150-270 1.63e-45

PAZ domain, argonaute_like subfamily. Argonaute is part of the RNA-induced silencing complex (RISC), and is an endonuclease that plays a key role in the RNA interference pathway. The PAZ domain has been named after the proteins Piwi,Argonaut, and Zwille. PAZ is found in two families of proteins that are essential components of RNA-mediated gene-silencing pathways, including RNA interference, the Piwi and Dicer families. PAZ functions as a nucleic acid binding domain, with a strong preference for single-stranded nucleic acids (RNA or DNA) or RNA duplexes with single-stranded 3' overhangs. It has been suggested that the PAZ domain provides a unique mode for the recognition of the two 3'-terminal nucleotides in single-stranded nucleic acids and buries the 3' OH group, and that it might recognize characteristic 3' overhangs in siRNAs within RISC (RNA-induced silencing) and other complexes.

99-149 2.14e-22

Argonaute linker 1 domain; ArgoL1 is a region found in argonaute proteins. It normally co-occurs with pfam02179 and pfam02171. It is a linker region between the N-terminal and the PAZ domains. It contains an alpha-helix packed against a three-stranded antiparallel beta-sheet with two long beta-strands (beta8 and beta9) of the sheet spanning one face of the adjacent N and PAZ domains. L1 together with linker 2, L2, PAZ and ArgoN forms a compact global fold.

N-terminal domain of argonaute; ArgoN is the N-terminal domain of argonaute proteins in eukaryotes. ArgoN is composed of an antiparallel four-stranded beta sheet core that has two alpha helices positioned along one face of the sheet and an extended beta strand towards its N-terminus. The core fold of the N domain most closely resembles the catalytic domain of replication-initiator protein Rep. The N domain is linked to the PAZ domain via linker 1 region, and together these three regions are designated the PAZ-containing lobe of argonaute.

Piwi domain; This domain is found in the protein Piwi and its relatives. The function of this domain is the dsRNA guided hydrolysis of ssRNA. Determination of the crystal structure of Argonaute reveals that PIWI is an RNase H domain, and identifies Argonaute as Slicer, the enzyme that cleaves mRNA in the RNAi RISC complex. In addition, Mg+2 dependence and production of 3'-OH and 5' phosphate products are shared characteriztics of RNaseH and RISC. The PIWI domain core has a tertiary structure belonging to the RNase H family of enzymes. RNase H fold proteins all have a five-stranded mixed beta-sheet surrounded by helices. By analogy to RNase H enzymes which cleave single-stranded RNA guided by the DNA strand in an RNA/DNA hybrid, the PIWI domain can be inferred to cleave single-stranded RNA, for example mRNA, guided by double stranded siRNA.

150-270 1.63e-45

PAZ domain, argonaute_like subfamily. Argonaute is part of the RNA-induced silencing complex (RISC), and is an endonuclease that plays a key role in the RNA interference pathway. The PAZ domain has been named after the proteins Piwi,Argonaut, and Zwille. PAZ is found in two families of proteins that are essential components of RNA-mediated gene-silencing pathways, including RNA interference, the Piwi and Dicer families. PAZ functions as a nucleic acid binding domain, with a strong preference for single-stranded nucleic acids (RNA or DNA) or RNA duplexes with single-stranded 3' overhangs. It has been suggested that the PAZ domain provides a unique mode for the recognition of the two 3'-terminal nucleotides in single-stranded nucleic acids and buries the 3' OH group, and that it might recognize characteristic 3' overhangs in siRNAs within RISC (RNA-induced silencing) and other complexes.

PAZ domain; This domain is named PAZ after the proteins Piwi Argonaut and Zwille. This domain is found in two families of proteins that are involved in post-transcriptional gene silencing. These are the Piwi family and the Dicer family, that includes the Carpel factory protein. The function of the domains is unknown but has been suggested to mediate complex formation between proteins of the Piwi and Dicer families by hetero-dimerization. The three-dimensional structure of this domain has been solved. The PAZ domain is composed of two subdomains. One subdomain is similar to the OB fold, albeit with a different topology. The OB-fold is well known as a single-stranded nucleic acid binding fold. The second subdomain is composed of a beta-hairpin followed by an alpha-helix. The PAZ domains shows low-affinity nucleic acid binding and appears to interact with the 3' ends of single-stranded regions of RNA in the cleft between the two subdomains. PAZ can bind the characteriztic two-base 3' overhangs of siRNAs, indicating that although PAZ may not be a primary nucleic acid binding site in Dicer or RISC, it may contribute to the specific and productive incorporation of siRNAs and miRNAs into the RNAi pathway.

Argonaute linker 1 domain; ArgoL1 is a region found in argonaute proteins. It normally co-occurs with pfam02179 and pfam02171. It is a linker region between the N-terminal and the PAZ domains. It contains an alpha-helix packed against a three-stranded antiparallel beta-sheet with two long beta-strands (beta8 and beta9) of the sheet spanning one face of the adjacent N and PAZ domains. L1 together with linker 2, L2, PAZ and ArgoN forms a compact global fold.

N-terminal domain of argonaute; ArgoN is the N-terminal domain of argonaute proteins in eukaryotes. ArgoN is composed of an antiparallel four-stranded beta sheet core that has two alpha helices positioned along one face of the sheet and an extended beta strand towards its N-terminus. The core fold of the N domain most closely resembles the catalytic domain of replication-initiator protein Rep. The N domain is linked to the PAZ domain via linker 1 region, and together these three regions are designated the PAZ-containing lobe of argonaute.

