"Being responsible for my own research project has been a great incentive to step out of my scientific comfort zone and explore areas less familiar to me such as Molecular Biology. These bacteria were transformed to produce a plasmid containing a synthetic piece of double stranded DNA I designed." - Lisi Krainer

Research Interests

  • Not currently doing wet lab research. Expression of myofibrillar proteins at the early stages of heart development.


Striated muscle tropomyosin is classically described as consisting of 10 exons, 1a, 2b, 3, 4, 5, 6b, 7, 8, and 9a/b, in both skeletal and cardiac muscle. Experiments in our laboratory have demonstrated expression of a naturally occurring chimeric isoform of tropomyosin that has both smooth and striated muscle exons. The chimeric isoform has a replacement of exon 2a for 2b that is commonly found in striated isoforms. GFP constructs were used to demonstrate translation and incorporation into organized myofibrils. Antisense oligonucleotide transfection decreased the expression of this isoform and disrupted organization and function.
