POLR2G
DNA-directed RNA polymerase II subunit RPB7 is an enzyme that in humans is encoded by the ''POLR2G'' gene. This gene encodes the seventh largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. In yeast, the association of this subunit with the polymerase under suboptimal growth conditions indicates it may play a role in regulating polymerase function. Interactions POLR2G has been shown to interact with TAF15, POLR2C, POLR2H and POLR2E DNA-directed RNA polymerases I, II, and III subunit RPABC1 is a protein that in humans is encoded by the ''POLR2E'' gene. This gene encodes the fifth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA ....

TAF15
TATA-binding protein-associated factor 2N is a protein that in humans is encoded by the ''TAF15'' gene. Function Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes a subunit of TFIID present in a subset of TFIID complexes. Translocations involving chromosome 17 and chromosome 9, where the g ...

POLR2C
DNA-directed RNA polymerase II subunit RPB3 is an enzyme that in humans is encoded by the ''POLR2C'' gene. Function This gene encodes the third largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene contains a cysteine rich region and exists as a heterodimer with another polymerase subunit, POLR2J. These two subunits form a core subassembly unit of the polymerase. A pseudogene has been identified on chromosome 21. Interactions POLR2C has been shown to interact with: * ATF4, * CCHCR1, * Myogenin, * POLR2A, * POLR2B, * POLR2E and * POLR2F, * POLR2G, * POLR2H, * POLR2J, * POLR2K, * POLR2L, and * TAF15 TATA-binding protein-associated factor 2N is a protein that in humans is encoded by the ''TAF15'' gene.

POLR2H
DNA-directed RNA polymerases I, II, and III subunit RPABC3 is a protein that in humans is encoded by the ''POLR2H'' gene. This gene encodes one of the essential subunits of RNA polymerase II that is shared by the other two eukaryotic DNA-directed RNA polymerases, I and III. Interactions POLR2H has been shown to interact with POLR2C, POLR2G, POLR2A, POLR2B and POLR2E DNA-directed RNA polymerases I, II, and III subunit RPABC1 is a protein that in humans is encoded by the ''POLR2E'' gene.

Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
