Anti-HNF-4alpha Antibody, clone 4C19 ZooMAb^® Rabbit Monoclonal

Clone 4C19 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detect Hepatocyte nuclear factor 4-alpha. It targets an epitope within 16 amino acids from the C-terminal region.

Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

Hepatocyte nuclear factor 4-alpha (UniProt: P41235; also known as HNF-4-alpha, Nuclear receptor subfamily 2 group A member 1, Transcription factor 14, TCF-14, Transcription factor HNF-4) is encoded by the HNF4A (also known as HNF4, NR2A1, TCF14) gene (Gene ID: 3172) in human. HNF-4 is a transcriptional regulator that controls the expression of hepatic genes during the transition of endodermal cells to hepatic progenitor cells, facilitating the recruitment of RNA pol II to the promoters of target genes. It activates the transcription of CYP2C38 and represses the CLOCK-ARNTL/BMAL1 transcriptional activity. It is reported to be essential for circadian rhythm maintenance and period regulation in the liver and colon cells. It can undergo phosphorylation on tyrosine residues and that is shown to be important for its DNA-binding activity. However, phosphorylation at serine 313 by AMPK can reduce its ability to form homodimers and bind DNA. Mutations in HNF4A gene are known to cause type II diabetes. Changes in the HNF4A gene can reduce the amount of insulin that is produced by the pancreas. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
