overview
Our lab investigates the molecular mechanism of protein transport across: (i) the nuclear envelope via the nuclear pore complex (NPC); and (ii) the bacterial cytoplasmic membrane via the Sec(retion) and Tat (twin-arginine translocation) machineries. We seek to understand how large molecules such as proteins are transported across biological membranes without leakage.
