APPRIS - A system for annotating alternative splice isoforms

Primary LanguagePerl

Welcome to APPRIS - A system for annotating alternative splice isoforms
=======================================================================
APPRIS [1] is a system that deploys a range of computational methods to provide value to the annotations of the human genome. APPRIS also selects one of the CDS for each gene as the principal isoform.

APPRIS defines the principal variant by combining protein structural and functional information and information from the conservation of related species.

The server has been used in the context of the scale up of the GENCODE (http://www.gencodegenes.org/, a sub-project of the ENCODE) project to annotate the Human genome but APPRIS is being used for other species:
	* Human
	* Mouse
	* Rat
	* Zebrafish


System overview
===============
The goals of the APPRIS system are to annotate alternative variants with reliable biological data and to select the primary variant for each gene. APPRIS is based on a range of complementary computational methods.

The methods in APPRIS are the following:
	== Functionally important residues, firestar
	== Protein structural information, Matador3D
	== Presence of whole protein domains, SPADE
	== Conservation against vertebrates, CORSAIR
	== Presence of whole trans-membrane helices, THUMP
	== Prediction of signal peptide and sub-cellular location, CRASH
	== Selective pressure evolution of exons, INERTIA [Note: Currently, this method is not affecting in the selection of the principal isoform]


Data access
===========
The APPRIS websites offer an export option, suitable for small amounts of data. This is the ideal option if you want a protein sequence as a FASTA file, or a JSON/GTF file of a few features of a gene or transcript. Furthermore, you can get annotation tracks of gene/transcripts in the BED format. Simply click on one of the "Export" links in the right menu, and select the output options. If you wish to extract multiple features, we recommend the following alternatives.

== Perl API Documentation, APPRIS data can be accessed remotely using our Perl API to connect to a public database server.
