'''Hepatocyte nuclear factor 4 alpha''' ('''HNF4A''') also known as '''NR2A1''' (nuclear receptor subfamily 2, group A, member 1) is a [[nuclear receptor]] encoded by the {{gene|HNF4A}} gene.


<!-- The PBB_Summary template is automatically maintained by Protein Box Bot.  See Template:PBB_Controls to Stop updates. -->
HNF-4α is a nuclear [[transcription factor]] that binds DNA as a homodimer. The encoded protein controls the expression of several genes, including [[HNF1A|hepatocyte nuclear factor 1 alpha]], a transcription factor which regulates the expression of several hepatic genes. This gene plays a role in development of the {{SWL|target=liver|type=involved_in_development_of}}, {{SWL|target=kidney|type=involved_in_development_of}}, and {{SWL|target=intestines|type=involved_in_development_of}}. Alternative splicing of this gene results in multiple transcript variants.<ref name="entrez">{{cite web | title = Entrez Gene: HNF4A hepatocyte nuclear factor 4, alpha| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3172| accessdate = }}</ref>

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.[1][2]

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 which 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.[3]

HNF4A is required for the PXR and CAR-mediated transcriptional activation of CYP3A4.[4] Genetic mutations in the HNF4A gene can influence the activity of HNF4α's downstream proteins such as CYP2D6, in vitro and in vivo.[5][6]

The alkaloid berberine upregulates the expression of HNF4A.[7]

This gene also plays a pivotal role in the expression and synthesis of SHBG, an important glycoprotein made primarily in the liver, which in addition to lowering insulin-resistance also serves in reducing 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.[8]

Clinical significance

Mutations in the HNF4A gene are associated with a form of diabetes called maturity onset diabetes of the young (MODY).[9]

Increased amplification of hepatocyte nuclear factor 4 alpha has been observed in colorectal cancer.[10]

Interactions

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