Effects of Heparan sulfate acetyl-CoA: Alpha-glucosaminide N-acetyltransferase (HGSNAT) inactivation on the structure and function of epithelial and immune cells of the testis and epididymis and sperm parameters in adult mice.
Integrated modeling of the Nexin-dynein regulatory complex reveals its regulatory mechanism.
Helium is probably not the first thing that comes to mind for most people when they think about recycling – unless they’re experimental chemists working in McGill’s Nuclear Magnetic Resonance (NMR) facilities.
Victoria Glynn, the public program representative from GARM (Graduate Association of the Redpath Museum), has won the prestigious Vanier Scholarship.
Office of Science Education Communications Assistant Brent Jamsa sat down with four students to discuss their upcoming presentations at the second annual Undergraduate Poster Showcase. This year, the highly-anticipated event will be hosted on March 16, 6-8 PM EST via Zoom. Register here to attend: https://mcgill.ca/x/odx.
There are currently three undergraduate research funding opportunities for Summer 2021: SURA, NSERC USRA, and Schull Yang International Experience Awards. These allow students to engage in a full-time summer research activity, and to gain research experience in an exciting academic setting, while receiving financial support. These are open to all B.Sc. and B.A. & Sc. students in the Faculty of Science. For Summer 2021, the Faculty of Science requires all project proposals to include a project the student can start and finish remotely.
Glucose homeostasis and growth essentially depend on the hormone insulin engaging its receptor. Despite biochemical and structural advances, a fundamental contradiction has persisted in the current understanding of insulin ligand–receptor interactions. While biochemistry predicts two distinct insulin binding sites, 1 and 2, recent structural analyses have resolved only site 1. Using a combined approach of cryo-EM and atomistic molecular dynamics simulation, we present the structure of the entire dimeric insulin receptor ectodomain saturated with four insulin molecules.

The telomerase holoenzyme responsible for maintaining telomeres in vertebrates requires many components in vivo, including dyskerin. Dyskerin binds and regulates the accumulation of the human telomerase RNA, hTR, as well as other non-coding RNAs that share the conserved H/ACA box motif. The precise mechanism by which dyskerin controls hTR levels is unknown, but is evidenced by defective hTR accumulation caused by substitutions in dyskerin, that are observed in the X-linked telomere biology disorder dyskeratosis congenita (X-DC).
