EIF6
Eukaryotic translation initiation factor 6 (EIF6), also known as Integrin beta 4 binding protein (ITGB4BP), is a human gene. Hemidesmosomes are structures which link the basal lamina to the intermediate filament cytoskeleton. An important functional component of hemidesmosomes is the integrin beta-4 subunit (ITGB4), a protein containing two fibronectin type III domains. The protein encoded by this gene binds to the fibronectin type III domains of ITGB4 and may help link ITGB4 to the intermediate filament cytoskeleton. The encoded protein, which is insoluble and found both in the Cell nucleus, nucleus and in the cytoplasm, can function as a eukaryotic initiation factor, translation initiation factor and catalyzes the association of the 40S and 60S ribosome, ribosomal subunits along with eIF5 bound to GTP. Multiple transcript variants encoding several different protein isoform, isoforms have been found for this gene. EIF6 plays important roles in Eukaryotic 80S ribosome formation, c ...

Eukaryotic Initiation Factor
Eukaryotic initiation factors (eIFs) are Protein, proteins or Protein complex, protein complexes involved in the initiation phase of eukaryotic translation. These proteins help stabilize the formation of ribosomal preinitiation complexes around the start codon and are an important input for Post-transcriptional regulation, post-transcription gene regulation. Several initiation factors form a complex with the small 40S ribosomal subunit and Met-tRNAiMet called the 43S preinitiation complex (43S PIC). Additional factors of the eIF4F complex (eIF4A, E, and G) recruit the 43S PIC to the five-prime cap structure of the mRNA, from which the 43S particle scans 5'-->3' along the mRNA to reach an AUG start codon. Recognition of the start codon by the Met-tRNAiMet promotes gated phosphate and eIF1 release to form the 48S preinitiation complex (48S PIC), followed by large 60S ribosomal subunit recruitment to form the Eukaryotic ribosome (80S), 80S ribosome. There exist many more eukaryotic ini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GNB2L1
Receptor for activated C kinase 1 (RACK1), also known as guanine nucleotide-binding protein subunit beta-2-like 1 (GNB2L1), is a 35 kDa protein that in humans is encoded by the RACK1 gene. Function RACK1 was originally isolated and identified as an intracellular protein receptor for protein kinase C, noting the significant homology to the beta subunit of heterotrimeric G proteins. Later studies established RACK1, and its yeast homolog Asc1, as a core ribosomal protein of the eukaryotic small (40S) ribosomal subunit. Much of the function of Asc1/RACK1 appears to result from its position on the 'head' of the 40S ribosomal subunit. Asc1/RACK1 participates in several aspects of eukaryotic translation and ribosome quality control, including IRES-mediated translation, non-stop decay, non-functional 18S ribosomal RNA decay, and frameshifting. Interactions RACK1 is positioned at the solvent-exposed surface of the 40S ribosomal subunit, where it is held in place through contact ...

Ribosome
Ribosomes ( ) are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the ''translational apparatus''. Overview The sequence of DNA that encodes the sequence of the amino acids in a protein is transcribed into a messenger RNA chain. Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of amino acids to generate a given protein. Amino acids are selected and carried to the ribosome by transfer RNA (tRNA) molecules, which enter the ribosome and bind to the messenger RNA chain via an anti-c ...

Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code. Amino acids can be classified according to the locations of the core structural functional groups, as Alpha and beta carbon, alpha- , beta- , gamma- or delta- amino acids; other categories relate to Chemical polarity, polarity, ionization, and side chain group type (aliphatic, Open-chain compound, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Carlo Marchisio
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 gene– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FHL2
Four and a half LIM domains protein 2 also known as FHL-2 is a protein that in humans is encoded by the ''FHL2'' gene. LIM proteins contain a highly conserved double zinc finger motif called the LIM domain. Function FHL-2 is thought to have a role in the assembly of extracellular membranes and may function as a link between presenilin-2 and an intracellular signaling pathway. Family The Four-and-a-half LIM (FHL)-only protein subfamily is one of the members of the LIM-only protein family. Protein members within the group might be originated from a common ancestor and share a high degree of similarity in their amino acid sequence. These proteins are defined by the presence of the four and a half cysteine-rich LIM homeodomain with the half-domain always located in the N-terminal. The name LIM was derived from the first letter of the transcription factors LIN-11, ISL-1 and MEC-3, from which the domain was originally characterized. No direct interactions between LIM domain and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
