We recently reported that spliceosomes alter messenger ribonucleoprotein particle (mRNP) composition by depositing several proteins 20-24 nucleotides upstream of mRNA exon-exon junctions. When assembled in vitro, this so-called exon-exon junction complex (EJC) contains at least five proteins: SRm1 …

Four separate CETP gene mutations have been published previously. Of the four mutations, the intron 14 donor splice site mutation4 and the Asp442-to-Gly mutation in exon 1528 are both known to be very common in the Japanese population.7 8 9 10 29 The other two mutations, the Gln309-to-Stop mutation in exon 1026 and a 1-bp insertion in intron 14,7 are probably sporadic mutations. Except for the Asp442-to-Gly mutation that causes partial CETP deficiency, the other three seemed to have null allelic effects, although exact mechanisms underlying the null effects have not been studied. In the present study, we demonstrated that the primary abnormality due to the intron 14 donor splice site mutation is the exon skipping of mRNA, which decreases the level of mRNA and produces a truncated protein that should be degraded intracellularly. These observations clearly explain the molecular basis of the complete CETP deficiency found not only in patients with the common intron 14 splicing mutation but also in ...

Somatically acquired mutations in components of the RNA processing pathway in CLL. Presented is an overview illustrating the individual components of the RNA-processing pathway, with those components identified as being somatically mutated highlighted (*) and the mutated protein listed in red. Initially, nascent pre-mRNA transcripts undergo 5′ capping and binding of the cap-binding complex (CBC), followed by the formation of the major spliceosome, the machinery responsible for the removal of pre-mRNA introns via a stepwise mechanism. Initial assembly steps include formation of pre-spliceosome complex A (top left nuclear complex) involving recognition of the 5′ splice site by U1 snRNP (an interaction stabilized by members of the serine-arginine-rich (SR) protein family) and recognition of the 3′ SS region by the U2 Auxiliary factor U2AF and by U2snRNP. U2AF binds to the intronic polypyrimidine tract and 3′SS, and facilitates binding of U2 snRNP to the branch-point sequence. Stable U2 ...

DNA- and RNA binding protein, involved in several nuclear processes. Essential pre-mRNA splicing factor required early in spliceosome formation and for splicing catalytic step II, probably as a heteromer with NONO. Binds to pre-mRNA in spliceosome C complex, and specifically binds to intronic polypyrimidine tracts. Involved in regulation of signal-induced alternative splicing. During splicing of PTPRC/CD45, a phosphorylated form is sequestered by THRAP3 from the pre-mRNA in resting T-cells; T-cell activation and subsequent reduced phosphorylation is proposed to lead to release from THRAP3 allowing binding to pre-mRNA splicing regulatotry elements which represses exon inclusion. Interacts with U5 snRNA, probably by binding to a purine-rich sequence located on the 3 side of U5 snRNA stem 1b. May be involved in a pre-mRNA coupled splicing and polyadenylation process as component of a snRNP-free complex with SNRPA/U1A. The SFPQ-NONO heteromer associated with MATR3 may play a role in nuclear ...

The SRPK category of kinases regulates pre-mRNA splicing by phosphorylating serine/arginine (SR)-rich splicing factors, signals splicing control in response to extracellular stimuli, and plays a part in tumorigenesis, suggesting these splicing kinases are potential therapeutic targets. for treatment of age-related macular degeneration. In Short Hatcher et al. statement the 1st irreversible SRPK1/2 inhibitor SRPKIN-1, which inhibits phosphorylation of serine/arginine (SR)-wealthy splicing elements proteins and induces a VEGF alternate splicing isoform change, resulting in anti-angiogenesis inside a damp CNV mouse model.

Plays a role in preventing exon skipping, ensuring the accuracy of splicing and regulating alternative splicing. Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5- and 3-splice site binding components, U1 snRNP and U2AF. Can stimulate binding of U1 snRNP to a 5-splice site-containing pre-mRNA. Binds to purine-rich RNA sequences, either the octamer, 5-RGAAGAAC-3 (r=A or G) or the decamers, AGGACAGAGC/AGGACGAAGC. Binds preferentially to the 5-CGAGGCG-3 motif in vitro. Three copies of the octamer constitute a powerful splicing enhancer in vitro, the ASF/SF2 splicing enhancer (ASE) which can specifically activate ASE-dependent splicing. Isoform ASF-2 and isoform ASF-3 act as splicing repressors. May function as export adapter involved in mRNA nuclear export through the TAP/NXF1 pathway ...

This sequence change falls in intron 14 of the PNKP gene. It does not directly change the encoded amino acid sequence of the PNKP protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is present in population databases (rs776617733, ExAC 0.04%). This variant has not been reported in the literature in individuals with PNKP-related conditions. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance ...

