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.

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.

It is involved in Okazaki fragment processing by cleaving long flaps that escape FEN1: flaps that are longer than 27 nucleotides are coated by replication protein A complex (RPA), leading to recruit DNA2 which cleaves the flap until it is too short to bind RPA and becomes a substrate for FEN1. It is also involved in 5-end resection of DNA during double-strand break (DSB) repair; it is recruited by BLM and mediates the cleavage of 5-ssDNA, while the 3-ssDNA cleavage is prevented by the presence of RPA.

EEXXE-box helicase domain of NFX1; Human NFX1 protein was identified as a protein that represses class II MHC (major histocompatibility complex) gene expression. NFX1 binds a conserved cis-acting element, termed the X-box, in promoters of human class II MHC genes. The Cys-rich region contains several NFX1-type zinc finger domains. Frequently, a R3H domain is present in the C-terminus, and a RING finger domain and a PAM2 motif are present in the N-terminus. The lack of R3H and PAM2 motifs in the plant proteins indicates functional differences. Plant NFX1-like proteins are proposed to modulate growth and survival by coordinating reactive oxygen species, salicylic acid, further biotic stress and abscisic acid responses. A common feature of all members may be E3 ubiquitin ligase, due to the presence of a RING finger domain, as well as DNA binding. NFX1 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.

C-terminal helicase domain of superfamily 1 DEAD/H-box helicases; Superfamily (SF)1 family members include UvrD/Rep, Pif1-like, and Upf-1-like proteins. Similar to SF2 helicases, they do not form toroidal, predominantly hexameric structures like SF3-6. SF1 helicases are a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Their helicase core is surrounded by C- and N-terminal domains with specific functions such as nucleases, RNA or DNA binding domains, or domains engaged in protein-protein interactions. The core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

Cys/His rich zinc-binding domain (CH/ZBD) of eukaryotic UPF1 helicase, nidovirus SF1 helicases including coronavirus Nsp13 and arterivirus Nsp10, and related proteins; 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. Members of this family belong to helicase superfamily 1 (SF1) and include nidoviral helicases such as Severe Acute Respiratory Syndrome coronavirus (SARS) non-structural protein 13 (SARS-Nsp13) and equine arteritis virus (EAV) Nsp10, as well as eukaryotic UPF1 helicase. The CH/ZBD has 3 zinc-finger (ZnF1-3) motifs. UPF1 participates in nonsense-mediated mRNA decay (NMD), a pathway which degrades transcripts with premature termination codons. The CH/ZBD of UPF1 interacts with UPF2, a factor also involved in NMD. SARS-Nsp13 is a component of the viral RNA synthesis replication and transcription complex (RTC). The SARS-Nsp13 CH/ZBD is indispensable for helicase activity and interacts with SARS-Nsp12, the RNA-dependent RNA polymerase. SARS-Nsp12 can enhance the helicase activity of SARS-Nsp13. UPF1, SARS-Nsp13 and EAV Nsp10 are multidomain proteins; their other domains include a 1B regulatory domain and a SF1 helicase core.
