Whole cell extracts (15 μg total protein per lane) from indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with Purified anti-UPF1 (clone W22273D) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-rat IgG (Cat. No. 405405). Direct-Blot™ HRP anti-GAPDH (Cat. No. 607903) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

    A-431 cells were fixed with Fixation Buffer (Cat. No. 420801) for 10 minutes and permeabilized with 100% ice-cold methanol for 10 minutes, and blocked with 5% FBS at room temperature. Cells were then stained with Purified Rat IgG2a, κ Isotype Ctrl (Cat.

Description

UPF1 is a crucial RNA helicase and an integral part of the nonsense-mediated mRNA decay (NMD) pathway, a cellular quality control mechanism that ensures the fidelity of gene expression by degrading mRNAs containing premature termination codons. UPF1 contains several key domains that contribute to its function: a N-terminal cysteine-histidine-rich domain (CH domain), a central helicase domain, and a C-terminal domain. The CH domain is involved in regulating the ATPase and helicase activities of UPF1, while the helicase domain facilitates ATP-dependent unwinding of RNA secondary structures. The C-terminal domain interacts with other NMD factors and regulatory proteins. 

UPF1 facilitates mRNA decay through two primary mechanisms: endonucleolytic cleavage and exonucleolytic decay. SMG6, an endonuclease, directly cleaves the mRNA near the PTC, while SMG5 and SMG7 recruit exonucleases to degrade the RNA from the 5’ and 3’ ends. UPF1's helicase activity is pivotal in remodeling RNA-protein complexes and unwinding secondary structures, thereby allowing exonucleases to efficiently degrade the target mRNA.

Beyond its role in NMD, UPF1 is involved in other RNA surveillance and regulatory pathways. It participates in Staufen-mediated mRNA decay (SMD), which targets specific mRNAs bound by the Staufen protein. UPF1 is also implicated in the regulation of histone mRNA decay and telomere maintenance, indicating its versatility in RNA metabolism.

Mutations or dysregulation of UPF1 and the NMD pathway have been linked to various human diseases, including cancer, neurodevelopmental disorders, and genetic diseases caused by nonsense mutations.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.25 - 1.0 µg/mL. For immunohistochemistry, a concentration range of 1.0 - 10.0 µg/mL is suggested. For immunocytochemistry, a concentration range of  1.25 - 10.0 μg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

For use in immunohistochemistry on formalin-fixed paraffin-embedded tissue (IHC-P), it is recommended to perform antigen retrieval using Citrate Buffer, 10X (Cat. No. 420902) or Tris-EDTA pH 9.0 Antigen Retrieval Buffer (10X) (Cat. No. 422704).

For use in immunocytochemistry (ICC), it is recommended to fix/permeabilize with either of the following:
-Fixation buffer (Cat. No. 420801) with 0.5 % Triton X-100
-Fixation buffer (Cat. No. 420801) with 100% ice-cold methanol
-100% ice-cold methanol only

This antibody does not cross react with mouse UPF1.
