| 产品编号 | bs-16569P |
| 英文名称 | GNAT1 Antibody Blocking Peptide |
| 中文名称 | GBT1蛋白封闭多肽 |
| 英文别名 | CSNBAD3; GBT1; GNAT1; GNATR; GNAT1_HUMAN; guanine nucleotide binding protein (G protein) alpha transducing activity polypeptide 1; guanine nucleotide binding protein G(T) alpha 1 subunit; guanine nucleotide-binding protein G(t) subunit alpha-1; Rod specific transducin; rod-type transducin alpha subunit; transducin alpha-1 chain; transducin, rod-specific. |

| 亚基 | G proteins are composed of 3 units; alpha, beta and gamma. The alpha chain contains the guanine nucleotide binding site. Interacts (when myristoylated) with UNC119; interaction is required for localization in sensory neurons. |
| 组织特异性 | Rod. |
| 相似性 | Belongs to the G-alpha family. G(i/o/t/z) subfamily. |
| 功能 | Vision involves the conversion of light into electrochemical signals that are processed by the retina and subsequently sent to and interpreted by the brain. The process of converting light into an electrochemical signal begins when the membrane-bound protein, rhodopsin, absorbs light within the retina. Photoexcitation of rhodopsin causes the cytoplasmic surface of the protein to become catalytically active. In the active state, rhodopsin activates transducin, a GTP binding protein. Once activated, transducin promotes the hydrolysis of cGMP by phosphodiesterase (PDE). The decrease of intracellular cGMP concentration causes the ion channels within the outer segment of the rod or cone to close, thus causing membrane hyperpolarization and, eventually, signal transmission. Rhodopsin activity is believed to be shut off by phosphorylation followed by binding of the soluble protein, arrestin. Transducin, once activated by rhodopsin, promotes the hydrolysis of cGMP by PDE. The subunit composition of transducin differs between different photoreceptor cells. Rod transducin consists of rod transducin alpha (Tr alpha), T beta, and T gamma. Cone transducin is composed of cone transducin alpha (Tc alpha), T beta and T gamma. Differential transducin subunit composition of transducin is believed to be responsible for the different light sensitivities between photoreceptive cells. |

| 背景资料 | Transducin is a 3-subunit guanine nucleotide-binding protein (G protein) which stimulates the coupling of rhodopsin and cGMP-phoshodiesterase during visual impulses. The transducin alpha subunits in rods and cones are encoded by separate genes. This gene encodes the alpha subunit in rods. This gene is also expressed in other cells, and has been implicated in bitter taste transduction in rat taste cells. Mutations in this gene result in autosomal dominant congenital stationary night blindness. Multiple alternatively spliced variants, encoding the same protein, have been identified.
