In line with this, detection of alternatively spliced RNAs by RT-PCR, which has been frequently used, does not appear to be an appropriate technique providing sufficient evidence for alternative splicing.
The finding that the F3744A mutation increased levels of cytoplasmic Tra1 is consistent with this model, or alternatively for roles of the FATC domain and Tti2 in protein trafficking.
Joint optimization of this criterion, alternatively with respect to f(with fixed τ) f ^ = arg min f { J ( f, τ ) } = arg min f 1 2 v ε g - H f 2 + ∑ j 1 2 τ j f j 2 (60).
which is summarized as follows: Joint optimization of this criterion, alternatively with respect to f(with fixed τ) f ^ = arg min f { J ( f, τ ) } = arg min f 1 2 v ε ∥ g - H f ∥ 2 + ∑ j 1 2 τ j f j 2 (38).
Again, in this case also, the optimization of this criterion, alternatively with respect to f and z results in the following iterative algorithm: f ^ = [ H ′ H + v ε D ( z ) ] - 1 H ′ g z ^ j = ϕ ( f j ) = 1, if f j 2 ^ ≥ ( v 1 - v 0 ) ln 1 - λ λ 0, if f j 2 ^ < ( v 1 - v 0 ) ln 1 - λ λ D ( z ^ ) = diag v z j ^, j = 1,.., n (71).
Example alignments of alternatively spliced ESTs are shown in additional file 4. With this method 529 potential alternatively spliced messages were constructed comprising 9%% of all clusters.
This possibility was tested by searching for domains that were significantly enriched with alternatively spliced rather than with constitutively spliced introns.
Comparison of ESTs with genomic sequence revealed 1782 genes with alternatively spliced transcripts (Wormbase release WS130), which accounts for about 9% of all C. elegans genes.
The resultant hydrogel was aged at room temperature, following with washing alternatively with distilled water and absolute ethanol.
For genes with multiple alternatively spliced transcripts, the longest transcript was kept.