A splice site mutation is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing takes place during the processing of precursor messenger RNA into mature messenger RNA. Splice site consensus sequences that drive exon recognition are located at the very termini of introns. The deletion of the splicing site results in one or more introns remaining in mature mRNA and may lead to the production of abnormal proteins. When a splice site mutation occurs, the mRNA transcript possesses information from these introns that normally should not be included. Introns are supposed to be removed, while the exons are expressed. The mutation must occur at the specific site at which intron splicing occurs: within non-coding sites in a gene, directly next to the location of the exon. The mutation can be an insertion, deletion, frame shift, etc. The splicing process itself is controlled by the given sequences, known as splice-donor and splice-acceptor ...

The current model of spliceosome assembly was developed principally from the in vitro pattern of small nuclear ribonucleoprotein (snRNP) particle association with synthetic splicing substrates (reviewed in Moore et al., 1993; Madhani and Guthrie, 1994; Krämer, 1996). In mammals and yeast, spliceosome assembly progresses by the sequential addition of the U1 snRNP→U2 snRNP→U4/U6.U5 tri‐snRNP particles to the pre‐mRNA. Before 5′ splice‐site cleavage (chemical step I in splicing), the affinities of the U1 and U4 snRNAs for the splicing complex are greatly reduced and, under many (Pikielny et al., 1986; Cheng and Abelson, 1987; Konarska and Sharp, 1987) although not all (Blencowe et al., 1989) isolation conditions, the U4 snRNA is lost from the spliceosome. This model of spliceosome assembly is supported by the abridged spliceosome assembly profiles observed when splicing is inhibited by specific mutations in the pre‐mRNA or when one of the many trans‐acting components of splicing is ...

We have characterized two RNA-binding proteins, of apparent molecular masses of approximately 40 and 35 kDa, which possess a single N-terminal RNA-recognition motif (RRM) followed by a C-terminal domain rich in serine-arginine dipeptides. Their primary structures resemble the single-RRM serine-arginine (SR) protein, SC35; however their functional effects are quite distinctive. The 40-kDa protein cannot complement SR protein-deficient HeLa cell S100 extract and showed a dominant negative effect in vitro against the authentic SR proteins, SF2/ASF and SC35. Interestingly, the 40- and 35-kDa proteins antagonize SR proteins and activate the most distal alternative 5 splice site of adenovirus E1A pre-mRNA in vivo, an activity that is similar to that characterized previously for the heterogeneous nuclear ribonucleoprotein particles A/B group of proteins. A series of recombinant chimeric proteins consisting of domains from these proteins and SC35 in various combinations showed that the RRM, but not the C

Pre-mRNA splicing takes place in an RNA machine known as the spliceosome, which consists of small nuclear ribonucleoprotein particles (snRNPs)1 and non-snRNP protein factors. The RNA components in the spliceosome form the catalytic core through a series of dynamic RNA-RNA interactions which are likely to be mediated and/or stabilized by non-snRNP protein factors (for recent reviews see Nilsen, 1998; Staley and Guthrie, 1998). Among the best characterized non-snRNP splicing factors are SR proteins which contain one or two RNA recognition motifs and a signature RS domain containing multiple serine and arginine repeats (for reviews see Fu, 1995; Manley and Tacke, 1996). The RNA recognition motifs bind to RNA sequences in a coordinated fashion to determine splicing specificity (Chandler et al., 1997) and commit pre-mRNA substrates to the splicing pathway (Fu, 1993), whereas the RS domains mediate specific protein- protein interactions in a number of spliceosomal assembly steps (Wu and Maniatis, ...

During spliceosome assembly, protein-protein interactions (PPI) are sequentially formed and disrupted to accommodate the spatial requirements of pre-mRNA substrate recognition and catalysis. Splicing activators and repressors, such as SR proteins and hnRNPs, modulate spliceosome assembly and regulate alternative splicing. However, it remains unclear how they differentially interact with the core spliceosome to perform their functions. Here, we investigate the protein connectivity of SR and hnRNP proteins to the core spliceosome using probabilistic network reconstruction based on the integration of interactome and gene expression data. We validate our model by immunoprecipitation and mass spectrometry of the prototypical splicing factors SRSF1 and hnRNPA1. Network analysis reveals that a factors properties as an activator or repressor can be predicted from its overall connectivity to the rest of the spliceosome. In addition, we discover and experimentally validate PPIs between the oncoprotein SRSF1 and

Many functional RNAs are required to fold into specific three-dimensional structures. A fundamental property of RNA is that its secondary structure and even some tertiary contacts are highly stable, which gives rise to independent modular RNA motifs and makes RNAs prone to adopting misfolded intermediates. Consequently, in addition to stabilizing the native structure relative to the unfolded species (defined here as stability), RNAs are faced with the challenge of stabilizing the native structure relative to alternative structures (defined as structural specificity). How RNAs have evolved to overcome these challenges is incompletely understood. Self-splicing group I introns have been used to study RNA structure and folding for decades. Among them, the Tetrahymena intron was the first discovered and has been studied extensively. In this work, we found that a version of the intron that was generated by in vitro selection for enhanced stability also displayed enhanced specificity against a stable ...

