Functional Information
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. [provided by RefSeq]

Interactions

If available, interactions between genes and transcription factors are displayed. These interactions have been extracted manually from PubMed abstracts by Genomatix experts. The table shows the type of the interaction (e.g. activating), the sentences of the PubMed abstracts from which the information has been derived from as well as a link to the complete PubMed abstracts.

Example:

Interactions
Genes	Type	Description	Citation
CEBPA cooperates with HNF4A	-	Using different molecular approaches, we demonstrate that hepatocyte nuclear factor (HNF4alpha), CAAT/enhancer-binding protein-alpha (C/EBPalpha), C/EBPbeta, and cAMP response element-binding protein (CREB) are involved in the potentiated PKA responsiveness: in the distal region, via one HNF4alpha- and one C/EBP-binding sites, and in the proximal region, via two HNF4alpha and two CREB-binding sites.
PPARGC1A regulates HNF4A	-	The coactivator PGC-1 enhanced transcriptional activity of HNF-4, and this enhancement was suppressed by rifampicin-activated PXR.
CREB1 cooperates with HNF4A	-	Using different molecular approaches, we demonstrate that hepatocyte nuclear factor (HNF4alpha), CAAT/enhancer-binding protein-alpha (C/EBPalpha), C/EBPbeta, and cAMP response element-binding protein (CREB) are involved in the potentiated PKA responsiveness: in the distal region, via one HNF4alpha- and one C/EBP-binding sites, and in the proximal region, via two HNF4alpha and two CREB-binding sites. These data strongly suggest that the cAMP responsiveness of the Glc6Pase promoter requires a tight cooperation between a proximal and a distal region, which depends on the presence of several HNF4alpha-, C/EBP-, and CREB-binding sites, therefore involving an intricate association of hepatic and ubiquitous transcription factors.

Transcripts

All transcripts of the gene which have been mapped to the genomic sequences are listed. Redundant transcripts sharing an identical exon/intron structure with an other transcript are marked respectivly. They are only listed here and can not be accessed in Eldorado. The table shows the Genomatix transcript ID, the accession number of the mapped cDNA sequence and the description of the cDNA sequence.

Example:

Transcripts
TranscriptID	cDNA Accession	Description
GXT_22544954	XM_001110097	Transcript derived from mapping of the cdna XM_001110097 from mml
GXT_2815203	NM_178850	Homo sapiens hepatocyte nuclear factor 4, alpha (HNF4A), transcript variant 3, mRNA. This variant (3) includes an alternate segment compared to variant 2, that causes a frameshift. The resulting isoform (c) is shorter and has a distinct C-terminus compared to isoform b.
GXT_2807165	NM_178849	Homo sapiens hepatocyte nuclear factor 4, alpha (HNF4A), transcript variant 1, mRNA. This variant (1) uses an alternate in-frame splice site in the 3' coding region compared to variant 2, resulting in a shorter isoform (a) compared to isoform b.
GXT_21914753	NM_175914	Homo sapiens hepatocyte nuclear factor 4, alpha (HNF4A), transcript variant 4, mRNA. This variant (4) also known as variant 8, differs in the 5' UTR and has multiple coding region differences, compared to variant 2. These differences cause translation initiation at an upstream AUG and an isoform (d) with a shorter N-terminus compared to isoform b.
