Alternative splicing in the human rhoa protein. a. Amino acid sequence of the protein. The splicing region was identified based on the homology with the human cDNA sequence associated with large cell carcinoma (GenBank accession number BQ231766) as well as several other cDNAs. b. Graphical representation of the spliced and interacting regions. c. Ribbon representation of the three-dimensional structure (PDB code 1CXZ, chain a). Colouring as in Figure 2.
