Chromosome 19
Chromosome 19 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 19 spans more than 58.6 million base pairs, the building material of DNA. It is considered the most gene-rich chromosome containing roughly 1,500 genes, despite accounting for only 2 percent of the human genome. Genes Number of genes The following are some of the gene count estimates of human chromosome 19. Because researchers use different approaches to genome annotation, their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project ( CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes. Gene list The following is a partial list of genes on human chromosome 19. For complete list, see the link in the infobox on the ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G Banding
G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. It is useful for identifying genetic diseases through the photographic representation of the entire chromosome complement.Speicher, Michael R. and Nigel P. Carter. "The New Cytogenetics: Blurring the Boundaries with Molecular Biology." ''Nature'' Reviews Genetics, Vol 6. Oct 2005. The metaphase chromosomes are treated with trypsin (to partially digest the chromosome) and stained with Giemsa stain. Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding. In contrast, less condensed chromatin ( Euchromatin)—which tends to be rich with guanine and cytosine ( GC-rich) and more transcriptionally active—incorporates less Giemsa stain, and these regions appear as light bands in G-banding. The pattern of ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensembl Genome Database Project
Ensembl genome database project is a scientific project at the European Bioinformatics Institute, which provides a centralized resource for geneticists, molecular biologists and other researchers studying the genomes of our own species and other vertebrates and model organisms. Ensembl is one of several well known genome browsers for the retrieval of genomic information. Similar databases and browsers are found at NCBI and the University of California, Santa Cruz (UCSC). History The human genome consists of three billion base pairs, which code for approximately 20,000–25,000 genes. However the genome alone is of little use, unless the locations and relationships of individual genes can be identified. One option is manual annotation, whereby a team of scientists tries to locate genes using experimental data from scientific journals and public databases. However this is a slow, painstaking task. The alternative, known as automated annotation, is to use the power of compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATPase ASNA1
ATPase ASNA1 also known as arsenical pump-driving ATPase and arsenite-stimulated ATPase is an enzyme that in humans is encoded by the ASNA1 gene. Function ASNA1 is the human homolog of the bacterial arsA gene. In '' E. coli'', arsA ATPase is the catalytic component of a multisubunit oxyanion pump that is responsible for resistance to arsenicals and antimonials. Interactions ASNA1 is found to interact with FAM71D FAM71D, also known as chromosome 14 open reading frame 54 (C14orf54), is a protein that in humans is encoded by the FAM71D gene on Chromosome 14.

ATG4D
The human ATG4D gene encodes the protein Autophagy related 4D, cysteine peptidase. Function Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non- apoptotic cell death, and aging. Reduced levels of autophagy have been described in some malignant tumors, and a role for autophagy in controlling the unregulated cell growth linked to cancer has been proposed. This gene belongs to the autophagy-related protein 4 (Atg4) family of C54 endopeptidases. Members of this family encode proteins that play a role in the biogenesis of autophagosomes, which sequester the cytosol and organelles for degradation by lysosome A lysosome () is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules. A lysosome h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARMC6
The human gene ARMC6 encodes a protein called Armadillo repeat-containing protein 6. The function of this gene's protein product has not been determined. A related protein in mouse suggests that this protein has a conserved function. The protein is characterized by the presence of armadillo repeats in its amino acid sequence. Diseases associated with ARMC6 include pancreatic cancer, and pancreatitis Pancreatitis is a condition characterized by inflammation of the pancreas. The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. There are two main types: acute pancreatitis, and chronic p ....

ANKRD24
Ankyrin repeat domain-containing protein 24 is a protein in humans that is coded for by the ''ANKRD24'' gene. The gene is also known as ''KIAA1981'.'' The protein's function in humans is currently unknown. ANKRD24 is in the protein family that contains ankyrin-repeat domains. Gene Locus The gene is located on chromosome 19 at p13.3 on the forward strand. The gene is 4041 base pairs in length and contains 29 exons. The gene is neighbored by the gene '' SIRT6'' that encodes for the Sirtuin-6 protein and the ''EBI3'' gene that encodes for the Epstein-Barr virus induced gene 3 protein. Expression The expression pattern of ANKRD24 is uncharacterized. Under conditions of cell growth and proliferation, the expression levels increase. In germ line tumors, glioma, and prostate cancer, the expression is elevated relative to other disease states. During development, the expression level is elevated in the blastocyst stage. In adults, there are elevated levels of expression in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid ...
