RNA-binding Protein EWS
RNA-binding protein EWS is a protein that in humans is encoded by the ''EWSR1'' gene on human chromosome 22, specifically 22q12.2. It is one of 3 proteins in the FET protein family. The q22.2 region of chromosome 22 encodes the N-terminal transactivation domain of the EWS protein and that region may become joined to one of several other chromosomes which encode various transcription factors, see and the FET protein family. The expression of a chimeric protein with the EWS transactivation domain fused to the DNA binding region of a transcription factor generates a powerful oncogenic protein causing Ewing sarcoma and other members of the Ewing family of tumors. These translocations can occur due to chromoplexy, a burst of complex chromosomal rearrangements seen in cancer cells. The normal EWS gene encodes an RNA binding protein closely related to FUS (gene) and TAF15, all of which have been associated to amyotrophic lateral sclerosis. Interactions The EWS protein has been shown to ... [...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 residue ...

ATF1
Cyclic AMP-dependent transcription factor ATF-1 is a protein that in humans is encoded by the ''ATF1'' gene. This gene encodes an activating transcription factor, which belongs to the ATF subfamily and bZIP (basic-region leucine zipper) family. It influences cellular physiologic processes by regulating the expression of downstream target genes, which are related to growth, survival, and other cellular activities. This protein is phosphorylated at serine 63 in its kinase-inducible domain by serine/threonine kinases, cAMP-dependent protein kinase A, calmodulin-dependent protein kinase I/II, mitogen- and stress-activated protein kinase and cyclin-dependent kinase 3 (cdk-3). Its phosphorylation enhances its transactivation and transcriptional activities, and enhances cell transformation. Clinical significance Fusion of this gene and FUS on chromosome 16 or EWSR1 on chromosome 22 induced by translocation generates chimeric proteins in angiomatoid fibrous histiocytoma and clear c ...

SF1 (gene)
Splicing factor 1 also known as zinc finger protein 162 (ZFM162) is a protein that in humans is encoded by the ''SF1'' gene. Splicing factor SF1 is involved in the ATP-dependent formation of the spliceosome complex. SF1 gene is necessary to make the bipotential gonad ; but while SF1 levels decline in the genital ridge of XX mouse embryos, the SF1 gene stays on the developing testes. SF 1 (transcription factor) appears to be active in masculining both the Leydig cells and Sertoli cells. In Sertoli cells with the SOX9 protein it elevates the level of AMH transcription. In Leydig cells it activates the gene encoding the enzyme that make testosterone hormone.

PTK2B
Protein tyrosine kinase 2 beta is an enzyme that in humans is encoded by the ''PTK2B'' gene. Function This gene encodes a cytoplasmic protein tyrosine kinase that is involved in calcium-induced regulation of ion channels and activation of the map kinase signaling pathway. The encoded protein may represent an important signaling intermediate between neuropeptide-activated receptors or neurotransmitters that increase calcium flux and the downstream signals that regulate neuronal activity. The encoded protein undergoes rapid tyrosine phosphorylation and activation in response to increases in the intracellular calcium concentration , nicotinic acetylcholine receptor activation, membrane depolarization, or protein kinase C activation. In addition, SOCE-induced Pyk2 activation mediates disassembly of endothelial adherens junctions, via tyrosine (Y1981-residue) phosphorylation of VE-PTP. This protein has been shown to bind a CRK-associated substrate, a nephrocystin, a GTPase reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POU4F1
POU domain, class 4, transcription factor 1 (POU4F1) also known as brain-specific homeobox/POU domain protein 3A (BRN3A), homeobox/POU domain protein RDC-1 or Oct-T1 is a protein that in humans is encoded by the ''POU4F1'' gene. BRN3A (POU4F1) is a class IV POU domain-containing transcription factor highly expressed in the developing peripheral sensory nervous system (dorsal root ganglia, trigeminal ganglion, and hindbrain sensory ganglia), certain regions of the central nervous system, retinal neurons called ganglion cells, and in cells of the B- and T-lymphocytic lineages. Discovery Brn3a was initially discovered in mice based on homology to the prototypal POU transcription factors Pit1 (Pituitary-specific positive transcription factor 1, Pou1f1), Oct1 (Pou2f1), and the Caenorhabditis elegans factor Unc86, and named Brn3. When multiple members of the Brn3 gene class were discovered, it was renamed Brn3.0 and Brn3a by different groups of researchers. Subsequently, the gene was ...

ERG (gene)
''ERG'' (''ETS-related gene'') is an oncogene. ERG is a member of the ETS transcription factor family, ETS (erythroblast transformation-specific) family of transcription factors. The ''ERG'' gene encodes for a protein, also called ERG, that functions as a transcriptional regulator. Genes in the ETS family regulate embryonic development, cell proliferation, differentiation (cellular), differentiation, angiogenesis, inflammation, and apoptosis. Function Transcriptional regulator ERG is a nuclear protein that binds purine-rich sequences of DNA. Transcriptional regulator ERG is required for platelet adhesiveness, platelet adhesion to the Endothelium, subendothelium and regulates hematopoiesis. It has a DNA binding domain and a PNT (pointed) domain. ERG is expressed at higher levels in early myelocytes than in mature lymphocytes (types of white blood cells). Therefore, ERG may act as a regulator of differentiation of early hematopoietic cells. The Mld2 mutation, generated through an ...

BARD1
BRCA1-associated RING domain protein 1 is a protein that in humans is encoded by the ''BARD1'' gene. The human BARD1 protein is 777 amino acids long and contains a RING finger domain (residues 46-90), four ankyrin repeats (residues 420-555), and two tandem BRCT domains (residues 568-777). Function Most, if not all, BRCA1 heterodimerizes with BARD1 in vivo. BARD1 and BRCA1 form a heterodimer via their N-terminal RING finger domains. The BARD1-BRCA1 interaction is observed in vivo and in vitro and is essential for BRCA1 stability. BARD1 shares homology with the two most conserved regions of BRCA1: the N-terminal RING motif and the C-terminal BRCT domain. The RING motif is a cysteine-rich sequence found in a variety of proteins that regulate cell growth, including the products of tumor suppressor genes and dominant protooncogenes, and developmentally important genes such as the polycomb group of genes. The BARD1 protein also contains three tandem ankyrin repeats. The BARD1/BRCA1 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig's disease, is a neurodegenerative disease that results in the progressive loss of motor neurons that control voluntary muscles. ALS is the most common type of motor neuron diseases. Early symptoms of ALS include stiff muscles, muscle twitches, and gradual increasing weakness and muscle wasting. ''Limb-onset ALS'' begins with weakness in the arms or legs, while ''bulbar-onset ALS'' begins with difficulty speaking or swallowing. Half of the people with ALS develop at least mild difficulties with thinking and behavior, and about 15% develop frontotemporal dementia. Most people experience pain. The affected muscles are responsible for chewing food, speaking, and walking. Motor neuron loss continues until the ability to eat, speak, move, and finally the ability to breathe is lost. ALS eventually causes paralysis and early death, usually from respiratory failure. Most cases of ALS (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
