intracellular membranes

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

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

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

However, the SK2 immunoparticles were observed within intracellular membranes.

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

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

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

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

RhoV/Chp depends on palmitoylation rather than prenylation for association with plasma and intracellular membranes.

Examples of bacteria containing intracellular membranes are phototrophs, nitrifying bacteria and methane-oxidising bacteria.

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

They transport a wide variety of substrates across extra- and intracellular membranes, including metabolic products, lipids and sterols, and drugs.

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

Glycolipid transfer protein is a cytosolic protein that catalyses the transfer of glycolipids between different intracellular membranes.

Thus, not only is the unique sα i2 sequence unable to override other localization signals, it is unable to target a cytoplasmic protein to intracellular membranes.

In this type of cell fusion polyethylene glycol, PEG, acts as a dehydrating agent and fuses not only plasma membranes but also intracellular membranes.

It appears from experiments in which platelet-membrane fractions have been separated that thromboxane synthesis is associated with intracellular membranes known as dense tubular membranes (Carey et al, 1982).

All therapeutically effective PDE inhibitors must be incorporated into the cell because all PDEs are localized in the cytoplasm and/or on intracellular membranes.

A splice variant of α i2 , termed sα i2 , has been proposed as a candidate to regulate vesicle transport due to its localization at intracellular membranes.

Membranous organelles (a.k.a. intracellular membranes) are known in some groups of prokaryotes, such as vacuoles or membrane systems devoted to special metabolic properties, e.g., photosynthesis or chemolithotrophy.

P-gp is a well-characterized ABC-transporter (which transports a wide variety of substrates across extra- and intracellular membranes) of the MDR/TAP subfamily.

The regulation of SREBP cleavage employs a notable feature of eukaryotic cells, subcellular compartmentalization defined by intracellular membranes, to ensure that cleavage occurs only when needed.

An amino terminal, calcium-dependent lipid binding (CaLB or C2) domain regulates Ca 2+-mediated cPLA 2 translocation to intracellular membranes [ 9 ] .

Thus, the second possibility is that failure of sα i2 to localize at the PM but instead localize at intracellular membranes is the result of a general defect in protein stability.

Intracellular membranes are also found in bacteria belonging to the poorly studied Planctomycetes group, although these membranes more closely resemble organellar membranes in eukaryotes and are currently of unknown function.