Assembly of the spliceosome by the stepwise binding of the snRNPs to the pre-mRNA. In the early phase of spliceosome assembly, the U1 snRNP binds to the 5 splice site (5 SS: where exon 1 ends and the intron begins), and the U2 snRNP binds to the so-called branch point (BP: near the 3 end of the intron). This spliceosome assembly intermediate is called the A complex. The subsequent binding of the U4/U6.U5 tri snRNP complex gives rise to the precatalytic B complex. The catalytic activation of the spliceosome takes place in two steps. In the first, the RNA helicase Brr2 acts to produce the Bact complex and in the second, the RNA helicase Prp2 facilitates the formation of the B* complex. This has a functional active site and, following the recruitment of the protein Cwc25, the first step of splicing takes place. In this step, the phosphodiester bond at the 5 splice site is cleaved and, at the same time, the 5 end of the intron becomes linked to the 2 hydroxyl group of an adenosine at the ...

A tripartite motif located in the centre of the 7.5kb exon 26 of apolipoprotein B (apoB) mRNA directs editosome assembly and site-specific cytidine-to-uridine editing at nucleotide 6666. apoB mRNA editing is a post-transcriptional event, occurring primarily at the time exon 26 is spliced or at a time after splicing, but before nuclear export. We show, through reporter RNA constructs, that RNA splice sites suppress editing of precursor RNAs when placed proximal or distal to the editing site. Processed RNAs were edited more efficiently than precursor RNAs. Mutation of both the splice donor and acceptor sites was necessary for RNAs to be edited efficiently. The results suggested that commitment of pre-mRNA to the splicing and/or nuclear-export pathways may play a role in regulating editing-site utilization. The HIV-1 Rev-Rev response element (RRE) interaction was utilized to uncouple the commitment of precursor RNAs to the spliceosome assembly pathway and associated nuclear-export pathway. Under ...

Lucero Rogel. PREP Program. Lab Group: Alan Zahler. PREP Research: The Zahler lab works to investigate the mechanism of RNA splicing by utilizing C. elegans as a model organism. Accurate splicing of pre-mRNA is a critical step in the gene expression pathway in eukaryotes carried out by a large ribonucleoprotein complex known as the spliceosome. The spliceosome consists of 5 RNAs (U1, U2, U4, U5, and U6) that assemble onto the pre-mRNA by recognizing conserved sequence elements that define the beginning and ends of introns, known as 5 and 3 splice sites. To facilitate the interactions between the pre-mRNA and the 5 RNAs, over 150 proteins are employed to aid in the process. Currently in the lab, I am working on elucidating the role of spliceosomal protein SNRP-27 in 5 splice site selection by uncovering differential interactions that a mutant and wild type form of this factor have with the splicing machinery..

This sequence change affects codon 6 of the SLC2A1 mRNA. It is a silent change, meaning that it does not change the encoded amino acid sequence of the SLC2A1 protein. This variant also falls at the last nucleotide of exon 1 of the SLC2A1 coding sequence, which is part of the consensus splice site for this exon. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has not been reported in the literature in individuals with SLC2A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 378602). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional ...

HI! Tetrahymena RNA self-splices and does it in a very specific series of steps. You find an RNA that self-splices in the same way. It also loops before splicing and the 5 end of the intron to the 3 end of the exon. You were able to figure out the six nucleotide sequence of the 3 end of the exon. Reading 5 to 3, what is the sequence of the base-pairing nucleotides on the intron starting at position #1? 5 TTTCGG 3 (No, this is a DNA sequence.) 5 GGCUUU 3 (No, this is the right sequence but it is in the wrong direction.) 5 GGCTTT 3 (No, this is a DNA sequence.) 5 UUUCGG 3 (That is correct.) G can hydrogen bond with C, and A can hydrogen bond with U. Reading 5 to 3 the complementary sequence is UUUCGG. You think that this base pairing is important for the self-splicing reaction. To prove this theory, you insert two Uracils into the intron and you find that self-splicing decreases dramatically. Other than deleting the 2 Us, how might you restore the self-splicing reaction to this RNA? ...

