The promoter from which expression is initiated is located within the leader region and generates a single RNA transcript called the pre-crRNA.  In the case of E. coli, the CRISPR is associated with eight cas genes, the products of five of which form a complex called Cascade.

The promoter or enhancer segments of all genes regulated by PKA contain a cis-acting DNA sequence, the cAMP-response element (CRE), which

contains the highly conserved nucleotide sequence,

5'-TGACGTCA-3'.
