The cyclic pyrimidine nucleotide cCMP has been suggested to serve as second messenger. However, phosphodiesterases studied so far do not hydrolyze cCMP. Therefore, we searched for alternative cCMP inactivation mechanisms. cCMP is a substrate for multidrug resistance protein 5, indicating that export from the cytosol into the extracellular space is an important inactivation mechanism for cCMP.
