway (KP) metabolites, the latter being relatively unexplored. We hypothesized that ELS in a non-human primate model would lead to a reduction of neuroprotective and increases of neurotoxic KP metabolites. Twelve adult female bonnet macaques reared under conditions of maternal variable foraging demand (VFD) were compared to 27 age- and weight-matched non-VFD-exposed female controls. Read More

Proc Natl Acad Sci U S A 2020 09 24;117(36):22462-22472. Epub 2020 Aug 24.

Department of Molecular Microbiology, School of Medicine, Washington University in St. Louis, St. Louis, MO 63110;

Huntingtin-interacting protein family members are evolutionarily conserved from yeast to humans, and they are known to be key factors in clathrin-mediated endocytosis. Here we identified the protein huntingtin-interacting protein-related 1 (HIPR-1) as a host factor essential for Orsay virus infection of Ablation of HIPR-1 resulted in a greater than 10,000-fold reduction in viral RNA, which could be rescued by ectopic expression of HIPR-1. Viral RNA replication from an endogenous transgene replicon system was not affected by lack of HIPR-1, suggesting that HIPR-1 plays a role during an early, prereplication virus life-cycle stage.
