Supplementary information

RENT1/hUPF1 also known as regulator of nonsense transcripts 1 or human UPF1 is an important factor in RNA surveillance mechanisms. It is an ATP-dependent helicase with a molecular mass of approximately 130 kDa. This protein is ubiquitously expressed in various tissues highlighting its importance across different biological systems. Mechanically UPF1 plays an essential role in the nonsense-mediated mRNA decay (NMD) pathway where it interacts with other core NMD factors to identify and degrade mRNAs containing premature stop codons.
Biological function summary

RENT1/hUPF1 ensures the quality control of mRNA by facilitating the rapid degradation of defective transcripts and thereby preventing the synthesis of potentially harmful truncated proteins. As part of the NMD complex UPF1 partners with proteins like UPF2 and UPF3 to form a surveillance mechanism that maintains cellular homeostasis. The complex cooperates to distinguish transcripts that require elimination from those necessary for normal cellular function.

Pathways

RENT1/hUPF1 integrates into essential cellular pathways beyond just NMD. The protein also links to the mRNA decay and translation initiation pathways playing significant roles alongside proteins such as SMG1 and eRF1. In these pathways UPF1 regulates gene expression by modulating mRNA stability and protein synthesis ensuring that only correctly processed mRNAs translate into proteins.

RENT1/hUPF1 connects to conditions like neurodevelopmental disorders and cancer. Dysregulation of UPF1 activity can lead to improper mRNA decay contributing to the accumulation of faulty transcripts which may drive disease pathogenesis. In particular UPF1 alterations are linked to the disruption of pathways involving key proteins like p53 which are critical in tumor suppression. Understanding UPF1's role in these disorders could present opportunities for therapeutic interventions.

Target data

RNA-dependent helicase required for nonsense-mediated decay (NMD) of aberrant mRNAs containing premature stop codons and modulates the expression level of normal mRNAs (PubMed : 11163187, PubMed : 16086026, PubMed : 18172165, PubMed : 21145460, PubMed : 21419344, PubMed : 24726324). 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 (PubMed : 11544179, PubMed : 25220460). Recruited by release factors to stalled ribosomes together with the SMG1C protein kinase complex to form the transient SURF (SMG1-UPF1-eRF1-eRF3) complex (PubMed : 19417104). In EJC-dependent NMD, the SURF complex associates with the exon junction complex (EJC) (located 50-55 or more nucleotides downstream from the termination codon) through UPF2 and allows the formation of an UPF1-UPF2-UPF3 surveillance complex which is believed to activate NMD (PubMed : 21419344). Phosphorylated UPF1 is recognized by EST1B/SMG5, SMG6 and SMG7 which are thought to provide a link to the mRNA degradation machinery involving exonucleolytic and endonucleolytic pathways, and to serve as adapters to protein phosphatase 2A (PP2A), thereby triggering UPF1 dephosphorylation and allowing the recycling of NMD factors (PubMed : 12554878). UPF1 can also activate NMD without UPF2 or UPF3, and in the absence of the NMD-enhancing downstream EJC indicative for alternative NMD pathways (PubMed : 18447585). Plays a role in replication-dependent histone mRNA degradation at the end of phase S; the function is independent of UPF2 (PubMed : 16086026, PubMed : 18172165). For the recognition of premature termination codons (PTC) and initiation of NMD a competitive interaction between UPF1 and PABPC1 with the ribosome-bound release factors is proposed (PubMed : 18447585, PubMed : 25220460). The ATPase activity of UPF1 is required for disassembly of mRNPs undergoing NMD (PubMed : 21145460). Together with UPF2 and dependent on TDRD6, mediates the degradation of mRNA harboring long 3'UTR by inducing the NMD machinery (By similarity). Also capable of unwinding double-stranded DNA and translocating on single-stranded DNA (PubMed : 30218034).
