Chromosome 7
Chromosome 7 is one of the 23 pairs of chromosomes in humans, who normally have two copies of this chromosome. Chromosome 7 spans about 160 million base pairs (the building material of DNA) and represents between 5 and 5.5 percent of the total DNA in cells. Genes Number of genes The following are some of the gene count estimates of human chromosome 7. 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 7. For complete list, see the link in the infobox on the right. Diseases and disorders The following diseases are some of those related to gene ...

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 (mainly chromosomal abnormalities) 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. Method The metaphase chromosomes are treated with trypsin (to partially digest the chromosome) and Staining (biology), stained with Giemsa stain. Heterochromatin, 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-content, GC-rich) and more Transcription (genetics), transcriptionally acti ...

BRAT1
BRCA1-associated ATM activator 1 is a protein in humans that is encoded by the BRAT1 gene. Function The protein encoded by this ubiquitously expressed gene interacts with the tumor suppressing BRCA1 (breast cancer 1) protein and the ATM (ataxia telangiectasia mutated) protein. ATM is thought to be a master controller of cell cycle checkpoint signalling pathways that are required for cellular responses to DNA damage such as double-strand break DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. A weakened capacity for DNA repair is a risk factor for the development of cancer. DNA is constantly modified ...s that are induced by ionizing radiation and complexes with BRCA1 in the multi-protein complex BASC (BRCA1-associated genome surveillance complex). The protein encoded by this gene is thought to play a role in the DNA damage pathway regulated by BRCA1 and ATM. References External links ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 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 pep ...

AGK (gene)
The human gene AGK encodes the enzyme mitochondrial acylglycerol kinase. The protein encoded by this gene is a mitochondrial membrane protein involved in lipid and glycerolipid metabolism. It catalyzes the formation of phosphatidic and lysophosphatidic acids. Defects in this gene have been associated with mitochondrial DNA depletion syndrome 10. Diseases associated with AGK include cataracts and cardiomyopathy. An important paralog of this gene is CERKL. Structure The AGK gene is located on the 7th chromosome, with its specific location being 7q34. The gene contains 18 exons. AGK encodes a 47.1 kDa protein that is composed of 422 amino acids; 32 peptides have been observed through mass spectrometry data.] Function Acylglycerol kinase synthesizes phosphatidic and lysophosphatidic acids. The enzyme uses ATP to put a phosphate group on acyl glycerol and diacylglycerol. It catalyzes the following reactions: ATP + acylglycerol = ADP + acyl-sn-glycerol 3-phosphate. ATP + 1,2-diac ...

Alpha-aminoadipic Semialdehyde Synthase, Mitochondrial
Alpha-aminoadipic semialdehyde synthase is an enzyme encoded by the AASS gene in humans and is involved in their major lysine degradation pathway. It is similar to the separate enzymes coded for by the LYS1 and LYS9 genes in yeast, and related to, although not similar in structure, the bifunctional enzyme found in plants. In humans, mutations in the AASS gene, and the corresponding alpha-aminoadipic semialdehyde synthase enzyme are associated with familial hyperlysinemia. This rare disease is inherited in an autosomal recessive pattern and patients often have no clinical symptoms. Function The alpha-aminoadipic semialdehyde synthase protein catalyzes the first two steps in the mammalian L-lysine degradation via saccharopine pathway within the mitochondria, which is thought to be the main metabolic route for lysine degradation in upper eukaryotes. The specific subpathway that this enzyme focuses on is the synthesis of glutaryl-CoA from L-lysine. Glutaryl-CoA can act as an ...
