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.

In this diagram of G-protein-coupled receptor activation, the alpha, beta, and gamma subunits are shown with distinct relationships to the plasma membrane. After exchange of GDP with GTP on the ...

Chao Daiyin from the Center of Excellence for Molecular Plant Sciences of the Chinese Academy of Sciences identified a novel protein family ... cell wall and the plasma membrane at the Casparian ...

Lipid anchors on nerve cell membranes stabilize prion protein folding, inhibiting aggregation. Membrane-anchored proteins clump only when exposed to pre-formed protein aggregates, simulating ...

Researchers from the University of Leicester, working with international collaborators, have unraveled a key mechanism by ...

Much of our knowledge of the protein PD-1, a leading cancer treatment target, comes from studies in mice. In a comprehensive assessment of PD-1, researchers have found that PD-1 in mice is ...

Current neuroscience research on plasma membranes mainly focuses on proteins functionality, stability and compartmentalization and rarely ... This radical new way of the regulation of chloride ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

A research team has now used new in vitro and cell culture models to show that a lipid anchor on the outer membrane of nerve cells inhibits the aggregation of the prion protein. Researchers have ...

and the plasma membrane molds around these tubules to form plasmodesmata," said Joshi. "We show that plant proteins MCTP3, 4, and 6 stabilize the nascent plasmodesmata." Joshi and colleagues can ...
