In a very recent report, Fujita's laboratory also demonstrated that the inhibitory phenotype of S183I RIG-I was neither due to a failure of ubiquitination [20]; a post-translational process essential for RIG-I activity [21].
Even though total drilling in the Gulf will be down 20% year-over-year, there will be an equal decrease in the number of rigs, thus activity will remain tight.
