Trans splicing is a special form of Messenger RNARNA processing in eukaryote s where exon s from two different primary RNA transcripts are joined end to end and Ligase ligated . In contrast normal splicing genetics cis splicing processes a single molecule. That is, trans splicing results in an RNA transcript that came from multiple RNA polymerases on the genome. This phenomenon can be exploited for molecular therapy to address mutated gene products. Trans splicing can be the mechanism behind certain oncogenic fusion transcript s. ref cite journal year 2008 title A neoplastic gene fusion mimics trans splicing of RNAs in normal human cells pmid 18772439 author Li et al. postscript None doi 10.1126 science.1156725 ref ref cite journal year 2009 title SLC45A3 ELK4 is a novel and frequent erythroblast transformation specific fusion transcript in prostate cancer pmid 19293179 author Rickman et al. postscript None doi 10.1158 0008 5472.CAN 08 4926 ref Trans splicing is used by certain microbial organisms, notably protozoa of the Kinetoplastid Kinetoplastae class to produce variable surface antigens and change from one life stage to another.

Protein splicing is an intramolecular reaction of a particular protein in which an internal protein segment called an intein is removed from a precursor protein with a ligation of C terminal and N terminal external proteins called extein s on both sides. The splicing junction of the precursor protein is mainly a cysteine or a serine , which are amino acid s containing a nucleophilic side chain . The protein splicing reactions which are known now do not require exogenous cofactors or energy sources such as adenosine triphosphate ATP or guanosine triphosphate GTP . Normally, splicing is associated only with Splicing genetics pre mRNA splicing . Types of inteins The type of the splicing proteins is categorized into four classes maxi intein, mini intein, trans splicing intein, and alanine intein. The maxi inteins are N and C terminal splicing domains containing an endonuclease domain. The mini inteins are typical N and C terminal splicing domains however, the endonuclease domain is not present. The trans splicing inteins are split inteins which are divided into N termini and C termini. Alanine inteins have the splicing junction of an alanine instead of a cysteine or a serine, in both of which the protein splicing occurs. History Protein splicing was reported by two groups Anraku and Stevens in 1990. They both discovered a Saccharomyces cerevisiae VMA1 in a precursor of a vacuolar H sup sup ATPase . The amino acid sequence of the N and C termini corresponded to 70 of that of a vacuolar H sup sup ATPase from other organisms, while the amino acid sequence of the central position corresponded to 30 of that of the yeast HO nuclease External links http starokadomskyy.narod.ru work intein eng.html Short review http starokadomskyy.narod.ru Protein splicing eng.pdf Starokadomskyy PL.

File Core alignment splicer by Ilsintech.png thumb upright A modern fusion splicer Fusion splicing is the act of joining two optical fiber s end to end using heat. The goal is to fuse the two fibers together in such a way that light passing through the fibers is not scattering scattered or Reflection physics reflected back by the splice, and so that the splice and the region surrounding it are almost as strong as the virgin fiber itself. The source of heat is usually an electric arc , but can also be a laser, or a gas flame, or a Electrical filament tungsten filament through which electric current current is passed. The process of fusion splicing involves using localized heat to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion. Fusion splicing requires that all protective coatings be removed from the ends of each fiber, a process called stripping fiber stripping . The fiber is then Cleave fiber cleaved using the score ....

An exonic splicing enhancer ESE is a DNA sequence motif consisting of 6 bases within an exon that directs, or enhances, accurate splicing genetics splicing of hetero nuclear RNA hnRNA or pre mRNA into messenger RNA mRNA . The Basics The central dogma of molecular biology states that all of the information that makes you unique is housed in the cell nucleus nucleus of every cell biology cell in your body in the form of DNA . The human DNA is a string of 3.2 billion base pairs . Short sequences of DNA are transcribed to RNA then this RNA is translated to a protein . A gene located in the DNA will contain introns and exons . Part of the process of preparing the RNA includes splicing genetics splicing out the introns, sections of RNA that do not code for protein. The presence of exonic splicing enhancers is essential for proper identification of splice sites by the cellular machinery. Research Computational methods were used to identify 238 candidate ESEs. ESEs are clinically significant because synonymous point mutations previously thought to be silent mutations located in an ESEs can lead to exon skipping and the production of a non functioning protein.
