  Identified as Transcription Factor. DNA binding sites are described by V$NR2F.

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 encoding several different isoforms. [provided by RefSeq, Apr 2012]

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.

Additionally, a link to all gene-gene co-citations from the Genomatix Literature Mining is available (will open a new window).

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.
PubMed Link
PPARGC1A regulates HNF4A -
  • The coactivator PGC-1 enhanced transcriptional activity of HNF-4, and this enhancement was suppressed by rifampicin-activated PXR.
PubMed Link
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 respectively. Prior to ElDorado 04-2019, redundant transcripts are only listed here and cannot be accessed in Eldorado. Starting with ElDorado 04-2019, information on redundant transcripts is shown, e.g. in the "Alternative Transcripts" view. The table shows the Genomatix transcript ID, the accession number of the mapped cDNA sequence, the description of the cDNA sequence, and the Pfam family.
