Structural Genomics Consortium
The Structural Genomics Consortium (SGC) is a public-private-partnership focusing on elucidating the functions and disease relevance of all proteins encoded by the human genome, with an emphasis on those that are relatively understudied. The SGC places all its research output into the public domain without restriction and does not file for patents and continues to promote open science. Two recent publications revisit the case for open science. Founded in 2003, and modelled after the Single Nucleotide Polymorphism Database (dbSNP) Consortium, the SGC is a charitable company whose Members comprise organizations that contribute over $5,4M Euros to the SGC over a five-year period. The Board has one representative from each Member and an independent Chair, who serves one 5-year term. The current Chair is Anke Müller-Fahrnow (Germany), and previous Chairs have been Michael Morgan (U.K.), Wayne Hendrickson (U.S.A.), Markus Gruetter (Switzerland) and Tetsuyuki Maruyama (Japan).

Plasmid
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance. While chromosomes are large and contain all the essential genetic information for living under normal conditions, plasmids are usually very small and contain only additional genes that may be useful in certain situations or conditions. Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. In the laboratory, plasmids may be introduced into a cell via transformation. Synthetic plasmids are available for procurement over the inter ...

Zinc Finger Nuclease
Zinc-finger nucleases (ZFNs) are artificial restriction enzymes generated by fusing a zinc finger DNA-binding domain to a DNA-cleavage domain. Zinc finger domains can be engineered to target specific desired DNA sequences and this enables zinc-finger nucleases to target unique sequences within complex genomes. By taking advantage of endogenous DNA repair machinery, these reagents can be used to precisely alter the genomes of higher organisms. Alongside CRISPR/Cas9 and TALEN, ZFN is a prominent tool in the field of genome editing. Domains DNA-binding domain The DNA-binding domains of individual ZFNs typically contain between three and six individual zinc finger repeats and can each recognize between 9 and 18 basepairs. If the zinc finger domains perfectly recognize a 3 basepair DNA sequence, they can generate a 3-finger array that can recognize a 9 basepair target site. Other procedures can utilize either 1-finger or 2-finger modules to generate zinc-finger arrays with six ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Krüppel-like Factors
In molecular genetics, the Krüppel-like family of transcription factors (KLFs) are a set of eukaryotic C2H2 zinc finger DNA-binding proteins that regulate gene expression. This family has been expanded to also include the Sp transcription factor and related proteins, forming the Sp/KLF family. Members The following human genes encode Kruppel-like factors: KLF1, KLF2, KLF3, KLF4, KLF5, KLF6, KLF7, KLF8, KLF9, KLF10, KLF11, KLF12, KLF13, KLF14, KLF15, KLF16, KLF17 The following genes are Sp factors: Sp1, Sp2, Sp3, Sp4, Sp5, Sp6, Sp7, Sp8, and Sp9. Note that although KLF14 was an alias for Sp6 (), it now refers to a protein () derived from KLF16 by a retrotransposon event. Function and properties KLF/Sps are a family of transcription factors that contain three carboxyl-terminal ( C-terminal) C2H2-type zinc finger structural motifs that bind to the GC-rich regions in DNA and regulate various cellular functions, such as proliferation, diff ...

The Michael J
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

John Gurdon
Sir John Bertrand Gurdon (born 2 October 1933) is a British developmental biologist. He is best known for his pioneering research in nuclear transplantation and cloning. He was awarded the Lasker Award in 2009. In 2012, he and Shinya Yamanaka were awarded the Nobel Prize for Physiology or Medicine for the discovery that mature cells can be converted to stem cells. Early days Gurdon attended Edgeborough and then Eton College, where he ranked last out of the 250 boys in his year group at biology, and was in the bottom set in every other science subject. A schoolmaster wrote a report stating, "I believe he has ideas about becoming a scientist; on his present showing this is quite ridiculous." Gurdon explains it is the only document he ever framed; Gurdon also told a reporter, "When you have problems like an experiment doesn't work, which often happens, it's nice to remind yourself that perhaps after all you are not so good at this job and the schoolmaster may have been right."

Non-profit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworthiness, honesty, and openness to eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mario Capecchi
Mario Ramberg Capecchi (born 6 October 1937) is an Italian-born molecular geneticist and a co-awardee of the 2007 Nobel Prize in Physiology or Medicine for discovering a method to create mice in which a specific gene is turned off, known as knockout mice. He shared the prize with Martin Evans and Oliver Smithies. He is currently Distinguished Professor of Human Genetics and Biology at the University of Utah School of Medicine. Life Mario Capecchi was born in Verona, Italy, as the only child of Luciano Capecchi and Lucy Ramberg, an Italian-born daughter of American-born Impressionist painter Lucy Dodd Ramberg and German archaeologist Walter Ramberg. His parents weren't married, and due to the chaos in Europe caused by World War II, the story of his early life is remarkable, but the details are unclear. In 1941 he and his mother were living near Bolzano, about 160 miles north of his father in Reggio Emilia when his mother was arrested and deported for pamphleteering and belonging ...

Gel Electrophoresis
Gel electrophoresis is a method for separation and analysis of biomacromolecules ( DNA, RNA, proteins, etc.) and their fragments, based on their size and charge. It is used in clinical chemistry to separate proteins by charge or size (IEF agarose, essentially size independent) and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge. Nucleic acid molecules are separated by applying an electric field to move the negatively charged molecules through a matrix of agarose or other substances. Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. Proteins are separated by the charge in agarose because the pores of the gel are too small to sieve proteins. Gel electrophoresis can also be used for the separation of nanoparticles. ...
