Search Interface

Splicing Factor The user can search information about a specific splicing factor by entering its protein name, e.g "SC35".
Gene The user can search information about a specific splicing factor by entering its encoding-gene name, e.g "SFRS2". In order to retrieve its binding/no-binding sites click on splicing factor name in result table. Search for "Splicing Factor" or its encoding "Gene" is mutually exclusive.
Binding site lengthThe user can use the length of binding (and not binding) sites to filter the query. The default values are the minimum and the maximum lengths among all SpliceAid-F sequences.
SF binding sites in The user can search information, by selecting a specific organism/genome where a human splicing factor binding or activity has been assessed. For example, besides human, user can search for binding/no-binding sites in mouse, rat, rabbit, HIV-1 and so on.
Target chromosome The user can retrieve all binding/no-binding sites lying in a selected target chromosome. It is possible to enter, for example, both the terms "chr4" or only "4" to retrieve all binding sites (and not binding sites) lying in chromosome 4.
Target Gene/Element The user can retrieve all binding/no-binding sites lying in a selected target gene, element or synthetic sequences. In case of genes with the same name across species, e.g CSF2 is referred both to Human and Mouse, results for all possible species will be reported in the result table.
Activity The user can retrieve the binding sites where the binding of a splicing factor induce a specific splicing activity. "Exon definition" and "Intron definition" imply that the splicing factor activity is addressed to the pre-mRNA tract where the binding site lies, whereas other activities as, for example, "Intron definition of upstream and downstream sequences" mean that splicing factor activity concern other pre-mRNA tracts.
Localization The user can search information by selecting a specific genetic localization of the assessed binding site of a splicing factor, e.g in an exon or intron, near to an Exon/Intron boundary (near a 3'ss or a 5'ss), or in the 3'UTR or 5'UTR. The term "Intron/Exon" means that the binding/no-binding site lies in a tract straddling on an exon/intron boundary.

Result Page

In the Result Page, the number of splicing factors, binding sites and not-binding sites are reported.
Moreover, user can download the obtained results, exporting them in tab-delimited format.
To refine the results, it is possible to use again the Search form.

Binding Sites / No binding evidences Tables

Shaded rows are related to sites without binding activity in a specific context or type of assay that contain a binding site for the same splicing factor.

Sequence OligoSequence of the site with or without binding activity for the selected splicing factor.
ScoreA positive score (+1...+10) was assigned to the target sequences that facilitate exon definition that is ESE (exonic splicing enhancer) and ISS (intronic splicing silencer) motifs. According to the same criteria we assigned a negative score (-1...-10) to the target sequences that facilitate intron definition that is ESS (exonic splicing silencer) and ISE (intronic splicing enhancer) motifs. The binding site score is related to the binding affinity deduced from the related reference.
Target Gene/ElementGene name or element where the binding site lies. A link to NCBI is provided.
StatusIf the gene is mutated, it is reported.
Target OrganismThe specific organism where the human splicing factor binding or activity has been assessed.
Cell lineCell line or tissue type where the human splicing factor binding or activity has been assessed.
Splicing AssayType of splicing assay used in the related article.
Binding AssayType of binding assay used in the related article.
CoordinatesCoordinates of the binding site according to Human hg18 assembly, that is NCBI Build 36.1 (March 2006). Moreover, we used for mouse NCBI37/mm9, for rat Baylor 3.4/rn4, for rabbit Broad/oryCun2, ICGSC Gallus_gallus-4.0/galGal4, for D. melanogaster BDGP R5/dm3 and for S. cerevisiae SacCer_Apr2011/sacCer3 assemblies.
ActivityThe specific assessed splicing activity of the splicing factor.
LocalizationThe genetic localization of the assessed binding site of the splicing factor.
Disease correlationDisease associated to the binding site alteration (provided by OMIM database and cross-linked to it).
ReferencePubMed ID (PMID) and the year of publication. By clicking on it, user can come back to the reference experimentally supporting the binding and download the article from PubMed database at NCBI.
ASPicDBLink to ASPicDB results page, reporting the whole set of information available for the gene in such database. ASPicDB is a database designed to provide access to reliable annotations of the alternative splicing pattern of genes, obtained by ASPic algorithm (Castrignano' et al. 2006), and to the functional annotation of predicted isoforms.
