They observed a complex tissue-specific pattern of multiple spliced forms of BRCA1, and suggested that splicing may play a role in the regulation of BRCA1 function.
We used the longest transcripts for genes with multiple spliced forms.
The second limitation affects all gene array studies and derives from the fact that one gene can encode multiple spliced forms of transcripts, and further, the translated proteins undergo various post-translation modifications.
In addition, the P48L, Q156H, K287I, R388W, and R425H missense mutations result in expression of mutant AMPD-1 proteins with negligible enzymatic activity [ 274, 276, 277], while a deletion mutation (IVS2 del CTTT) leads to expression of multiple inactive spliced forms of the protein [ 277].
The DYRK1A mRNA has multiple splice forms.
Thus, as in rodents and primates, prominin-1 from non-mammalian vertebrate animal models has the same propensity to appear in various alternatively spliced forms being suggestive of multiple — yet unidentified — interacting partners and/or specific functions.
Most genes use alternative splicing to generate multiple spliced transcripts.
Of these 206 genes, 50 are entirely deleted (51 spliced forms deleted), 80 are truncated (84 spliced forms disrupted), 75 genes have preserved ORF (224 spliced forms), and 1 gene (F14D2.4) has one spliced form with its ORF preserved (F14D2.4b) whereas the other spliced form has its ORF disrupted (F14D2.4a).
Altogether, we envisage this could generate spurious splicing events leading to the appearance of multiple spliced transcripts that we have shown to exist in Helitron-captured genes.
We also assessed the impact of SNVs on individual spliced forms because same SNVs can have differential impact on different spliced forms of a same gene.
The RNase activity mediates an unconventional splicing of the mRNA encoding a key transcription factor, HAC1 (yeast), XBP1 (animals), AtbZIP60 (Arabidopsis) or OsbZIP50 (rice); the spliced forms of these mRNAs are translated as active forms4,5,6,7,8.
