A [auth B] | PF17953 | CRISPR Csm4 C-terminal domain (Csm4_C) | CRISPR Csm4 C-terminal domain | Clustered, regularly interspaced, short palindromic repeat (CRISPR) loci play a pivotal role in the prokaryotic host defense system against invading genetic materials. The CRISPR loci are transcribed to produce CRISPR RNAs (crRNAs), which form interf ... | Domain |

L [auth A] | PF18211 | Csm1 subunit domain B (Csm1_B) | Csm1 subunit domain B | This domain is found in the Csm1 subunit of the Csm complex found in Thermococcus onnurineus. Csm is a type III-A CRISPR-Cas system, which is an RNA-guided immune defense mechanism that detects and destroys foreign DNA or RNA. This domain is known as ... | Domain |
L [auth A] | PF20824 | CRISPR RNA silencing complex Cmr2 subunit, second helical domain (Cmr2_hel_dom2) | CRISPR RNA silencing complex Cmr2 subunit, second helical domain | The prokaryotic CRISPR RNA-Cas protein (Cmr) complex provides protection against mobile genetic elements by cleaving foreign RNA. Its largest subunit is Cmr2. This protein shows a N-terminal HD (histidine-aspartate) domain, two RRM domains resembling ... | Domain |
