SUMMARY back to top
Summary
[Wormbase] gly-3 encodes an N-acetylgalactosaminyltransferase that is functional in vitro.
Wormbase predicts one model, but Caenorhabditis elegans cDNA sequences in GenBank, dbEST, Trace and SRA, filtered against clone rearrangements, coaligned on the genome and clustered in a minimal non-redundant way by the manually supervised AceView program, support at least 3 spliced variants

AceView synopsis, each blue text links to tables and details
Expression: According to AceView, this gene is expressed at very high level, 5.2 times the average gene in this release, mostly from L1 larvae to adult [Kohara cDNAs]. The expression profile for the gene, derived from the proportion of animals at each stage in each Kohara library is: embryos 3%, L1 or L2 larvae 51%, L3 to adult (including dauer) 46%. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 39 cDNA clones and 29 elements defined by RNA-seq, some from l2 (seen 16 times), l1 (6), mixed (4), l4 (3), embryo (once). We annotate structural defects or features in 6 cDNA clones.
Alternative mRNA variants and regulation: The gene contains 8 distinct gt-ag introns. Transcription produces 3 alternatively spliced mRNAs. Variant a is transpliced to SL2, SL7, SL3, SL4, SL11. There are 5 validated alternative polyadenylation sites (see the diagram). The mRNAs appear to differ by presence or absence of a cassette exon, overlapping exons with different boundaries.
Function: There are 2 articles specifically referring to this gene in PubMed. In addition we point below to 2 abstracts. Proteins are expected to localize in membrane. No phenotype has yet been reported to our knowledge: this gene's in vivo function is yet unknown.
Protein coding potential: The 3 spliced mRNAs putatively encode good proteins, altogether 3 different isoforms (1 complete, 1 COOH complete, 1 partial), some containing domains Glycosyl transferase, family 2, ricin B lectin [Pfam].

Compact gene diagram back to top
Alternative mRNAs are shown aligned from 5' to 3' on a virtual genome where introns have been shrunk to a minimal length. Exon size is proportional to length, intron height reflects the number of cDNAs supporting each intron, the small numbers show the support of the introns in deep sequencing (with details in mouse-over) . Introns of the same color are identical, of different colors are different. 'Good proteins' are pink, partial or not-good proteins are yellow, uORFs are green. 5' cap or3' poly A flags show completeness of the transcript.
