Figure 4. Splice variant of TNNT1.A: The genomic structure of TNNT1 is shown. B: Detailed illustration of the genomic region from exon 3 to exon 5 is given. C: The mRNA sequence of exon 4, their flanking sequences, and the corresponding translated amino acids are pictured. Translated exons are shown as solid boxes. Untranslated regions are shown as gray bars. The exons are numbered by Arabic numerals. The length in base pairs is given for each sequence. Exon 4 is marked in red. The corresponding mRNA sequence and the translation product of exon 4 are printed in italics.
