Our Abpromise guarantee covers the use of ab31478 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
IHC-P: 1/50 - 1/100.
WB: 1/500 - 1/1000. Predicted molecular weight: 68 kDa.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionNuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Can activate the transcriptional activity of TFF1.
Sequence similaritiesBelongs to the nuclear hormone receptor family. NR3 subfamily.
Contains 1 nuclear receptor DNA-binding domain.
DomainComposed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
modificationsPhosphorylated by cyclin A/CDK2. Phosphorylation probably enhances transcriptional activity.
Glycosylated; contains N-acetylglucosamine, probably O-linked.
Ubiquitinated. Deubiquitinated by OTUB1.
Dimethylated by PRMT1 at Arg-260. The methylation may favor cytoplasmic localization.
Palmitoylated (isoform 3). Not biotinylated (isoform 3).
Cellular localizationNucleus. Cytoplasm. Cell membrane. A minor fraction is associated with the inner membrane and Nucleus. Cytoplasm. Cell membrane. Associated with the inner membrane via palmitoylation.

ab31478 staining human non-small cell lung cancer tissue sections by IHC-P. Sections were formaldehyde fixed and subjected to heat mediated antigen retrieval in 10 mM sodium citrate (pH 6) prior to blocking with a commercially available blocking reagent for 20 minutes at 22°C. The primary antibody was diluted 1/200 and incubated with the sample for 24 hours at 4°C. A HRP conjugated antibody was used as the secondary.
