Integrins and focal adhesions are a direct link between the ECM and the cytoskeleton. Why would you want this?
Homework Answers
Integrins are heterodimeric principal receptors that act as transmembrane linkers between the extracellular matrix and the actin cytoskeleton. Integrins are proteins found in all animal cells and work alongside with other proteins: cadherins, selectins and syndecans, to mediate cell to cell and cell to matrix interaction. Proteins of integrin family consists of alpha and beta subtypes, which forms the transmembrane heterodimers. Integrins are crucially essential main receptor proteins that cells use to both bind to and respond to the extracellular matrix.
Focal adhesions, or cell-matrix adhesions are dynamic actin-integrin links which are complex plasma membrane-associated large macromolecular assemblies. These dynamic protein complexes form mechanical links between intracellular actin bundles and the extracellular substrate in many types of cells. The focal adhesions plays important role is in the immune system, in which WBCs (white blood cells) migrate along the connective endothelium following cellular signals to damaged biological tissue.

Based on the known function of talin, which of the following would you predict the outcome of genetically deleting talin in platelets, and why? Impaired ability to form blood clots because talin is the key adaptor protein linking the platelet cadherins to the cytoskeleton Impaired ability to form blood clots because tain plays an important role in activating platelet integrins Spontaneous blood clot formation because talin binds to integrin cytoplasmic tails to prevent integrin activation Spontaneous blood clot formation because...

As conclusively as is possible, research has demonstrated that there is no link between autism and vaccines and, yet, people continue to believe the link is present. Why do you think people continue to believe this? If you were talking to someone who holds this belief, what would you say or do? Why?

During the 1960s many high-profile studies purported to show a direct link between cigarette consumption and heart disease. In response to these studies the government began to implement higher cigarette taxes as well as other restrictions that increased the cost of doing business for major cigarette manufacturers. How would you expect supply, demand, and the equilibrium price and quantity to change? O The demand for cigarettes would remain unchanged while supply shifts left. As a result the equilibrium quantity and...

Concave Mirrors "Take first an object in the region between the mirror and focal point. The nearer the object is to the focal point, the weaker the intensity of light will be, but the larger the image will be. The farther away the object is from the focal point (closer to the mirror), the stronger the intensity of light will be, but the smaller the image will be. In both cases the image will be upright." a. verify these statements...

Customers often do not recognize the link between project changes and cost. They may assume that the project contract gives them unlimited rights to suggest or demand any changes after the project was developed, or that the IT solution presented to them is only a working model and subject to modifications.
