Expression: According to AceView, this gene is
expressed at low level, only 6.5% of the average gene in this release. The
sequence of this gene is defined by
8 GenBank accessions, some from 2 pooled high-grade transitional celltumors (seen once), genitourinary tract (once), normal prostate (once), pooled human melanocyte, fetal heart, andpregnant uterus (once), prostate (once), serous papillary carcinoma, high grade, 2pooled tumors (once), ureter (once), uterus (once).
Alternative mRNA variants and regulation: The gene contains
8 distinct gt-ag introns. Transcription produces
2 alternatively spliced mRNAs. The mRNAs appear to differ by presence or absence of a
cassette exon. 259 bp of this gene
are antisense to spliced gene swersoy, raising the possibility of regulated alternate expression.
Function: There are
13 articles specifically referring to this gene in PubMed. Functionally, the gene has been tested for association to
diseases (Carcinoma, Transitional Cell; Urinary Bladder Neoplasms) and proposed to participate in a
process (protein oligomerization). Proteins are expected to have molecular
functions (monosaccharide binding, protein homodimerization activity) and to
localize in various compartments (endoplasmic reticulum membrane, integral to membrane, plasma membrane). Putative
protein interactors have been described (UPK1A, UPK2).
Protein coding potential: The 2 spliced mRNAs putatively encode
good proteins, altogether
2 different isoforms (2 complete), containing Tetraspanin family
domain [Pfam], some transmembrane domains
[Psort2].

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.

Mouse over the ending of each transcript gives tissues from which the supporting cDNAs were extracted. Details on tissue of origin for each intron and exon is available from the
intron and exons table.
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. Proteins supported by a single continuous cDNA sequence 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