Splicing factors of the SR protein family share a modular structure consisting of one or two RNA recognition motifs (RRMs) and a C-terminal RS domain rich in arginine and serine residues. The RS domain, which is extensively phosphorylated, promotes protein-protein interactions and directs subcellular localization and-in certain situations-nucleocytoplasmic shuttling of individual SR proteins. We analyzed mutant versions of human SF2/ASF in which the natural RS repeats were replaced by RD or RE repeats and compared the splicing and subcellular localization properties of these proteins to those of SF2/ASF lacking the entire RS domain or possessing a minimal RS domain consisting of 10 consecutive RS dipeptides (RS10). In vitro splicing of a pre-mRNA that requires an RS domain could take place when the mutant RD, RE, or RS10 domain replaced the natural domain. The RS10 version of SF2/ASF shuttled between the nucleus and the cytoplasm in the same manner as the wild-type protein, suggesting that a ...

It almost sounds like a made up word, but the spliceosome is a very real and very complex molecular machine in the nucleus of cells, and its at the center of some exciting new Kimmel Cancer Center research.. Its job is to chop up genes so that proteins can be transcribed into cellular actions. If a spliceosome gene is mutated in a cancer, it sometimes leads to more gene mutations. These mutations may make cells look different and could attract T cells, so we are exploring spliceosome mutations as a marker for response to immunotherapy, says breast cancer researcher Natasha Hunter.. Spliceosome mutations are rare, occurring in a small fraction of cancers, including about four percent of breast cancers and about 19 percent of melanomas. Studies led by Brian Dalton revealed them as a prognosis indicator for patients with hematologic malignancies, but this new research is one of the first attempts to use them as a therapeutic target.. In conjunction with the GAITWAY Tumor Board, Hunter is leading ...

The SR proteins constitute a large family of nuclear phosphoproteins required for constitutive pre-mRNA splicing. These factors also have global, concentration-dependent effects on alternative splicing regulation and this activity is antagonized by members of the hnRNP A/B family of proteins. We show here that whereas some human SR proteins are confined to the nucleus, three of them-SF2/ASF, SRp20, and 9G8-shuttle rapidly and continuously between the nucleus and the cytoplasm. By swapping the corresponding domains between shuttling and nonshuttling SR proteins, we show that the carboxy-terminal arginine/serine-rich (RS) domain is required for shuttling. This domain, however, is not sufficient to promote shuttling of an unrelated protein reporter, suggesting that stable RNA binding mediated by the RNA-recognition motifs may be required for shuttling. Consistent with such a requirement, a double point-mutation in RRM1 of SF2/ASF that impairs RNA binding prevents the protein from shuttling. In addition, we

Gene Information This gene encodes one of four subunits of the splicing factor 3B. The protein encoded by this gene cross-links to a region in the pre-mRNA immediately upstream of the branchpoint sequence in pre-mRNA in the prespliceosomal complex A. It also may be involved in the assembly of the B C and E spliceosomal complexes. In addition to RNA-binding activity this protein interacts directly and highly specifically with subunit 2 of the splicing factor 3B. This protein contains two N-terminal RNA-recognition motifs (RRMs) consistent with the observation that it binds directly to pre-mRNA. [provided by RefSeq Jul 2008]. ...

During pre-mRNA splicing, exons in the primary transcript are precisely connected to generate an mRNA. Intron lariat RNAs are formed as by-products of this process. In addition, some exonic circular RNAs (circRNAs) may also result from exon skipping as by-products. Lariat RNAs and circRNAs are both RNase R resistant RNAs. RNase R is a strong 3 to 5 exoribonuclease, which efficiently degrades linear RNAs, such as mRNAs and rRNAs; therefore, the circular parts of lariat RNAs and the circRNAs can be segregated from eukaryotic total RNAs by their RNase R resistance. Thus, RNase R resistant RNAs could provide unexplored splicing information not available from mRNAs. Analyses of these RNAs identified repeating splicing phenomena, such as re-splicing of mature mRNAs and nested splicing. Moreover, circRNA might function as microRNA sponges. There is an enormous variety of endogenous circRNAs, which are generally synthesized in cells and tissues.

Several predictions come out of these models including the lack of introns in the 3′ UTR and that the average length of exons should be correlated with the window that the proofreading mechanism can operate on. These are discussed in several papers out of Mike Lynchs lab including (Lynch and Connery 2003), (Lynch and Kewalramani, 2003), (Lynch and Richardson, 2002) and recently (Scofield et al, 2007).. Efforts to understand the splicing machinery, particularly in S. cerevisiae have led to the discovery of numerous genes that code for proteins that make up the spliceosome. Some of these include small RNAs as well as protein coding genes. The SR proteins are serine-arginine rich proteins that regulate splicing and are found in almost all eukaryotes including most fungi (even those with few introns, such as S. cerevisiae). SR proteins play a role in splicing and in nuclear export (Masuyama et al, 2004, Sanford et al, 2004) indicating that a coupling of these processes may explain why genes with ...
