About H-DBAS

  • H-DBAS is a unique database of alternative splicing (AS) based on H-InvDB. The features of H-DBAS is as follows;
    1. Representative AS variants (RASVs) were identified from 8 data sets consist of 6 mammalian model organisms (human, mouse, rat, chimpanzee, macaque and dog). The contents of data sets and the corresponding species are as follows;
      • Full-length cDNA data set: H-Invitational in H-InvDB (Human), FANTOM3 + MGC (Mouse)
      • mRNA data set: H-InvDB (Human and Mouse)
      • RNA data set: H-InvDB + RefSeq + Ensembl (Rat, Chimpanzee, Macaque and Dog)
    2. Equally-spliced variants (ESVs) were identified from RASVs between human and mouse, rat, chimpanzee, macaque and dog by using comparative genomics. The combinations of compared data sets are as follows;
      • Human (Full-length cDNA) - Mouse (Full-length cDNA)
      • Human (mRNA) - Mouse (mRNA)
      • Human (mRNA) - Rat (RNA)
      • Human (mRNA) - Chimpanzee (RNA)
      • Human (mRNA) - Macaque (RNA)
      • Human (mRNA) - Dog (RNA)
    3. Splice sites and splice motifs affecting SNPs can be observed in human.
    4. RASVs affecting protein functions (protein motif, GO, subcellular localization signal and transmembrane domain) can be observed in human.
    5. AS junctions expressed in specified cellular fractions (cytoplasm, nuclear and polysome) of human cell were detected by using RNA-Seq tags. The translation validation of the variants having AS junctions were analyzed by compared with RefSeq junctions. The results are shown from RNA-Seq analysis page.
