"The complex recognizes the right vessel, the right place on the cell surface and the right time for the cargo to be delivered. It does that by talking to the membrane fusion protein." More ...

Membrane proteins are proteins found in cell membranes, either at the surface or on intracellular organelles. Integral membrane proteins such as receptors and ion channels span the membrane.

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller ...

A study in the journal Pharmaceuticals has uncovered how specific genetic mutations in α2δ-1 and α2δ-3 proteins linked to ...

Lipid–protein interactions are more numerous and stronger in the split model because the headgroups are free to reorient. When the membrane is reunited, it is expected that the interaction energies ...

JERUSALEM, Jan. 21 (Xinhua) -- Researchers have identified ancient proteins that may help explain how the first complex cells evolved from simpler ones over 1.5 billion years ago, Israel's Ben-Gurion ...

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation. Researchers have demonstrated that a protein complex called the exocyst ...
