A decoy is usually a person, device or event meant as a distraction to conceal what an individual or a group might be looking for. Decoys have been used for centuries most notably in game hunting, but also in wartime and in the committing or resolving of crimes. Image File history File links Question_book-3. ...

For a defence system, decoys and chaff for ICBMs would mainly work in midcourse: during the boost phase they would be inside the rocket, because separate rockets for each of many decoys would not be practical, while at reentry light decoys and chaff considerably slow down and/or are destroyed in the atmosphere.

A decoy was originally a small pond with a long cone-shaped wickerwork tunnel, used to catch wild ducks. After the ducks settled, a small trained dog would herd the ducks into the tunnel. The catch was formerly sent to market for food, but now these are only used to catch ducks to be ringed and released: see ornithology. The word came from Dutch eende(n)kooi = "duck cage". As the above meaning of a person or device supplanted the original meaning as the most common, the latter acquired the retronym "decoy pool".

Wildfowl decoys (primarily ducks, geese, shorebirds, and crows, but including some other species) are considered a form of folk art. Collecting decoys has become a significant hobby both for folk art collectors and hunters.

In biochemistry

In biochemistry, there are decoy receptors, decoy substrates and decoy RNA. In addition, digital decoys are used in protein folding simulations. In biochemistry, a receptor is a protein on the cell membrane or within the cytoplasm or cell nucleus that binds to a specific molecule (a ligand), such as a neurotransmitter, hormone, or other substance, and initiates the cellular response to the ligand. ... Ribonucleic acid (RNA) is a nucleic acid consisting of a string of covalently-bound nucleotides. ... Protein before and after folding. ...


Decoy receptor

A decoy receptor, or sink receptor [2], is a receptor that binds a ligand, inhibiting it from binding to its normal receptor. For instance, the receptor VEGFR-1 can prevent vascular endothelial growth factor (VEGF) from binding to the VEGFR-2[2] In chemistry, a ligand is an atom, ion, or molecule (see also: functional group) that generally donates one or more of its electrons through a coordinate covalent bond to, or shares its electrons through a covalent bond with, one or more central atoms or ions (these ligands act as a... Vascular endothelial growth factor (VEGF) is an important signaling protein involved in both vasculogenesis (the de novo formation of the embryonic circulatory system) and angiogenesis (the growth of blood vessels from pre-existing vasculature). ...


Decoy substrate

A decoy substrate or pseudosubstrate is a protein that has similar structure to the substrate of an enzyme, in order to make the enzyme bind to itself rather than to the real substrate, thus blocking the activity of the enzyme. These proteins are therefore enzyme inhibitors. For other uses, see Substrate. ... Ribbon diagram of the enzyme TIM, surrounded by the space-filling model of the protein. ... HIV protease in a complex with the protease inhibitor ritonavir. ...


Examples include 3KL produced by vaccinia virus, which prevents the immune system of phosphorylating the substrate eIF-2 by having a similar structure to eIF-2. Thus, the vaccinia virus avoids the immune system. Vaccinia is the condition resulting from infection with the Vaccinia virus. ...

Digital decoys

In protein folding simulations, a decoy is a computer-generated protein structure which is designed so to compete with the real structure of the protein. Decoys are used to test the validity of a protein model; the model is considered correct only if is able to identify the native state configuration of the protein among the decoys. Protein before and after folding. ...


Decoys are generally used to overcome a main problem in protein folding simulations: the enormity of the conformational space. For very detailed protein models, it can be practically impossible to explore all the possible configurations to find the native state. To deal with this problem, one can make use of decoys. The idea behind this, is that the native configuration has not to be blindly searched through all possible conformations; the search can be limited to a relevant sub-set of structures. To start with, all non-compact configurations can be excluded. A typical decoy set will include globular conformations of various shapes, some having no secondary structures, some having helices and sheets in different proportions. The computer model being tested will be used to calculate the free energy of the protein in the decoy configurations. The minimum requirement for the model to be correct is that it identifies the native state as the minimum free energy state (see Anfinsen's dogma). Polymer chemistry or macromolecular chemistry is a multidisciplinary science that deals with the chemical synthesis and chemical properties of polymers or macromolecules. ...

The thermodynamic free energy is a measure of the amount of mechanical (or other) work that can be extracted from a system, and is helpful in engineering applications. ...

Decoys as Folk Art

Ever since Joel Barber, the first known decoy collector, started in 1918, decoys have become increasingly viewed as an important form of North American folk art. Barber's book Wild Fowl Decoys, was the first book on decoys as collectible objects. It was followed in 1965 by folk art dealer Adele Earnest's "The Art of the Decoy" and "American Bird Decoys" by collector Wm. F. Mackey. Joel Barber was an early 20th century architect from New York who is best known as an early collector and promoter of duck decoys as folk art. ... Island of Salvation Botanica, Piety Street, Bywater neighborhood, New Orleans Folk art describes a wide range of objects that reflect the craft traditions and traditional social values of various social groups. ... Wild Fowl Decoys is an art reference book by American collector Joel Barber, first published in 1934 by The Derrydale Press. ...


By that time a milestone in collecting had already occurred with the publication of "Decoy Collectors Guide", a small magazine created by hobbyists Hal & Barbara Sorenson of Burlington, Iowa. The 'Guide' helped foster a sense of community and provided a forum for collectors to share their research.


By the 1970s decoys were becoming big business, at least by previous standards. The death of Wm. F. Mackey brought his decoys to market in a series of auctions in 1973 and 1974, with the star of his collection, a Long-billed Curlew by Wm. 'Bill' Bowman selling for a record US$10,500.


Since the 1960s numerous collectors organizations have been created, specialist books and magazines published, with specialist dealers, and special interest shows around the US and Canada.


The largest collectors organization is the Midwest Decoy Collectors Association (MDCA)which despite its name is the de facto international group. MDCA is a non-profit, [[[edit]] 501(c)(3)]] organization which sponsors the biggest show of the year. There are numerous state and regional groups as well.

A new record was set when two decoys (Canadian goose and a preening pintail drake) by A. Elmer Crowell of East Harwich, MA were perportadly sold for $1.13 million dollars each in September, 2007 although this is unclear as they were part of a sale of over 30 decoys for $3.7 million. [4]
