This chapter discusses the structure of the cell membrane. It has been suggested that cell membrane contained either pure lipid or pure protein, with pores about the size of a large molecule, or that it was in the form of a mosaic containing either pure lipid or pure protein in various ...

The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds thecytoplasmof acell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. It also serves as a base of attachmen...

Cytological details of the corneal epithelium were studied with special emphasis on the structure of the cell membrane. Normal corneas of various animals were fixed in a 4% solution of glutaraldehyde and divided into two portions. One-half was frozen with Freon 22 and freeze-fractured in frontal...

The structure provides insight into the architecture of the coat and its mechanism of assembly, and suggests that retromer promotes tubule formation by directing the distribution of sorting nexin proteins on the membrane surface while providing a scaffold for regulatory-protein interactions....
