The lobster shaw gene: cloning, sequence analysis and comparison to fly shaw.

We cloned and sequenced the cDNA for the shaw gene, encoding a voltage-dependent potassium (K+) channel, from the spiny lobster, Panulirus interruptus. The deduced amino acid sequence has a high degree of homology to the Drosophila melanogaster Shaw protein. In addition, lobster Shaw has several putative sites for post-translational modifications.
