This domain is found N-terminal in CRISPR-associated protein Csa3 and related proteins. Csa3 consists of two domains [1-3]. The N-terminal domain is a unique variation on the dinucleotide binding domain and it is responsible for dimer formation. In addition, it utilizes two conserved sequence motifs T(h)GF(N/D)E(x)4R and L(x)2G(h)R to form a 2-fold symmetric pocket on the dimer axis. This pocket is likely to represent a regulatory ligand-binding site.	Domain
