What is ESEfinder?
ESEfinder (http://exon.cshl.edu/ESE/) is a web-based resource that facilitates rapid analysis of exon sequences to identify putative ESEs responsive to the human SR proteins SF2/ASF, SC35, SRp40 and SRp55, and to predict whether exonic mutations disrupt such elements.
What is canonical splice site?
The canonical splice sites are those originally described and most commonly found (like in ~99% of introns) and have GT at the donor site (just after the 5′ end of the cut) and AG at the acceptor site (just before the 3′ end of the cut).
How do you know if a website is splicing?
Introns are removed from primary transcripts by cleavage at conserved sequences called splice sites. These sites are found at the 5′ and 3′ ends of introns. Most commonly, the RNA sequence that is removed begins with the dinucleotide GU at its 5′ end, and ends with AG at its 3′ end.
What controls alternative splicing?
Splicing is regulated by trans-acting proteins (repressors and activators) and corresponding cis-acting regulatory sites (silencers and enhancers) on the pre-mRNA. However, as part of the complexity of alternative splicing, it is noted that the effects of a splicing factor are frequently position-dependent.
Where are introns found?
Introns are found in the genes of most organisms and many viruses and they can be located in both protein-coding genes and genes that function as RNA (noncoding genes).
What is a cryptic exon?
Cryptic exons are considered splicing variants that may introduce frameshifts or stop codons, among other changes in the resulting mRNA. These aberrant mRNA have been demonstrated in motor cortex and middle temporal gyrus of ALS and FTLD patients .
What is a non canonical splice site?
Non-canonical splicing events are often tissue-specific and are particularly enriched in the central nervous system, thereby increasing proteome diversity or regulating gene expression. Cryptic exons, microexons and recursive splice sites often require unconventional exon definition mechanisms.
How do Snrnas work?
The snRNA component of the snRNP gives specificity to individual introns by “recognizing” the sequences of critical splicing signals at the 5′ and 3′ ends and branch site of introns. The snRNA in snRNPs is similar to ribosomal RNA in that it directly incorporates both an enzymatic and a structural role.
What is the difference between splicing and alternative splicing?
The main difference between RNA splicing and alternative splicing is that the RNA splicing is the process of splicing the exons of the primary transcript of mRNA whereas the alternative splicing is the process of producing differential combinations of exons of the same gene.
What is the consequence of alternative splicing?
The consequences of an alternative splicing are the deletion or the insertion of a nucleic acid sequence that might modify the protein sequence encoded by the gene.
What is the benefit of introns?
Introns are crucial because the protein repertoire or variety is greatly enhanced by alternative splicing in which introns take partly important roles. Alternative splicing is a controlled molecular mechanism producing multiple variant proteins from a single gene in a eukaryotic cell.
How are the results displayed in esefinder?
In html format, the result of each sequence is displayed separately, each has three sections Since release 2.0, ESEfinder allows to direct graphical display of the results the analyzed (exonic) sequence is reproduced along the X-axis. only the high-score values (the values above the selected threshold) are represented
What’s new in esefinder 3?
To improve performance, the total size of query sequences in a submission is limited to 5000 nucelotides, no matter it is in a single sequence or in multiple sequences. ESEfinder 3.0 has made a number changes in the output format. In the first page, the user can choose to generate output in either html format or plain text format.

Is ESET a good malware scanner?
ESET’s malware scanner is really advanced. It uses heuristics and machine learning to identify malware, and its cloud-based scanning barely slowed down my computer, even during full system scans. ESET also offers some decent extra features, like device encryption, advanced diagnostic tools, and anti-theft protection.
