Background: Annexin A6
The Annexins comprise a family of proteins that are involved in many aspects of cellular membrane dynamics and the regulation of membrane-associated proteins. They are characterized by multiple repeats of 60 - 70 amino acids (aa) which assemble into a curved disc-like domain that binds to membrane phospholipids in a calcium-dependent manner (1). Human Annexin A6, also known as Annexin VI, Lipocortin VI, and Chromobindin 20, is a 68 kDa protein that consists of eight tandem annexin repeats (2). Alternate splicing results in the deletion of 6 aa at the start of the seventh repeat (3). Human Annexin A6 shares 95% aa sequence identity with mouse and rat Annexin A6. Within the cell, Annexin A6 is involved in the regulation of membrane vesicle trafficking and chloride and calcium ion conductance (1, 4). Annexin A6 is also secreted into the bile and is present on the cell surface (5 - 7). Annexin A6 binds to chondroitin sulfate in a calcium-dependent manner and to heparan sulfate independently of calcium (6, 8). These interactions enable cell surface Annexin A6 to mediate adhesion such as that between macrophages and hepatic sinusoidal endothelial cells (6, 7).
