U2 auxiliary factor (U2AF), comprised of a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the U2AF large subunit which contains a sequence-specific RNA-binding region with 3 RNA recognition motifs and an Arg/Ser-rich domain necessary for splicing. The large subunit binds to the polypyrimidine tract of introns early during spliceosome assembly. Multiple transcript variants have been detected for this gene, but the full-length natures of only two have been determined to date.

Flow cytometric analysis of U2AF2 expression in HepG2 cells using U2AF2 antibody . Green, isotype control; red, U2AF2.

Immunocytochemical staining of HepG2 cells with U2AF2 antibody . Nuclei were stained blue with DAPI; U2AF2 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: Medium. Scale bar, 20 μm.

Western blotting analysis using U2AF2 antibody . Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with U2AF2 antibody and HRP-conjugated goat anti-rabbit secondary antibody respectively. Image was developed using FeQ™ ECL Substrate Kit .

Western blotting analysis using U2AF2 antibody . U2AF2 expression in wild-type (WT) and U2AF2 shRNA knockdown (KD) HT-1080 cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with U2AF2 antibody and HRP-conjugated goat anti-rabbit secondary antibody respectively. Image was developed using NaQ™ ECL Substrate Kit .
