However, the SK2 immunoparticles were observed within intracellular membranes.

The protein family of annexins has continued to grow since their association with intracellular membranes was first reported in 1977.

They transport their substrates (alpha-tocopherol and phosphatidylinositol or phosphatidylcholine, respectively) between different intracellular membranes.

ABC proteins transport various molecules across extra- and intracellular membranes.

Proteins can be targeted to the inner space of an organelle, different intracellular membranes, plasma membrane, or to exterior of the cell via secretion.

This protein transport primarily different glycosphingolipids and glyceroglycolipids between intracellular membranes, but not phospholipids.

Generally, phosphoinositides transduce signals by recruiting specific phosphoinositide-binding proteins to intracellular membranes.

These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes.

While not typical of all bacteria some microbes contain intracellular membranes in addition to (or as extensions of) their cytoplasmic membranes.

Production of the capsid happens at the surface of intracellular membranes simultaneously with the budding of the virus.
