Common Namecyclic tetraadenylate
DescriptionCyclic tetraadenylate is a cyclic nucleotide that belongs to the class of adenine-based metabolites. Its chemical structure features a cyclic arrangement of four adenosine monophosphate (AMP) units, which are linked by phosphodiester bonds, creating a unique cyclic tetramer. This compound plays a significant role in various biochemical pathways, particularly in the activation of CRISPR-associated nucleases. For instance, cyclic tetraadenylate binding induces dimerization of protein dimers, which is essential for the activation of a CRISPR-associated PIN nuclease (PMID:40794864 ). Additionally, biochemical characterization of CaPN has shown that the CARF domain specifically senses cyclic tetraadenylate, leading to the activation of the PIN domain for effective RNA cleavage (PMID:40794864 ). Moreover, the Csx1 homolog, SyCsx1, functions as a cyclic tetraadenylate-dependent RNase, exhibiting strict specificity for cytosine nucleotides (PMID:36419420 ). These interactions highlight the importance of cyclic tetraadenylate in RNA metabolism and the regulatory mechanisms of CRISPR systems, underscoring its relevance in both molecular biology and biochemistry.
