REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation:
Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10).
This means that the protein of interest is denatured.
If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

PUS1 also known as pseudouridine synthase 1 is an enzyme responsible for catalyzing the isomerization of uridine to pseudouridine in RNA molecules. This protein has a mass of approximately 50 kDa and expresses widely in both the cytoplasm and mitochondria of human cells. Pseudouridine is the most abundant RNA modification and plays an important role in RNA stability and structure. The presence of PUS1 can vary among cell types supporting its necessity in diverse cellular contexts.
Biological function summary
The modification of RNA by PUS1 improves the stability and folding of the RNA structure aiding its functionality. The enzyme is not part of a larger complex but acts independently to achieve its role in RNA modification. Pseudouridine created by PUS1 permits enhanced base stacking and hydrogen bonding which influences the translation process and the overall efficiency of protein synthesis. This modification is important for the proper functioning of tRNA and rRNA ensuring fidelity during protein translation.
Pathways
PUS1 plays an essential role in the RNA processing and modification pathways. Its activity integrates into pathways such as ribosome biogenesis and RNA quality control. Particularly it interacts with other RNA-binding proteins and enzymes like TRUB1 another pseudouridine synthase which also contributes to the maturation of structured RNAs. These pathways are vital for maintaining cellular homeostasis and responding to various physiological demands.
Mutations in PUS1 are linked to mitochondrial myopathy and sideroblastic anemia a rare condition characterized by muscle weakness and anemia. These disorders illustrate the critical impact of RNA modification defects on cellular energy production and red blood cell formation. In these conditions PUS1 may interact with defective proteins leading to impaired pseudouridylation disrupting normal cellular functions and contributing to disease pathology. Understanding the role of PUS1 might provide insights into potential therapeutic strategies for such disorders.
