Osteoblasts secrete the osteoid into this membrane to form a spongelike network of bony processes called trabeculae.
The p7 protein of the hepatitis C virus (HCV) can oligomerize in membrane to form cation channels.
These polyelectrolytes were mixed with poly ethylene oxide) PEO into a composite membrane to form solid electrolytes for lithium batteries.
Besteiro, S., Michelin, A., Poncet, J., Dubremetz, J. F. & Lebrun, M. Export of a Toxoplasma gondii rhoptry neck protein complex at the host cell membrane to form the moving junction during invasion.
Clathrin-mediated or receptor-mediated endocytosis is a multi-step process, whereby membrane-localized proteins are engulfed as cargo in clathrin-coated pits, which then bud off the membrane to form the early endosome.
After the nuclear divisions are complete, the cytoplasm separates, and each nucleus becomes encased in its own membrane to form an individual cell.
The antibiotic is known to interact with sterols present in the cell membrane to form ion channels that disrupt membrane function.
We propose that this pore assembles in the outer membrane to form the opening through which the monomer chains exit the cell.
For example, in some cells, actin filaments are bundled by accessory proteins, and the bundle is attached to the cell membrane to form microvilli, stable protrusions that resemble tiny bristles.
Part of the contents of the granules merge with the vitelline membrane to form the fertilization membrane; if fusion of the contents of the cortical granules with the vitelline membrane is prevented, the membrane remains thin and soft.
Thus connected, the subunits push up through the cell membrane to form a strong, stable fiber, the team reports in the 15 November issue of Cell.