Piwi domain; This domain is found in the protein Piwi and its relatives. The function of this domain is the dsRNA guided hydrolysis of ssRNA. Determination of the crystal structure of Argonaute reveals that PIWI is an RNase H domain, and identifies Argonaute as Slicer, the enzyme that cleaves mRNA in the RNAi RISC complex. In addition, Mg+2 dependence and production of 3'-OH and 5' phosphate products are shared characteriztics of RNaseH and RISC. The PIWI domain core has a tertiary structure belonging to the RNase H family of enzymes. RNase H fold proteins all have a five-stranded mixed beta-sheet surrounded by helices. By analogy to RNase H enzymes which cleave single-stranded RNA guided by the DNA strand in an RNA/DNA hybrid, the PIWI domain can be inferred to cleave single-stranded RNA, for example mRNA, guided by double stranded siRNA.

Piwi-like: PIWI domain. Domain found in proteins involved in RNA silencing. RNA silencing refers to a group of related gene-silencing mechanisms mediated by short RNA molecules, including siRNAs, miRNAs, and heterochromatin-related guide RNAs. The central component of the RNA-induced silencing complex (RISC) and related complexes is Argonaute. The PIWI domain is the C-terminal portion of Argonaute and consists of two subdomains, one of which provides the 5' anchoring of the guide RNA and the other, the catalytic site for slicing. This domain is also found in closely related proteins, including the Piwi subfamily, where it is believed to perform a crucial role in germline cells, via a similar mechanism.

150-270 1.63e-45

PAZ domain, argonaute_like subfamily. Argonaute is part of the RNA-induced silencing complex (RISC), and is an endonuclease that plays a key role in the RNA interference pathway. The PAZ domain has been named after the proteins Piwi,Argonaut, and Zwille. PAZ is found in two families of proteins that are essential components of RNA-mediated gene-silencing pathways, including RNA interference, the Piwi and Dicer families. PAZ functions as a nucleic acid binding domain, with a strong preference for single-stranded nucleic acids (RNA or DNA) or RNA duplexes with single-stranded 3' overhangs. It has been suggested that the PAZ domain provides a unique mode for the recognition of the two 3'-terminal nucleotides in single-stranded nucleic acids and buries the 3' OH group, and that it might recognize characteristic 3' overhangs in siRNAs within RISC (RNA-induced silencing) and other complexes.

352-434 6.21e-44

Mid domain of argonaute; The ArgoMid domain is found to be part of the Piwi-lobe of the argonaute proteins. It is composed of a parallel four-stranded beta-sheet core surrounded by four alpha-helices and two additional short alpha-helices. It most closely resembles the amino terminal tryptic core of the E.coli lactose repressor. There is an extensive interface between the Mid and the Piwi domains. The conserved C-terminal half or the Mid has extensive interactions with Piwi, with a deep basic pocket on the surface of the `Mid adjacent to the interface with Piwi. The Mid carries a binding pocket for the 5' phosphate overhang of the guide strand of DNA. The N, Mid, and Piwi domains form a base upon which the PAZ domain sits, resembling a duck. The 5' phosphate and the U1 base are held in place by a conserved network of interactions from protein residues of the Mid and Piwi domains in order to place the guide uniquely in the proper position observed in all Argonaute-RNA complexes.

PAZ domain; This domain is named PAZ after the proteins Piwi Argonaut and Zwille. This domain is found in two families of proteins that are involved in post-transcriptional gene silencing. These are the Piwi family and the Dicer family, that includes the Carpel factory protein. The function of the domains is unknown but has been suggested to mediate complex formation between proteins of the Piwi and Dicer families by hetero-dimerization. The three-dimensional structure of this domain has been solved. The PAZ domain is composed of two subdomains. One subdomain is similar to the OB fold, albeit with a different topology. The OB-fold is well known as a single-stranded nucleic acid binding fold. The second subdomain is composed of a beta-hairpin followed by an alpha-helix. The PAZ domains shows low-affinity nucleic acid binding and appears to interact with the 3' ends of single-stranded regions of RNA in the cleft between the two subdomains. PAZ can bind the characteriztic two-base 3' overhangs of siRNAs, indicating that although PAZ may not be a primary nucleic acid binding site in Dicer or RISC, it may contribute to the specific and productive incorporation of siRNAs and miRNAs into the RNAi pathway.

Argonaute linker 1 domain; ArgoL1 is a region found in argonaute proteins. It normally co-occurs with pfam02179 and pfam02171. It is a linker region between the N-terminal and the PAZ domains. It contains an alpha-helix packed against a three-stranded antiparallel beta-sheet with two long beta-strands (beta8 and beta9) of the sheet spanning one face of the adjacent N and PAZ domains. L1 together with linker 2, L2, PAZ and ArgoN forms a compact global fold.

Argonaute linker 2 domain; ArgoL2 is the second linker domain in eukaryotic argonaute proteins. It starts with two alpha-helices aligned orthogonally to each other followed by a beta-strand involved in linking the two lobes, the PAZ lobe and the Piwi lobe of argonaute to each other. Linker 2 together with the N, PAZ and L1 domains form a compact global fold. Numerous residues from Piwi, L1 and L2 linkers direct the path of the phosphate backbone of nucleotides 7-9, thus allowing DNA-slicing.

N-terminal domain of argonaute; ArgoN is the N-terminal domain of argonaute proteins in eukaryotes. ArgoN is composed of an antiparallel four-stranded beta sheet core that has two alpha helices positioned along one face of the sheet and an extended beta strand towards its N-terminus. The core fold of the N domain most closely resembles the catalytic domain of replication-initiator protein Rep. The N domain is linked to the PAZ domain via linker 1 region, and together these three regions are designated the PAZ-containing lobe of argonaute.
