Notch 1
Neurogenic locus notch homolog protein 1 (Notch 1) is a protein encoded in humans by the ''NOTCH1'' gene. Notch 1 is a single-pass transmembrane receptor. Function This gene encodes a member of the Notch family. Members of this Type 1 transmembrane protein family share structural characteristics including an extracellular domain consisting of multiple epidermal growth factor-like (EGF) repeats, and an intracellular domain consisting of multiple, different domain types. Notch family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling network is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells. In ''Drosophila'', notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signaling pathway that plays a key role in development. Homologues of the notch-ligands have also been identified in humans, but precise interac ... [...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] |
Astrocyte
Astrocytes (from Ancient Greek , , "star" + , , "cavity", "cell"), also known collectively as astroglia, are characteristic star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical control of endothelial cells that form the blood–brain barrier, provision of nutrients to the nervous tissue, maintenance of extracellular ion balance, regulation of cerebral blood flow, and a role in the repair and scarring process of the brain and spinal cord following infection and traumatic injuries. The proportion of astrocytes in the brain is not well defined; depending on the counting technique used, studies have found that the astrocyte proportion varies by region and ranges from 20% to 40% of all glia. Another study reports that astrocytes are the most numerous cell type in the brain. Astrocytes are the major source of cholesterol in the central nervous system. Apolipoprotein E transports cholesterol from astrocytes to neurons and other glial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SNW1
SNW domain-containing protein 1 is a protein that in humans is encoded by the ''SNW1'' gene. Function This gene, a member of the SNW gene family, encodes a coactivator that enhances transcription from some Pol II promoters. This coactivator can bind to the ligand-binding domain of the vitamin D receptor and to retinoid receptors to enhance vitamin D-, retinoic acid-, estrogen-, and glucocorticoid-mediated gene expression. It can also function as a splicing factor by interacting with poly(A)-binding protein 2 to directly control the expression of muscle-specific genes at the transcriptional level. Finally, the protein may be involved in oncogenesis since it interacts with a region of SKI oncoproteins that is required for transforming activity. Interactions SNW1 has been shown to interact with: * CIR, * Calcitriol receptor, * Histone deacetylase 2, * Mothers against decapentaplegic homolog 2, * Mothers against decapentaplegic homolog 3, * NOTCH1 * Nuclear receptor co-rep ...

NOV (gene)
NOV (nephroblastoma overexpressed) also known as CCN3 is a matricellular protein that in humans is encoded by the ''NOV'' gene. CCN family NOV is a member of the CCN family of secreted, extracellular matrix (ECM)-associated signaling proteins (see also CCN intercellular signaling protein). The CCN acronym is derived from the first three members of the family being identified, namely CYR61 (cysteine-rich angiogenic inducer 61, or CCN1), CTGF (connective tissue growth factor, or CCN2), and NOV. These proteins, together with WISP1 (CCN4), WISP2 (CCN5), and WISP3 (CCN6) comprise the six-member CCN family in vertebrates and have been renamed CCN1-6 in the order of their discovery by international consensus. Structure The human NOV protein contains 357 amino acids with an N-terminal secretory signal peptide followed by four structurally distinct domains with homologies to insulin-like growth factor binding protein (insulin-like growth factor-binding protein, IGFBP), von Willebrand ...

NFKB1
Nuclear factor NF-kappa-B p105 subunit is a protein that in humans is encoded by the ''NFKB1'' gene. This gene encodes a 105 kD protein which can undergo cotranslational processing by the 26S proteasome to produce a 50 kD protein. The 105 kD protein is a Rel protein-specific transcription inhibitor and the 50 kD protein is a DNA binding subunit of the NF-kappaB (NF-κB) protein complex. NF-κB is a transcription factor that is activated by various intra- and extra-cellular stimuli such as cytokines, oxidant-free radicals, ultraviolet irradiation, and bacterial or viral products. Activated NF-κB translocates into the nucleus and stimulates the expression of genes involved in a wide variety of biological functions; over 200 known genes are targets of NF-κB in various cell types, under specific conditions. Inappropriate activation of NF-κB has been associated with a number of inflammatory diseases while persistent inhibition of NF-κB leads to inappropriate immune cell development ...

Mothers Against Decapentaplegic Homolog 3
Mothers against decapentaplegic homolog 3 also known as SMAD family member 3 or SMAD3 is a protein that in humans is encoded by the SMAD3 gene. SMAD3 is a member of the SMAD family of proteins. It acts as a mediator of the signals initiated by the transforming growth factor beta (TGF-β) superfamily of cytokines, which regulate cell proliferation, differentiation and death. Based on its essential role in TGF beta signaling pathway, SMAD3 has been related with tumor growth in cancer development. Gene The human SMAD3 gene is located on chromosome 15 on the cytogenic band at 15q22.33. The gene is composed of 9 exons over 129,339 base pairs. It is one of several human homologues of a gene that was originally discovered in the fruit fly ''Drosophila melanogaster''. The expression of SMAD3 has been related to the mitogen-activated protein kinase (MAPK/ERK pathway), particularly to the activity of mitogen-activated protein kinase kinase-1 (MEK1). Studies have demonstrated that inhi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MAML1
Mastermind-like protein 1 is a protein that in humans is encoded by the ''MAML1'' gene. Function This protein is the human homolog of mastermind, a Drosophila protein that plays a role in the Notch signaling pathway involved in cell-fate determination. There is in vitro evidence that the human homolog forms a complex with the intracellular portion of human Notch receptors and can increase expression of a Notch-induced gene. This evidence supports its proposed function as a transcriptional co-activator in the Notch signaling pathway. Details on the activity of the N-terminal domain of Mastermind-like protein 1 may be found under MamL-1. Interactions MAML1 has been shown to interact with EP300 and NOTCH1 Neurogenic locus notch homolog protein 1 (Notch 1) is a protein encoded in humans by the ''NOTCH1'' gene. Notch 1 is a single-pass transmembrane receptor. Function This gene encodes a member of the Notch family. Members of this Type 1 trans .... References Fur ...

GSK3B
Glycogen synthase kinase-3 beta, (GSK-3 beta), is an enzyme that in humans is encoded by the ''GSK3B'' gene. In mice, the enzyme is encoded by the Gsk3b gene. Abnormal regulation and expression of GSK-3 beta is associated with an increased susceptibility towards bipolar disorder. Function Glycogen synthase kinase-3 (GSK-3) is a proline-directed serine-threonine kinase that was initially identified as a phosphorylating and an inactivating agent of glycogen synthase. Two isoforms, alpha (GSK3A) and beta, show a high degree of amino acid homology. GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation. It might be a new therapeutic target for ischemic stroke. Disease relevance Homozygous disruption of the Gsk3b locus in mice results in embryonic lethality during mid-gestation. This lethality phenotype could be rescued by inhibition of tumor necrosis factor. Two SNPs at this gene, rs334558 (-50T/C) and rs3755557 (-1727A/T), are associat ...

Dentate Gyrus
The dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum. The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, the spontaneous exploration of novel environments and other functions. It is notable as being one of a select few brain structures known to have significant rates of adult neurogenesis in many species of mammals, from rodents to primates. Other sites of adult neurogenesis include the subventricular zone, the striatum and the cerebellum. However, whether significant neurogenesis exists in the adult human dentate gyrus has been a matter of debate. 2019 evidence has shown that adult neurogenesis does take place in the subventricular zone and in the subgranular zone of the dentate gyrus. Structure The dentate gyrus, like the hippocampus, consists of three distinct layers: an outer molecular layer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
