DEXXQ-box helicase domain of SETX; The RNA/DNA helicase senataxin (SETX) plays a role in transcription, neurogenesis, and antiviral response. SEXT is an R-loop-associated protein that is thought to function as an RNA/DNA helicase. R-loops consist of RNA/DNA hybrids, formed during transcription when nascent RNA hybridizes to the DNA template strand, displacing the non-template DNA strand. Mutations in SETX are linked to two neurodegenerative disorders: ataxia with oculomotor apraxia type 2 (AOA2) and amyotrophic lateral sclerosis type 4 (ALS4). S. cerevisiae homolog splicing endonuclease 1 (Sen1) is an exclusively nuclear protein, important for nucleolar organization. S. cerevisiae Sen1 and its ortholog, the Schizosaccharomyces pombe Sen1, share conserved domains and belong to the family I class of helicases. Both proteins translocate 5' to 3' and unwind both DNA and RNA duplexes and also RNA/DNA hybrids in vitro. SETX is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

DEXXQ-box helicase domain of UPF1; UPF1 (also called RNA Helicase And ATPase, Regulator Of Nonsense Transcripts, or ATP-Dependent Helicase RENT1) is an RNA-dependent helicase and ATPase required for nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. It is recruited to mRNAs upon translation termination and undergoes a cycle of phosphorylation and dephosphorylation; its phosphorylation appears to be a key step in NMD. It is recruited by release factors to stalled ribosomes together with the SMG1C protein kinase complex to form the transient SURF (SMG1-UPF1-eRF1-eRF3) complex. In EJC-dependent NMD, the SURF complex associates with the exon junction complex (EJC) located downstream from the termination codon through UPF2 and allows the formation of an UPF1-UPF2-UPF3 surveillance complex which is believed to activate NMD. Diseases associated with UPF1 include juvenile amyotrophic lateral sclerosis and epidermolysis bullosa, junctional, non-Herlitz type. UPF1 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

helicase domain of gammacoronavirus non-structural protein 13; This model represents the helicase domain of non-structural protein 13 (Nsp13) from gammacoronavirus, including Avian infectious bronchitis virus. Helicases catalyze NTP-dependent unwinding of nucleic acid duplexes into single strands and are classified based on the arrangement of conserved motifs into six superfamilies. Coronavirus (CoV) Nsp13 is a member of the helicase superfamily 1 (SF1); SF1 and SF2 helicases do not form toroidal structures, while SF3-6 helicases do. Nsp13 is a component of the viral RNA synthesis replication and transcription complex (RTC). It is a multidomain protein containing a Cys/His rich zinc-binding domain (CH/ZBD), a stalk domain, a 1B domain involved in nucleic acid substrate binding, and a SF1 helicase core.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
