Hepatocyte nuclear factor 4 alpha (HNF4A) also known as NR2A1 (nuclear receptor subfamily 2, group A, member 1) is a nuclear receptor that in humans is encoded by the HNF4A gene. ^{[5] [6]}

Function

HNF-4α is a nuclear transcription factor that binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor that regulates the expression of several hepatic genes. This gene plays a role in development of the liver, kidney, and intestines. Alternative splicing of this gene results in multiple transcript variants. ^[7]

HNF4A is required for the PXR and CAR-mediated transcriptional activation of CYP3A4. ^[8] Genetic mutations in the HNF4A gene can influence the activity of HNF4α's downstream proteins such as CYP2D6, in vitro and in vivo. ^{[9] [10]}

The alkaloid berberine upregulates HNF4A expression. ^[11]

This gene plays a pivotal role in the expression and synthesis of SHBG, an important glycoprotein made primarily in the liver, ^[12] which in addition to lowering insulin-resistance also reduces levels of free Estrogen as-well as prolonging the half-life of testosterone.^{[ citation needed ]}

Function of HNF4A gene can be effectively examined by siRNA knockdown based on an independent validation. ^[13]

Clinical significance

Mutations in the HNF4A gene are associated with a form of diabetes called maturity onset diabetes of the young (MODY), ^[14] specifically MODY 1. At least 56 disease-causing mutations in this gene have been discovered. ^[15]

Increased amplification of hepatocyte nuclear factor 4 alpha has been observed in colorectal cancer. ^[16]

It has also associations with the appearance of Fanconi syndrome phenotypes which occurs due to a missense mutation of the gene. ^[17]

Interactions

Hepatocyte nuclear factor 4 alpha has been shown to interact with:

• Beta-catenin, ^[18]
• CREB binding protein, ^{[19] [20]}
• MED1, ^{[21] [22]}
• MED14, ^{[21] [22]}
• Small heterodimer partner ^[23]
• Testicular receptor 4, ^[24]
