Human Protein Atlas Number: | HPA025024 Human Protein Atlas characterization data |
The gene TGS1 (trimethylguanosine synthase 1) is mapped to human chromosome 8q11. The encoded protein has a methyltransferase domain, a K-homology domain for RNA binding, and a motif for SmB and SmD1 (small nuclear ribonucleoproteins) binding. The protein has a long form which localize in the cytoplasm and a short form which is present in the nucleus. It interacts with PRIP (proliferator-activated receptor-interacting protein).

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org),and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions
TGS1 (trimethylguanosine synthase 1) is responsible for the methylation of the m7G (7-methylguanylate) cap of RNA polymerase II transcribed snRNAs (small nuclear RNAs) and snoRNAs (small nucleolar RNAs), leading to the formation of 2,2,7-trimethylguanosine cap. In mice, absence of TGS1 activity causes embryonic lethality. It is also involved in gene regulation by interacting with proteins of cytoskeletal network and nuclear factors.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
