Zinc-finger double-stranded RNA-binding; This domain family is found in archaea and eukaryotes, and is approximately 30 amino acids in length. The mammalian members of this group occur multiple times along the protein, joined by flexible linkers, and are referred to as JAZ - dsRNA-binding ZF protein - zinc-fingers. The JAZ proteins are expressed in all tissues tested and localize in the nucleus, particularly the nucleolus. JAZ preferentially binds to double-stranded (ds) RNA or RNA/DNA hybrids rather than DNA. In addition to binding double-stranded RNA, these zinc-fingers are required for nucleolar localization.

GIY-YIG nuclease domain superfamily; The GIY-YIG nuclease domain superfamily includes a large and diverse group of proteins involved in many cellular processes, such as class I homing GIY-YIG family endonucleases, prokaryotic nucleotide excision repair proteins UvrC and Cho, type II restriction enzymes, the endonuclease/reverse transcriptase of eukaryotic retrotransposable elements, and a family of eukaryotic enzymes that repair stalled replication forks. All of these members contain a conserved GIY-YIG nuclease domain that may serve as a scaffold for the coordination of a divalent metal ion required for catalysis of the phosphodiester bond cleavage. By combining with different specificity, targeting, or other domains, the GIY-YIG nucleases may perform different functions.

Catalytic GIY-YIG endonuclease domain of penelope-like elements and similar proteins; This model corresponds to the EN domain of PLEs that contains catalytic module of the GIY-YIG endonucleases of group I bacterial/organellar introns, as well as bacterial UvrC DNA repair proteins. It can cleave DNA with low nucleotide sequence specificity. However, the PLEs EN domain is distinct from other GIY-YIG endonucleases by the presence of a well-conserved CCHH motif (CX(2-7)CX(33-39)HX(3-5)H, X can be any residue). The role of the CCHH motif has not yet been identified. Penelope-like elements (PLEs) represent a novel class of eukaryotic retroelements, which do not belong to either long terminal repeat (LTR) retrotransposons or non-LTR retrotransposons (often called LINEs), but instead form a sister clade to telomerase reverse transcriptases (TERTs), highly specialized non-mobile reverse transcriptases (RTs) which are responsible for the addition of telomeric repeats to the ends of eukaryotic chromosomes. The single open reading frame (ORF) encoded by PLE consists of two principal domains, RT domain and endonuclease (EN) domain, jointed by a linker region of variable length. Both of these two domains are functionally active.

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity.
