None:
Venous and arterial identity is predetermined in the embryo, with embryonic vessels expressing Eph-B4 differentiating into veins and vessels expressing ephrin-B2 differentiating into arteries. The specialized membrane organelles lipid rafts and caveolae serve as localized domains for proteins to interact with one another and play a role in signal transduction and vesicular trafficking. Several tyrosine kinase membrane receptors, including Eph-B1, have been colocalized to caveolae. These data suggest that caveolae and Eph receptors may have coordinated roles in determining vessel identity, not only during embryogenesis but perhaps also during adult vascular remodeling and angiogenesis.

The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the anterior...

Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
