Splice junction

Gene annotations, such as those in GENCODE, are derived primarily from alignments of spliced cDNA sequences and protein sequences. The impact of RNA-seq data on annotation has been confined to major projects like ENCODE and Illumina Body Map 2.0.

Transcriptome assemblers aim to reconstruct full-length transcripts from RNA-seq data. We present TransComb, a genome-guided assembler developed based on a junction graph, weighted by a bin-packing strategy and pairedend information. A newly designed extension method based on weighted junction graphs can accurately extract paths representing expressed transcripts, whether they have low or high expression levels.

Alternative splicing, which generates multiple mRNA isoforms from single genes, is crucial for the regulation of eukaryotic gene expression. The flux through competing splicing pathways cannot be determined by traditional RNA-Seq, however, because different mRNA isoforms can have widely differing decay rates.

TopHat is a popular spliced junction mapper for RNA sequencing data, and writes files in the BAM format – the binary version of the Sequence Alignment/Map (SAM) format. BAM is the standard exchange format for aligned sequencing reads, thus correct format implementation is paramount for software interoperability and correct analysis.

We used a combined computer and biochemical approach to characterize human pyridoxine 5¢-phosphate oxidase (PNPO).The human PNPOgene is composed of seven exons and six introns, and spans approximately 8 kb.All exon/intron junctions contain the gt/ag consensus splicing site.The absence of TATA-like sequences, the presence of Sp1-binding sites and more importantly, the presence of CpG islands in the regulatory region of thePNPOgene are characteristic features of housekeeping genes.

Protein phosphorylation ensures the accurate and controlled expression of the genome, for instance by regulating the activities of pre-mRNA splicing factors. Here we report that splicing factor 1 (SF1), which is involved in an early step of intronic sequence recognition, is highly phosphorylated in mam-malian cells on two serines within an SPSP motif at the junction between its U2AF 65 and RNA binding domains.

The tight junction protein occludin participates in cell adhesion and migra-tion and has been shown to possess antitumorigenic properties; however, the exact mechanism underlying these effects is poorly understood. In liver cell lines, we identified an occludin splice variant deleted in exon 9 (Occ DE9 ).
