Until the 1950s, not been made that an attempt to seek a linker molecule specific to the cell membrane. The Waser, using radiolabeled curare – can block the neurotransmitter released from motor nerve receptors of acetylcholine, in skeletal muscle is known – material is connected to the muscles of the neuromuscular junction revealed by (photo detection of radioactivity) autoradiography, that, the nerve fibers where muscle is associated with exactly.
Humphrey call radioactive atropine and pharmacologist William Payton of semen Research UK’s another, used to bind to smooth muscle membrane known prevent the effect of acetylcholine in the parasympathetic endings atropine. Specific binding molecule, therefore, for the first time, they will be able number of acetylcholine receptors are located in the smooth muscle (known herein as muscarinic type) to determine the final size.
Substance “messenger” to join, it is not a mediator of all released from the nerve endings to the receptor on the cell membrane that exists in nature. Secreted by the endocrine glands, some of these hormones, which circulate in the blood and through the capillary wall to gain access to tissue fluid around their target cells. Others are released by cells that act on other cells in the neighborhood, such as autocoid and “local hormone”.
In general, each receptor is the product of a single gene. Until now, many genes have been cloned the receptor, to know about the mechanisms and molecular structure of the receptor many. DNA binding sites, can be classified according to their biological functions. Therefore, it is possible to distinguish transcription factor binding site of one recombination site and restriction sites. Some authors have suggested that it is possible binding sites are classified according to the most convenient way of expression. Meanwhile, it is possible to introduce the restriction site consensus sequence. They are identical sequences, mainly because it rapidly decreases in an array of similar restriction performance is small. On the other hand, the degree of affinity for transcription factor binding sites in various different, usually, DNA binding sites of transcription factors, is very different. This is to reflect the transcription factor binding site consensus sequences in difficult precisely, usually, they are represented using frequency location particular matrix that is plotted using a logo of a sequence often (PSFM). However, this argument is an optional part. Thus, keen affinity for transcription factors and restriction enzymes, and the different sites, said to be round, I is represented by the best PSFM yield, and also gradually. Similarly, the site-specific recombinase, indicating a diverse range of different affinities to target sites.
The existence of such a thing as a DNA-binding site, is suspected of experimental biological regulation of the lac operon of Escherichia coli and bacteriophage lambda. Finally, the advent of recombinant DNA technology, DNA-binding sites have been identified in the two systems. From that moment, many transcription factors, DNA binding site for the restriction enzyme site-specific recombinase has been found using the abundance of the experimental procedure. Historically speaking, DN DNase footprint analysis, electrophoretic mobility shift experiment Composition method of choice for detecting the DNA binding site, is analyzed were (EMSA). However, the development of fast sequencing techniques and DNA microarray, has led to a new parallel, substantially in vivo methods for identifying binding sites of the chip arrays and chips tip. It is used for quantification of binding affinity of other molecules to the DNA binding site specific for protein and micro-scale thermophoresis law biophysical.

In bioinformatics, the two separate with a DNA-binding site: Search of additional members of the (sequence discovery of new DNA-binding motif in the collection of related sequences in function to the (problem in the site search) DNA binding motif known motif discovery problem that can be distinguished from the problem). Have been proposed for many different ways to search for binding sites. Other authors rely on the method of artificial neural networks and machine learning, but most of them are dependent on the Web server is available with the principles of information theory (Yellaboina) to (Munch). I can be used for algorithm opening sequence motif of many. The set of sequences, these methods rely on the hypothesis that share a binding motif for functional reasons. The discovery method of binding motif, can be divided into number roughly, and consensus stochastic.MEME and determinism of sampling Gibbs conditions application of stochastic methods purely for the discovery of DNA-binding motif and deterministic optimization It is a typical example.葯容 vessel of this class has a method SeSiMCMC that focus on vulnerability TFBS symmetric. In many cases, on the other hand rely on representation of regular expression of the binding site, the method of numerical calculation is a representation of choice for probabilistic method and determinism information theory of a method of treatment of perfunctory and PSFM. Also, the hybrid method as squirrel, such as a combination of greedy and optimization using sampling PSFM,,. As exemplified by the sophisticated method for the discovery and PhyloGibbs.More binding site motif search, progress of the sequence that led to the introduction of comparative genomic approach to find the DNA binding motif, other DNA base between the base stacking it is dependent on the interaction, but the sample size is small are available for binding sites on the DNA due to the effect are not fully utilized. Examples of such tools, it is ULPB.
