According to AceView, this gene is well expressed
, 0.8 times the average gene in this release. The sequence
of this gene is defined by 92 GenBank accessions
from 80 cDNA clones, some from brain (seen 13 times), eye (5), lung (5), colon (4), glioblastoma (pooled) (3), lymph (3), medulla (3) and 57 other tissues
. We annotate structural defects or features
in 7 cDNA clones.
There are 3 articles
specifically referring to this gene in PubMed. Functionally, the gene has been proposed to participate in a process
(protein folding). Proteins are expected to have molecular functions
(heat shock protein binding, unfolded protein binding) and to localize
in various compartments (membrane, mitochondrion). A putative protein interactor
has been described (EXOSC6). This gene contains DnaJ domain [Pfam]
, some transmembrane domains [Psort2]

You may also examine the strand-specific genome coverage plots on the experimental AceView/Magic hub at UCSC
, by tissue or by species. Tracks may be slow to load
; please reload if some tracks come up yellow-greenish, and thanks to UCSC for the great work!.
About UCSC tracks: you may enjoy the plots for the summed coverage over all primates' libraries (top track), summarizing 3 terabases of stranded RNA-seq. Fragments mapping on the + strand of the genome (from genes on the + strand) are red (or dark), on minus strand blue (or light) and antisense transcribed areas are black or overlaid. The vertical scale for each track is self-adapting. Homozygous SNPs tracks are also presented.
About mapping: Primates body map RNA-seq data were stringently mapped to the human genome using the NCBI Magic pipeline. Normalized results are shown as significant FPKM (sFPKM), which includes corrections on F, K and M, computed from parameters measured directly in each RNA-seq experiment, to render the expression measures more significant and more robust to experimental biases. Only fragments with both reads mapped uniquely and over at least 80+80 bases ending with 8 exact bases on each side of each read, and facing each other in a single site or gene, are included in the computation of the sFPKM/index, in the coverage plots, and in the determination of homozygous SNPs (minimum coverage 10, minimum allele frequency 95%). But be aware that genes whose sequence evolved to become too distant from Human cannot be measured well, this bias can be appreciated in the per-species coverage plots at UCSC.
About libraries: For non-human primates, total RNA libraries used TruSeq, ribozero and the stranded UDG protocol. The human 2010 libraries used the polyA selected non-stranded protocol, with short reads (50, 75 or 50+50 bases); furthermore the insert lengths are larger in human than in the non-human primates (average insert size 187 bp in non-human primates versus 232 bp in human). These protocol differences may impact expression measures for the non polyadenylated genes (or genes with shorter or occasional polyA tails), for the pseudogenes or close gene families (specificity is reduced in humans due to shorter reads), and for the very short genes.

Annotated mRNA diagrams
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.
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.
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 gene help file
