Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
Splicing factor 3 subunit 1 is a protein encoded by the SF3A1 gene in humans and is localized to human chromosome 22. It is a conserved heterotrimeric complex essential for pre-mRNA splicing. It helps in initiating the first step of the splicing reaction. It is a component of the mature U2 small nuclear ribonucleoprotein particle (snRNP) and its three subunits of 60, 66 and 120kDa are essential for splicing. SF3A1 provides the major nuclear localization signal. It is essential for spliceosomal assembly. The protein contains two tandem SURP domains (SURP1 and SURP2) and SURP2 is responsible for binding to SF3a60 (that contributes to nuclear import).
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:
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.

SF3a is an evolutionarily conserved heterotrimeric complex essential for pre-mRNA splicing. It functions in spliceosome assembly within the mature U2 snRNP (small nuclear ribonucleoprotein particle), and its displacement from the spliceosome initiates the first step of the splicing reaction. We

Mammalian splicing factor SF3a consists of three subunits of 60, 66, and 120 kDa and functions early during pre-mRNA splicing by converting the U2 snRNP into its active form. A cDNA encoding the 120-kDa subunit of SF3a has been cloned.

The SF3a complex, consisting of SF3a60, SF3a66, and SF3a120, in 17S U2 snRNP is crucial to spliceosomal assembly. SF3a120 contains two tandem SURP domains (SURP1 and SURP2), and SURP2 is responsible for binding to SF3a60. We found that the SURP2
