Cyclic di-nucleotide phosphodiesterase (CdnP, also known as Rv2837c) is a soluble, stand-alone phosphodiesterase in regulating cyclic dinucleotide signaling during intracellular infections of M. tuberculosis{36095}. Studies have found that CdnP is capable of hydrolyzing cyclic di-adenosine monophosphate (c-di-AMP; Item No. 17753) into two AMPs as a strategy to avoid activation of the innate immune response of the host. M. tuberculosis infection leads to cytosolic release of c-di-AMP, which is recognized by stimulator of interferon genes (STING) and subsequently triggers type I interferon response. Other studies have shown that deletion or inhibition of CdnP attenuates the M. tuberculosis virulence both in vitro and in vivo.
