UPF1 (or regulator of nonsense transcripts 1 homologue) is an essential RNA helicase that detects mRNAs containing premature stop codons and triggers their degradation. Together with UPF2 and UPF3, forms a surveillance complex, in which UPF2 acts as a bridge between UPF1 and UPF3. UPF2 and UPF3 are non-enzymatic components of the complex that stimulate the activity of UPF1 [1, 2]. UPF1 has a N-terminal cysteine/histidine-rich zinc-binding domain (CH/ZBD), a regulatory 1B domain, followed by a helicase core that belongs to superfamily 1 (SF1). This entry represents 1B domain of UPF1 which has a regulatory role. It suffers conformational changes from an inhibitory state to a transition-state complex that modulate RNA binding [1, 2].
This family of domains contain a P-loop motif that is characteristic of the AAA superfamily. Many of the proteins in this family are conjugative transfer proteins.

UPF1 is an essential RNA helicase that detects mRNAs containing premature stop codons and triggers their degradation. This domain contains 3 zinc binding motifs and forms interactions with another protein (UPF2) that is also involved nonsense-mediated mRNA decay (NMD) [1].
