A PLC can be either an unlisted or listed company on the stock exchanges. In the United Kingdom, a public limited company usually must include the words "public limited company" or the abbreviation "PLC" or "plc" at the end and as part of the legal company name. Welsh companies may instead choose to end their names with ccc, an abbreviation for cwmni cyfyngedig cyhoeddus. However, some public limited companies (mostly nationalised concerns) incorporated under special legislation are exempted from bearing any of the identifying suffixes.
The term "public limited company" and the "PLC"/"plc" suffix were introduced in 1974; prior to this, all limited companies bore the suffix "Limited" ("Ltd"), which is still used by private limited companies.
Phospholipase C, gamma 1, also known as PLCG1, is a protein that in humans is encoded by the PLCG1gene.
The protein encoded by this gene catalyzes the formation of inositol 1,4,5-trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate. This reaction uses calcium as a cofactor and plays an important role in the intracellular transduction of receptor-mediated tyrosine kinase activators. For example, when activated by SRC, the encoded protein causes the Rasguanine nucleotide exchange factorRASGRP1 to translocate to the Golgi apparatus, where it activates Ras. Also, this protein has been shown to be a major substrate for heparin-binding growth factor 1 (acidic fibroblast growth factor)-activated tyrosine kinase. The receptor protein tyrosine phosphatase PTPmu (PTPRM) is capable of dephosphorylating PLCG1. Two transcript variants encoding different isoforms have been found for this gene.
Has been shown to interact with CISH which negatively regulates it by targeting it for degradation. The deletion of Cish in effector T cells has been shown to augment TCR signaling and subsequent effector cytokine release, proliferation and survival. The adoptive transfer of tumor-specific effector T cells knocked out or knocked down for CISH resulted in a significant increase in functional avidity and long-term tumor immunity. There are no changes in activity or phosphorylation of Cish's purported target, STAT5 in either the presence or absence of Cish.
Phosphoinositide phospholipase C (PLC) (EC18.104.22.168, triphosphoinositide phosphodiesterase, phosphoinositidase C, 1-phosphatidylinositol-4,5-bisphosphate phosphodiesterase, monophosphatidylinositol phosphodiesterase, phosphatidylinositol phospholipase C, PI-PLC, 1-phosphatidyl-D-myo-inositol-4,5-bisphosphate inositoltrisphosphohydrolase) is a family of eukaryotic intracellular enzymes that play an important role in signal transduction processes. These enzymes belong to a larger superfamily of Phospholipase C. Other families of phospholipase C enzymes have been identified in bacteria and trypanosomes. Phospholipases C are phosphodiesterases.
Capital sharp s (ẞ) is the majuscule of eszett. Sharp s is unique among the letters of the Latin alphabet in that it has no traditional upper case form. This is because it never occurs word-initially in German text, and traditional German printing (which used blackletter) never used all-caps. When using all-caps, traditional spelling rules required the replacement of ß with SS. However, in 2010, the use of the capital ẞ became mandatory in official documentation in Germany when writing geographical names in all-caps.
There have been repeated attempts to introduce a majuscule ß. Such letterforms can be found in some old German books dating back to the late 19th century and some later signage and product design. One of the best known examples is the East German 1957 Duden.
Inclusion in Universal Character Set
A proposal by Andreas Stötzner to the Unicode Consortium for the inclusion of capital double s in the Universal Character Set was rejected in 2004, on the basis that capital ß is a typographical issue, and therefore not suitable for character encoding. A reworked version of Stötzner's proposal was submitted on 25 April 2007 by DIN. The proposal suggested the Unicode name LATIN CAPITAL LETTER SHARP S. The proposal has been adopted and the character was added as Unicode character "ẞ" U+1E9E LATIN CAPITAL LETTER SHARP S when Unicode 5.1 was released, on 4 April 2008.
Capital is a type of good that can be consumed now, but if consumption is deferred, an increased supply of consumable goods is likely to be available later. Adam Smith defines capital as "That part of a man's stock which he expects to afford him revenue is called his capital." Capital is derived from the Latin word "caput" meaning head, as in "head of cattle". The term "stock" is derived from the Old English word for stump or tree trunk, i.e. something that grows over time. It has been used to refer to all the moveable property of a farm since at least 1510. In Middle Ages France contracted leases and loans bearing interest specified payment in heads of cattle.
How a capital good is maintained or returned to its pre-production state varies with the type of capital involved. In most cases capital is replaced after a depreciation period as newer forms of capital make continued use of current capital non profitable. It is also possible that advances make an obsolete form of capital practical again.
