2026 Membrane Transport Proteins Gordon Research Conference and Gordon Research Seminar - PROJECT SUMMARY The 2026 Gordon Research Conference on Membrane Transport Proteins, “The Dynamic Membrane Transporter: Gateways to Health & Disease,” will convene ~200 investigators from academia, industry, and medicine at the Renaissance Tuscany Il Ciocco, June 14–19 (trainee-led GRS, June 13–14). This location facilitates participation by a broad international community of scientist, trainees, and early-career scientists working on membrane transport proteins. The broader scientific exchange directly benefits public health in the United States by speeding advances in the understanding of disease mechanisms, the development of new drugs, and the identification of promising therapeutic strategies. It also ensures that the United States researchers remain fully engaged with the discoveries, technologies, and research shaping drug discovery in this important field. Membrane transporters comprise roughly 10 % of the human genome, yet fewer than 4 % are clinically exploited, despite their central roles in prevalent disorders, including autism, depression, ADHD, addiction, and diabetes, and in rare diseases such as Christianson syndrome and mucoviscidosis. Breakthroughs in cryo-EM, AI-driven structure prediction, live-cell biosensors, and human-derived disease models now make it possible to translate fundamental transporter biology into first-in-class therapeutics, creating a timely need for a forum that seamlessly links molecular mechanisms to clinical applications. The program’s nine themed sessions and two plenary lectures deliberately pair structural and mechanistic discoveries with preclinical and clinical perspectives, covering topics from vesicular neurotransmitter loading and blood–brain-barrier gateways to ABC/OCT1-mediated drug disposition. Interwoven “Technology Spotlight” talks and “Reality-Check” panels will showcase state-of-the-art methods while candidly addressing their limitations, establishing rigorous, field-wide standards. A 1.5-day, trainee-run Gordon Research Seminar, anchored by keynote mentors Drs. Sara Jones and Walter Boron, plus mentoring innovations such as “Scientist Speed-Dating” lunches and the forum Breaking the Mold: Overcoming Barriers to Career Advancement will foster an inclusive, supportive environment that cultivates the next generation of transporter scientists. Guided by three specific aims, catalyzing translational science, elevating rigor and reproducibility, and building a global workforce, the conference is poised to reveal new transporter ligands, biomarkers, and drug-delivery strategies; to disseminate best-practice methodologies; and to launch enduring mentorship networks. By uniting siloed disciplines in a confidential, off-the-record environment that encourages presentation of unpublished data, the 2026 GRC will accelerate transporter-based solutions for some of today’s most urgent unmet medical needs.
