SR Protein
SR proteins are a conserved family of proteins involved in RNA splicing. SR proteins are named because they contain a protein domain with long repeats of serine and arginine amino acid residue (chemistry), residues, whose Amino acid#Table of standard amino acid abbreviations and properties, standard abbreviations are "S" and "R" respectively. SR proteins are ~200-600 amino acids in length and composed of two domains, the RNA recognition motif (RRM) region and the RS domain. SR proteins are more commonly found in the nucleus than the cytoplasm, but several SR proteins are known to shuttle between the nucleus and the cytoplasm. SR proteins were discovered in the 1990s in Northern Ireland, Belfast in amphibian oocytes, and later in humans. In general, metazoans appear to have SR proteins and unicellular organisms lack SR proteins. SR proteins are important in constitutive and alternative pre-mRNA splicing, mRNA export, genome stabilization, nonsense-mediated decay, and translation. ...

Socialist Revolutionary Party
The Socialist Revolutionary Party (SR; ,, ) was a major socialist political party in the late Russian Empire, during both phases of the Russian Revolution, and in early Russian Soviet Federative Socialist Republic, Soviet Russia. The party members were known as Esers (). The SRs were Agrarian socialism, agrarian socialists and supporters of a Democratic socialism, democratic socialist Russian republic. The ideological heirs of the Narodniks, the SRs won a mass following among the Russian peasantry by endorsing the overthrow of the Russian Empire, Tsar and the Land reform, redistribution of land to the peasants. The SRs boycotted the 1906 Russian legislative election, elections to the First State Duma (Russian Empire), Duma following the 1905 Russian Revolution, Revolution of 1905 alongside the Russian Social Democratic Labour Party, but chose to run in the elections to the Second Duma and received the majority of the few seats allotted to the peasantry. Following the Coup of Jun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SR Flip-flop Circuit
In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will output its state (often along with its logical complement too). It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems. Flip-flops and latches are used as data storage elements to store a single '' bit'' (binary digit) of data; one of its two states represents a "one" and the other represents a "zero". Such data storage can be used for storage of ''state'', and such a circuit is described as sequential logic in electronics. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs). It can also ...

Southern Railway (UK)
The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the Railways Act 1921, 1923 Grouping. It linked London with the English Channel, Channel ports, South West England, Seaside resort#British seaside resorts, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26–28 The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway. The railway was noted for its astute use of public relations and a coherent management structure headed by Herbert Ashcombe Walker, Sir Herbert Walker. At , the Southern Railway was the smallest of the Big Four (British railway comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nissan SR Engine

Saarländischer Rundfunk
(; "Saarland Broadcasting"), shortened to SR (), is a public broadcasting, public radio and television broadcaster serving the German States of Germany, state of Saarland. With headquarters in the Halberg Broadcasting House in Saarbrücken, SR is a member of the ARD (broadcaster), ARD consortium of German public-broadcasting organizations. History The history of Saarland Radio is closely linked to the history of Saarland, as an independent island between Germany and France. Broadcasting in the Saarland began in 1929, under the League of Nations mandate. In 1935, when the Saar rejoined Germany, Joseph Goebbels's Propagandaministerium established the ''Reichssender Saarbrücken'', under the control of the ''Reichs-Rundfunk-Gesellschaft, Reichs-Rundfunk GmbH Berlin''. The interval signal of Reichssenders Saarbrücken were the first four notes of so called Steigerlied ("Glück auf, Glück auf"). After World War II, the Saarland was placed under French administration as the Saar ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SR Corporation
SR Corporation (, formerly ''Suseo High Speed Rail Corporation''), also known as Supreme Railways, is a South Korean rail operator that operates high-speed rail services. The company was established in December 2013 and adopted its current name in June 2014. In December 2016, SR Corporation officially launched its '' SRT'' (Super Rapid Train) services on an open-access basis. By January 2021, the company's services called at 17 stations, three of which it managed directly. The merger of SR Corporation and the national passenger operator Korail has been repeatedly mooted and fallen through; presently the company remains an independent competitor to the incumbent's KTX services. Recent initiatives have included the greater use of local component production and the in-housing of rolling stock maintenance.

Sarcoplasmic Reticulum
The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+). Calcium ion levels are kept relatively constant, with the concentration of calcium ions within a cell being 10,000 times smaller than the concentration of calcium ions outside the cell. This means that small increases in calcium ions within the cell are easily detected and can bring about important cellular changes (the calcium is said to be a second messenger). Calcium is used to make calcium carbonate (found in chalk) and calcium phosphate, two compounds that the body uses to make teeth and bones. This means that too much calcium within the cells can lead to hardening (calcification) of certain intracellular structures, including the mitochondria, leading to cell death. Therefore, it is vital that calcium ion levels are controlled tightly, and can be released int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
