功能Component of the CRD-mediated complex that promotes MYC mRNA stabilization. Binds to pre-mRNA. Has high affinity for scaffold-attached region (SAR) DNA. Binds to double- and single-stranded DNA and RNA.
序列相似性Contains 1 B30.2/SPRY domain. Contains 1 SAP domain.
翻译后修饰Extensively phosphorylated. Arg-733 and Arg-739 are dimethylated, probably to asymmetric dimethylarginine.
细胞定位Nucleus. Cytoplasm. Cell surface. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Component of ribonucleosomes. Also found associated with the cell surface.

Immunocytochemistry/ Immunofluorescence - hnRNP U antibody (ab20666)
ICC/IF image of ab20666 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab20666, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).
Panel A shows localisation of ab20666 to the nuclei, Panel B has the Alexa Fluor® 488 channel removed for comparison.

Anti-hnRNP U antibody - ChIP Grade (ab20666) at 1 µg/ml + HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate (ab27252) at 20 µg
ab20666 staining hnRNP U in paraffin embedded human skin tissue. The samples were incubated with ab20666 (1/250 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6. ab20666 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines.
Immunocytochemistry/ Immunofluorescence - Anti-hnRNP U antibody (ab20666)
ab20666 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab20666 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Immunofluorescence analysis of murine embryonic stem cells, staining hnRNP U with ab20666.
Cells were fixed with paraformaldehyde, permeabilized with 0.25% Triton X-100 and blocked in 0.1% Triton X-100/10% FCS for 20 min.
Samples were incubated with primary antibody (1/500) for 2 hours before incubating with an AlexaFluor®488-conjugated goat anti-rabbit IgG (1/500) for 1 hour.
