CRISPR is a term for Clustered, Regularly Interspaced Short Palindromic Repeats. A number of protein families appear only in association with these repeats and are designated Cas (CRISPR-Associated) proteins. This entry represents a minor family of Cas proteins found in various species of Sulfolobus and Pyrococcus (all archaeal). It is found with two different CRISPR loci in Sulfolobus solfataricus.
