Hepatocyte nuclear factor 4 gamma (HNF4G) also known as NR2A2 (nuclear receptor subfamily 2, group A, member 2) is a nuclear receptor that in humans is encoded by the HNF4Ggene.[5][6][7]
Function
HNF4G is a transcription factor that has been shown to play a significant role in intestinal epithelial cell differentiation and function. Research using integrative multi-omics analysis of intestinal organoid differentiation has revealed that HNF4G acts as a master regulator of gene regulation in differentiation towards the enterocyte lineage.[8] The study demonstrated widespread binding to promoters and enhancers that are activated in enterocytes, and that the loss of Hnf4g results in a partial loss of enterocyte differentiation, indicating its importance in maintaining the enterocyte lineage.
