Outline of Final Research Achievements

In this research, I tried to identify a kinase that changes the phosphorylation state of serine 315 (S315) of ceramide transport protein (CERT) when its expression level is suppressed by transfection of siRNA library. As a result, I showed that suppressed expression of a certain stress-responsive kinase decreased the phosphorylation state of CERT S315. From the information about the kinase, I speculated that an environmental factor might be involved in phospho-regulation of CERT and experimentally showed that the factor critically up-regulated the phosphorylation state of CERT S315.
