Description

UPF1 serves as a central regulator of nonsense-mediated mRNA decay, a critical surveillance pathway that identifies and degrades transcripts containing premature termination codons. As an ATP-dependent RNA helicase, UPF1 plays essential roles in maintaining transcriptome fidelity and has emerged as a key factor in understanding how cells manage aberrant mRNA species. Research into UPF1 function spans diverse areas including cancer biology, genetic disease mechanisms, and fundamental RNA quality control processes.

This recombinant monoclonal antibody, clone 8D12, offers researchers the reproducibility advantages inherent to recombinant technology. Because the antibody sequence is defined and production occurs through controlled expression systems, you can expect consistent performance across experiments and over time, eliminating the lot-to-lot variability that can complicate long-term studies or multi-site collaborations.

Raised in rabbit against a synthetic peptide derived from human UPF1, this antibody has been validated for flow cytometry applications with human samples. Validation studies using HeLa cells demonstrate clear detection of intracellular UPF1, with flow cytometry experiments showing distinct signal separation from isotype control when cells are fixed and permeabilized. The recommended working dilution range of 1:50 to 1:200 for flow cytometry provides flexibility to optimize signal intensity based on your specific experimental conditions and instrument sensitivity.

Supplied in a glycerol-containing buffer optimized for long-term storage stability, this unconjugated format allows pairing with your preferred secondary detection system. Whether investigating nonsense-mediated decay mechanisms, studying UPF1's role in cellular stress responses, or examining its involvement in disease contexts, this antibody provides a reliable tool for characterizing UPF1 expression at the single-cell level.

Target Background

Function

RNA-dependent helicase and ATPase required for nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. 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. 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 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. 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. UPF1 can also activate NMD without UPF2 or UPF3, and in the absence of the NMD-enhancing downstream EJC indicative for alternative NMD pathways. Plays a role in replication-dependent histone mRNA degradation at the end of phase S; the function is independent of UPF2. 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. The ATPase activity of UPF1 is required for disassembly of mRNPs undergoing NMD. Essential for embryonic viability. Together with UPF2 and dependent on TDRD6, mediates the degradation of mRNA hardoring long 3'UTR by inducing the NMD machinery.
