Forkhead Box Protein A3 (FOXA3)
FOX-A3; HNF3G; Hepatocyte Nuclear Factor 3,Gamma
encodes a member of the forkhead class of DNA-binding proteins. These hepatocyte nuclear factors are transcriptional activators for liver-specific transcripts such as albumin and transthyretin, and they also interact with chromatin. Similar family members in mice have roles in the regulation of metabolism and in the differentiation of the pancreas and liver. The crystal structure of a similar protein in rat has been resolved.
Mincheva et al. (1997) used fluorescence in situ hybridization to map the HNF3G gene to human chromosome 19q13.2-q13.4. By analysis of RFLPs in interspecific backcross mice, Avraham et al. (1992) mapped the mouse Hnf3-gamma gene to the proximal region of chromosome 7.
