Expression of Tropomyosin 1 Gene Isoforms in Human Breast Cancer Cell Lines

Figure 1

Cartoon showing the various exons (boxes) and introns (lines) of the human tropomyosin 1 gene and its various RNA isoforms identified to date. TPM1 are the newly described isoforms herein. The exons identified by the antibodies TM311, TM1E2, and CH1 are identified. Those exons that are translated as peptides are indicated by solid or hatched, and so forth, markings, while those that are not are left blank. The translation profiles for TPM1 are assumed.
