In vitro oligonucleotide binding assay. C-myc-tagged HNF4A protein (OriGene TP317863) was added to a solution of double-stranded oligonucleotides labeled with biotin. Oligonucleotides consisted of DNA sequences of wild-type (WT) or HV SLC4A5 alleles. After incubation for 30 min, streptavidin Alexa Fluor 647 was added to label the oligonucleotides; anti-c-Myc antibody was then added, followed by magnetic protein A/G to capture HNF4A-oligonucleotide complexes. The samples were washed and read on a microplate reader. HNF4A binding is increased in HV relative to WT sequence. Figure cited from PLoS ONE, PMID: 29642240

• Purity: > 80% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: 25 mM Tris.HCl, pH 7.3, 100 mM glycine, 10% glycerol
• Bioactivity: HNF4A Activity Verified in a DNA-binding Assay: HNF4A (TP317863, transcript variant 2) activity was measured in a colorimetric DNA-binding assay. Purified HNF4A protein containing a C-terminal MYC/DDK tag was incubated with biotinylated double-stranded oligonucleotide containing the HNF4A consensus DNA-binding sequence (see below). Following incubation, the reaction was transferred to a streptavidin-coated microplate to allow capture of the DNA-protein complex. After washing, the captured protein was detected with an anti-DDK peroxidase conjugate and colorimetric signal detection with TMB. Specificity of the protein-DNA interaction was confirmed by carrying out the binding in the presence of an unlabeled competitor oligonucleotide and by comparison to binding to an oligonucleotide containing a mutation in the consensus binding sequence.

• Summary: 'The protein encoded by this gene is a nuclear transcription factor which binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor which regulates the expression of several hepatic genes. This gene may play a role in development of the liver, kidney, and intestines. Mutations in this gene have been associated with monogenic autosomal dominant non-insulin-dependent diabetes mellitus type I. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms. [provided by RefSeq, Apr 2012]'
