ILF3
Interleukin enhancer-binding factor 3 is a protein that in humans is encoded by the ''ILF3'' gene. Function Nuclear factor of activated T-cells (NFAT) is a transcription factor required for T-cell expression of interleukin 2. NFAT binds to a sequence in the IL2 enhancer known as the antigen receptor response element 2. In addition, NFAT can bind RNA and is an essential component for encapsidation and protein priming of hepatitis B viral polymerase. NFAT is a heterodimer of 45 kDa and 90 kDa proteins, the larger of which is the product of this gene. The encoded protein, which is primarily localized to ribosomes, probably regulates transcription at the level of mRNA elongation. At least three transcript variants encoding three different isoforms have been found for this gene. Interactions ILF3 has been shown to interact with: * DNA-PKcs, * FUS, * PRMT1 * Protein kinase R Protein kinase RNA-activated also known as protein kinase R (PKR), interferon-induced, double-strand ...

XPO5
gene ID :57510 Exportin-5 (XPO5) is a protein that, in humans, is encoded by the ''XPO5'' gene. In eukaryotic cells, the primary purpose of XPO5 is to export pre-microRNA (also known as pre-miRNA) out of the nucleus and into the cytoplasm, for further processing by the Dicer enzyme. Once in the cytoplasm, the microRNA (also known as miRNA) can act as a gene silencer by regulating translation of mRNA. Although XPO5 is primarily involved in the transport of pre-miRNA, it has also been reported to transport tRNA. Much research on XPO5 is ongoing. miRNA is a prominent research topic due to its potential use as a therapeutic, with several miRNA-based drugs already in use. Mechanism Binding to pre-miRNA After RanGTP binds to XPO5, the XPO5-RanGTP complex forms a U-like structure to hold the pre-miRNA. The XPO5-RanGTP complex recognizes pre-miRNA by its two-nucleotide 3’ overhang—a sequence consisting of two bases at the 3’ end of the pre-miRNA that are not paired with oth ...

C5orf36
KIAA0825 is a protein that in humans is encoded by the gene of the same name, located on chromosome 5, 5q15. It is a possible risk factor in Type II Diabetes, and associated with high levels of glucose in the blood. It is a relatively fast mutating gene, compared to other coding genes. There is however one region which is highly conserved across the species that have the gene, known as DUF4495. It is predicted to travel between the nucleus and the cytoplasm. General information KIAA0825 is gene that appears to be a genetic factor that increases the risk of Type II Diabetes, possibly by increasing the level of blood glucose levels. It has also been identified as a possible oncogene. C5orf36 has one common alias KIAA0825. The gene is about 478 kb long and contains 22 exons. It produces 10 different variants: 9 alternatively spliced, and one un-spliced version. The longest experimentally confirmed mRNA is 7240 bp long and produces a protein 1275 amino acids long. The protein is pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA-PKcs
DNA-dependent protein kinase, catalytic subunit, also known as DNA-PKcs, is an enzyme that in humans is encoded by the gene designated as ''PRKDC'' or ''XRCC7''. DNA-PKcs belongs to the phosphatidylinositol 3-kinase-related kinase protein family. The DNA-Pkcs protein is a serine/threonine protein kinase comprising a single polypeptide chain of 4,128 amino acids. Function DNA-PKcs is the catalytic subunit of a nuclear DNA-dependent serine/threonine protein kinase called DNA-PK. The second component is the autoimmune antigen Ku. On its own, DNA-PKcs is inactive and relies on Ku to direct it to DNA ends and trigger its kinase activity. DNA-PKcs is required for the non-homologous end joining (NHEJ) pathway of DNA repair, which rejoins double-strand breaks. It is also required for V(D)J recombination, a process that utilizes NHEJ to promote immune system diversity. DNA-PKcs knockout mice have severe combined immunodeficiency due to their V(D)J recombination defect. Many proteins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FUS (gene)
RNA-binding protein FUS/TLS (FUused in Sarcoma/Translocated in LipoSarcoma), also known as heterogeneous nuclear ribonucleoprotein P2 is a protein that in humans is encoded by the ''FUS'' gene. Discovery FUS/TLS was initially identified as a fusion protein (FUS-CHOP) produced as a result of chromosomal translocations in human cancers, especially liposarcomas. In these instances, the promoter and N-terminal part of FUS/TLS is translocated to the C-terminal domain of various DNA-binding transcription factors (e.g. CHOP) conferring a strong transcriptional activation domain onto the fusion proteins. FUS/TLS was independently identified as the hnRNP P2 protein, a subunit of a complex involved in the maturation of pre-mRNA. Structure FUS/TLS is a member of the FET protein family that also includes the EWS protein, the TATA-binding protein TBP-associated factor TAFII68/TAF15, and the Drosophila cabeza/SARF protein. FUS/TLS, EWS and TAF15 have a similar structure, characteris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRMT1
Protein arginine N-methyltransferase 1 is an enzyme that in humans is encoded by the ''PRMT1'' gene. The HRMT1L2 gene encodes a protein arginine methyltransferase that functions as a histone methyltransferase specific for histone H4. Function PRMT1 gene encodes for the protein arginine methyltransferase that functions as a histone methyltransferase specific for histone H4 in eukaryotic cells. Specifically altering histone H4 in eukaryotes gives it the ability to remodel chromatin acting as a post-translational modifier. Through regulation of gene expression, arginine methyltransferases control the cell cycle and death of eukaryotic cells. Reaction pathway While all PRMT enzymes catalyze the methylation of arginine residues in proteins, PRMT1 is unique in that is catalyzes the formation of asymmetric dimethylarginine as opposed to the PRMT2 that catalyzes the formation of symmetrically dimethylated arginine. Individual PRMT utilize ''S''-adenosyl-L-methionine (SAM) as the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein Kinase R
Protein kinase RNA-activated also known as protein kinase R (PKR), interferon-induced, double-stranded RNA-activated protein kinase, or eukaryotic translation initiation factor 2-alpha kinase 2 (EIF2AK2) is an enzyme that in humans is encoded by the ''EIF2AK2'' gene. PKR protects against viral infections. Mechanism of action Protein kinase-R is activated by double-stranded RNA (dsRNA), introduced to the cells by a viral infection. PKR can also be activated by the protein PACT or by heparin. PKR contains an N-terminal dsRNA binding domain (dsRBD) and a C-terminal kinase domain, that gives it pro-apoptotic (cell-killing) functions. The dsRBD consists of two tandem copies of a conserved double stranded RNA binding motif, dsRBM1 and dsRBM2. PKR is induced by interferon in a latent state. Binding to dsRNA is believed to activate PKR by inducing dimerization and subsequent auto-phosphorylation reactions. In situations of viral infection, the dsRNA created by viral replication and g ...

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 ...

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] |
