AIM To analyze the alternatively spliced variant of Stam2 mRNA and determine its distribution in mouse tissues. METHODS We identified a novel alternatively spliced exon by cloning and sequencing of Stam2 cDNA obtained from tissue samples of 3-5 months old male C57Bl/6NCrl mice. The sequence of the alternatively spliced exon was analyzed by bioinformatic tools. The tissue distribution of diffe...

MOTIVATION While the mechanism for regulating alternative splicing is poorly understood, secondary structure has been shown to be integral to this process. Due to their propensity for forming complementary hairpin loops and their elevated mutation rates, tandem repeated sequences have the potential to influence splicing regulation. RESULTS An analysis of human intronic sequences reveals a str...

Dystrophin transcripts were shown to be alternatively spliced in a pattern characteristic of both tissue type and developmental stage. Multiple novel spliced forms of dystrophin mRNA were identified in murine brain tissue, skeletal and cardiac muscle, diaphragm, and human cardiac Purkinje fibers. The transcript diversity was greatest in adult, non-skeletal muscle tissues. Sequence analysis reve...
