CommentCRISPR is a term for Clustered, Regularly Interspaced Short Palidromic Repeats. A number of protein families appear only in association with these repeats and are designated Cas (CRISPR-Associated) proteins. This (revised) HMM describes a conserved region from an otherwise highly divergent protein found in the Tneap subtype of CRISPR/Cas regions. This Cys-rich region features two motifs of CXXC.
