Figure 3. Amino acid alignments of the deduced OST beta sequences from multiple species.
Reference sequences for the human, mouse, dog, horse, chicken, zebrafish, and skate OST beta proteins were obtained from the NCBI database and were aligned using the MUSCLE program (multiple sequence comparison by log-expectation; http://www.ebi.ac.uk/Tools/muscle/index.html). The predicted TM domain is boxed. “*” denotes the amino acids that are conserved among the seven species; “:” denotes that conserved substitutions are observed; “.” denotes that semi-conserved substitutions are observed.
