Role of the membrane skeleton in preventing the shedding of procoagulant-rich microvesicles from the platelet plasma membrane
J Cell Biol
The platelet plasma membrane is lined by a membrane skeleton that appears to contain short actin filaments cross-linked by actin-binding protein. Actin-binding protein is in turn associated with specific plasma membrane glycoproteins. The aim of this...

Reconstitution of Membrane Proteins into Model Membranes: Seeking Better Ways to Retain Protein Activities
Int J Mol Sci
The function of any given biological membrane is determined largely by the specific set of integral membrane proteins embedded in it, and the peripheral membrane proteins attached to the membrane surface. The activity of these proteins, in turn, can ...
