This track shows AceView gene models constructed from mRNA, EST and genomic evidence by Danielle and Jean Thierry-Mieg and Vahan Simonyan using the Acembly program.
This track follows the display conventions for gene prediction tracks. Gene models that fall into the "main" prediction class are displayed in purple; "putative" genes are displayed in pink.
The track description page offers the following filter and configuration options:
AceView attempts to find the best alignment of each mRNA/EST against the genome, and clusters the alignments into the least possible number of alternatively spliced transcripts. The reconstructed transcripts are then clustered into genes by simple transitive contact. To see the evidence that supports each transcript, click the "Outside Link" on an individual transcript's details page to access the NCBI AceView web site.
Each AceView transcript model has a gene cluster designation (alternate name) that is categorized into a prediction class of either main or putative.
Prediction Class: main
Class of genes that includes the protein coding genes (defined
here by CDS > 100 amino acids) and all genes with at least one
well-defined standard intron, i.e., an intron with a GT-AG or GC-AG
boundary, supported by at least one clone matching exactly, with
no ambiguous bases, and the 8 bases on either side of the intron
identical to the genome. Genes with a CDS smaller than 100 amino acids are
included in this class if they meet one of the following conditions: they
have a NCBI RefSeq sequence (NM_#) or an OMIM identifier, or they encode a
protein with BlastP homology (< 1e-3) to a cDNA-supported nematode AceView
protein.
Prediction Class: putative
Class of genes that have no standard intron and do not
encode CDS of more than 100 amino acids, yet may be sufficiently useful to
justify not disregarding them completely. Putative genes may be of two
types: either those supported by more than six cDNA clones or those that
encode a putative protein with an interesting annotation. Examples include
a PFAM motif, a BlastP hit to a species other than itself (< 1e-3),
a transmembrane domain or other rare and meaningful domains
identified by Psort2, or a highly probable localization in a cell
compartment (excluding cytoplasm and nucleus).
