ESCRT-III heteropolymers utilize non-specific lateral electrostatic interactions to recognize one another, which may enable the polymers to slide along one another and adapt to different curvatures.
Theoretical scenario for prebiotic polymers capable of nonenzymatic replication to acquire an early catalytic function, specifically cleavage activity.
Electron microscopy on native membranes reveals the shape and potential function of protein machinery responsible for budding vesicles and viruses away from the cytoplasm.
Laterally associating specific ESCRT-III subunits can replace one another with simple modifications, providing insights into the design principles of ESCRT-III heteropolymerization.

Post-phosphoryl modification of α-dystroglycan requires the glucuronyltransferase B4GAT1; this enzyme synthesizes the acceptor glycan that serves as a primer for the glycosyltransferase LARGE to synthesize the laminin-binding glycan.

Mycobacteria employ plasma membrane compartments to organize their cell wall synthesis, and the finalized cell wall compartmentalizes the plasma membrane to promote an environment conducive to its own synthesis.
