CRISPR-associated protein 1 (cas1) is one of the two universally conserved proteins found in the CRISPR prokaryotic immune defense system. Cas1 is a metal-dependent DNA-specific endonuclease that produces double-stranded DNA fragments.[1] Cas1 forms a stable complex with the other universally conserved CRISPR-associated protein, cas2, which is essential to spacer acquisition for CRISPR systems.[2]
