Caenorhabditis elegans essential gene gop-3, encoding i-51 protein, Gro-1 OPeron gene.
TABLE OF CONTENTS / OPEN CLOSE ALL PARAGRAPHS
SUMMARY
Summary
[Wormbase] gop-3 encodes an ortholog of the mammalian CGI-51 (comparative gene identification-51) proteins that display a high degree of similarity to the Haemophilus influenza D15 protective surface antigen; loss of gop-3 activity via large-scale RNAi screens indicates that GOP-3 is required for embryonic and larval development, as well as for normal postembryonic growth rates
.
Wormbase predicts one model, but Caenorhabditis elegans cDNA sequences in GenBank, 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 summary
Expression: According to AceView, this gene is
expressed at high level, 3.0 times the average gene in this release, mostly from L1 larvae to adult [Kohara cDNAs]. The
sequence of this gene is defined by
39 cDNA clones, some from whole animal (seen 2 times). We annotate
structural defects or features in one cDNA clone.
Alternative mRNA variants and regulation: The gene contains
8 distinct gt-ag introns. Transcription produces
3 alternatively spliced mRNAs. There are 2 validated
alternative polyadenylation sites (see the
diagram). The mRNAs appear to differ by by overlapping exons with different boundaries, splicing versus retention of one intron.
Protein coding potential: The 3 spliced mRNAs putatively encode
good proteins, altogether
3 different isoforms (3 complete, 1 COOH complete), some containing Bacterial surface antigen (D15)
domain [Pfam].
Function: There are
2 articles specifically referring to this gene in PubMed. In addition we point
below to one abstract. This essential gene is associated to a
phenotype (Embryonic Lethal, Gro-1 OPeron gene, SLow growth). Proteins are expected to
localize in various compartments (cytoplasm, outer membrane).

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 cDNA clones supporting each intron. Superimposed introns of the same color are identical, of different colors are different.
Mouse over the ending of each transcript gives tissues from which the supporting cDNAs were extracted. Click on any transcript to open the specific mRNA page, to see the exact cDNA clone support and eventual SNPs and to get details on tissues, sequences, mRNA and protein annotations. Details on tissue of origin for each intron and exon is available from the
intron and exons table. Good predicted proteins are in pink, yellow proteins may be partial or unconvincing, green are uORFs. Proteins supported by a single continuous GenBank accession lead to underlining the name/ending of the variant. Names not underlined result from cDNA concatenation in the coding region and should be experimentally checked.

Introns are depicted by broken lines; the height of the top of each intron reflects the relative number of clones supporting this intron.
]^[ A pink broken line denotes an intron with standard boundaries (gt-ag or gc-ag) that is exactly supported (i.e. a cDNA sequence exactly matches the genome over 16 bp, 8 on both sides of the intron).
] ^ ] A blue broken line denotes non-standard introns, exactly supported, but with non-standard at-ac or any other boundaries.
]-[ Pink and
] - ] blue straight lines represent 'fuzzy' introns of the standard and non-standard types respectively, those introns do not follow the 16 bp rule. Black straight lines ]-[denote gaps in the alignments.
Exons: Wide filled pink areas represent putative protein coding regions, narrow empty pink boxes represent the 5'UTR (on the left) and 3' UTR (on the right). Flags identify validated endings: cap site on the 5' side, polyadenylation site on the 3' side. Filled flags correspond to frequent events while empty flags have lesser supporting cDNAs (yet all are validated); at the 3' side, black flags are associated to the main AATAAA signal,
blue flags to any single letter variant of the main . More explanations are given in the
